KSH is pdksh

KSH is pdksh

[Galen Boyer]

After reviewing some archives, I find that pdksh is cygwin's
version of ksh.  Is this still available and where do I get it?
My c:/cygwin/bin doesn't contain it.

Thanks.

pdksh is not Cygwin's version of ksh but rather an open-source version of
ksh which can be built and used under Cygwin.  You can check the Cygwin 
home page for pointers to related sites with ported software and you can
also look in the mail archives for indications that others have ported it
and made it available.  Alternatively, you can just download the source 
from your favorite GNU site and build it yourself.

Ooops, pdksh is _not_ the Cygwin version of ksh. Pdksh is an open
source implementation of ksh which isn't bound to a specific OS.
Latest sources are available in ftp://ftp.cs.mun.ca/pub/pdksh , an
OLD Cygwin binary which only supports binmode mounts is available in
ftp://ftp.franken.de/pub/win32/develop/gnuwin32/cygwin/porters/Vinschen_Corinna/B20

As Larry explained, this is something different.

However, as I've come to discover after much pain, if you're already
using Cygwin, there isn't much point to installing pdksh.  It's easy
enough to create a symlink from "/usr/bin/ksh.exe" to
"/usr/bin/bash.exe".  Poof.  You have Korn shell.  As far as I can
tell, Bash can substitute for Korn shell in every area I'm familiar
with.

I knew that once upon a time.  Thanks for reminding me.  Hey miss bash
maintainer how about a postinstall script to ln -s bash.exe ksh.exe?

Nope, bash is not ksh. There are quite a few ksh93 features that are not
implemented in bash (and possibly quite a few from ksh88 days, but I
don't have details on those).

Please don't. I personally very much dislike misleading links. If people
want ksh, they should go and port it using the AT&T's now open source
ksh93.

I'm not going to dispute that, but could you please give us some
examples of ksh88 and ksh93 features that aren't transparently
available in bash?  I'd like to know exactly what problems I could run
into.  I haven't noticed anything yet.  Does someone know which
canonical ksh version (ksh88 or ksh93) the Solaris ksh matches?

It would sure be nice to bring a maintainable ksh into the Cygwin
fold, just for the sake of increased Unix compatibility.

Re: KSH is pdksh

[Matthew Smith]

For what it's worth, I started taking a stab at compiling AT&T's ksh.  Man,
they certainly do use some wacky packaging tools.  At any rate, here are
some of the problems that I encountered, and what I did about them.

1) The 'package' script wants to see getopts.  Thus, I made sh a link to
bash to work around this.

2) The 'package' script always seemed to fail, complaining about not being
in the package root (when it was).  I solved this by editing the package
script to not exit if that particular error happened.

3) I made a link from gcc->cc for convenience sake (read: laziness).

At this point the 'mamake' utility seems to start configuring/making things.
However, it spits out the following errors:

/home/matts/att/src/lib/libast/include/ast_std.h:672: conflicting types for
`rea
d'
/usr/include/sys/unistd.h:72: previous declaration of `read'
/home/matts/att/src/lib/libast/include/ast_std.h:690: conflicting types for
`wri
te'
/usr/include/sys/unistd.h:99: previous declaration of `write'

Can anyone suggest an elegant way around this?

thanks,
-Matt Smith

Newlib's non-posix'ness [Re: KSH is pdksh]

FYI, it's newlib that provides the incorrect declaration. It's one of 
those cases where newlib's declarations don't quite match POSIX/UNIX98, 
but small enough that nobody has bothered to fix those. Mostly has to 
do with signed vs unsigned (eg., size_t vs ssize_t) and those little
nits. Interestingly enough, someone, quite possibly Joel Scherrill, had 
gone through newlib and fixed most of these, if not all, but only for 
RTEMS! 

POSIX:
    ssize_t read (int, void *, size_t);

newlib:
    #ifdef __rtems__
      ssize_t read (int, void *, size_t);
    #else
      int read (int, void *, size_t);
    #endif

Perhaps Chris and/or DJ know why that is the case.

When you have a conflict between Glenn Fowler's AT&T AST and another 
library, chances are that AST is doing the right thing.

Mumit

There's been other chatter about problems with __rtems__ and Cygwin on
the newlib list; but, it was wrt pthreads.  I've CCed newlib on this.

Because the only thing that Joel cares about is RTEMS, basically.  He
broke Cygwin builds a couple of times with his changes and, I assume,
rather than try to build Cygwin after a change, opted to just
conditionalize everything.

>When you have a conflict between Glenn Fowler's AT&T AST and another

Probably, but any package that doesn't build because it relies on read
being defined as ssize_t is not exactly portable.

Well, if I could find the equivalent to getopts, I think I could
get along without kornshell.  I found this feature to be
extremely useful when I was a heavy-duty KSH programmer, and now
I am coding a few scripts again and would like to take advantage
of it.

I got notified of the man pages for bash.  It looks really nice
for scripting.  getopts is just how I expected.  Whoa!  Cygwin is
excellent!

Problem with Windows .lnk files treated as Symlinks

[Martin Oberhuber]

Hello,

since cygwin-1.3, Windows *.lnk files are treated as UNIX
symbolic links by default.

We rean into a problem where we wanted to use the "cp" 
command to copy a Windows *.lnk shortcut to a new place.
This worked alright with previous cygwin versions, but
with 1.3, the file referenced was copied instead of the
*.lnk file. 

One problem with this behavour is that additional attributes
of the *.lnk file (like parameters passed to the program
referenced, or an icon associated) are not copied in that 
case.

Looking at options of the CYGWIN environment variable as
well as options of the "cp" command, I found NO WAY of
copying the *.lnk file instead of the file referenced!
Even "cp -d", which is documented to preserve symbolic
links (and works like that on Linux) did not work.
Setting CYGWIN=nowinsymlinks only affects link creation,
but not link interpretation by "cp".

Taking into account that Windows Shortcuts are more than
UNIX symbolic links, and that thus a one-to-one mapping
is always problematic, I would suggest the following to
preserve a clean environment as well as backward
compatibility:

1.) Only *.lnk files created by Cygwin (with the special
    cygwin header), should be treated as symbolic links when 
    they are read. If the *.lnk file is not a "cygwin *.lnk"
    with its special header, it should be treated as a plain 
    file.
    If this is not observed, important information may be lost 
    (also think about programs like tar that cannot reproduce 
    an exact image of the original file system if *.lnk files 
    are not completely copied).

2.) If CYGWIN=nowinsymlinks is set, not only symbolic link
    creation but also symbolic link interpretation should
    be "classical", i.e. *.lnk files are treated as files.

Please keep me informed on your plans regarding this issue.

Thanks in advance,
Martin Oberhuber

Since the goal of making Cygwin symbolic links use the Windows short-cut 
mechanism was to allow Windows and Cygwin to interoperate in this area, I
don't see any benefit to trying to break this with your suggestion.  
Certainly, this is the way things worked prior to this change since short-cuts
were not understood by Cygwin and Cygwin symbolic links were not understood
by Windows.  If you need this division, you want to use the old mechanism.

This may be indicative of a bug.

Watch the list and you'll see any discussion of this.  Or send in a patch for
(2) for consideration.

This isn't a bug.  The setting is only to force creation of old style symlinks.
Either style is supposed to be recognized on "reading".  I suppose the option
could have been "nocreatewinsymlinks"...

help on compiling perl/ nt with cygwin. gnu c lib missing

[john z]

im trying to install perl5.05_54 on a brand new nt box. it has a vanilla
setup. b20.1 full was installed and it seemed ok.

when i try the cygwin installation for perl, i get an error that 'gnu c
libary' not found. i modified ld2, and gcc2 and it seemed to pass that test.

can somebody tell me what i am missing. i did NOT install the gnu c library
(thought enough of it came over with full/ egcs.

am i missing some symbols?

(and please dont tell me i should switch to activestate perl). as is just
fine, but i want to use modules not yet supported.

Hi John,

Can't answer your question, but:
5.005_54 is a developers release, not a production release - is that,
what you want ?
AFAIK the latest production release is 5.005_02 (perhaps 03 meanwhile).

Re: help on compiling perl/ nt with cygwin. gnu c lib missing

[Peter Moulder]

I think when I compiled perl, I supplied ,the path of directory
containing libc` in response to one of the configuration questions,
i.e. the default answer did not include this information.

I don't know whether or not that is the solution to your problem.

Oh yes, another thing I did was to create some symlinks to satisfy

Re: OpenGL and glut with B20.1

[Suhaib M. Siddiqi]

Brian Kasper last week sent me a set of Mesa 3.0 libraries for
Cygwin-B-20.
He did a really good job in porting Mesa to Cygwin-B20.

You can find precompiled LessTif 0.87 at
ftp://ftp.lesstif.org/pub/hungry/lesstif/bindir for
Cygnus-B-20.  I compiled them.  LessTif organization requested to
redistribute them
through LessTif ftp server instead of a third party site.  The Cygnus
precompiled version in that
archive is missing libXlt.a and libXlt.dll.  If you need Xlt port for
Cygnus-B20, let me know and I will
send it to you.  Beware, it is a 1.78 MB big file.

For a first-time install, go to http://cygwin.com/ and click on the
"Install Cygwin Now" icon.  The only choices you should have to make
are (0) that you want to install from the internet, (1) where to
install it on your machine, and (2) whether to use IE5, a direct
connection, or a proxy to access the internet.

Note that the "Default text file type" might be important, depending
on what you're using this for.  It will default to "Unix", as opposed
to "DOS".  If you have non-cygwin programs that expect DOS line
endings, and they might be reading files you would create while using
Cygwin, then they might not work properly if you set it to "Unix".
Just make sure you understand the choice.

An example list of applications that have some trouble reading files with
only UNIX line endings (newline only) include notepad, just about any old
DOS (and I mean DOS, not Windows) program, and VC++ if the file in question 
will also be edited by the class wizard.  With the exception of the VC++ 
issue, which is rather obscure, there's a solution to each of the other 
problems (i.e. replace them with programs that understand UNIX style line 
endings - there's lots of good alternatives here).  Every other Windows 
program I've used can read UNIX line endings just fine, because the underlying 
Win32 API call for accessing files supports reading newline-only line endings. 
I'm sure there are some other utility programs out there that still trip over 
UNIX line endings too but in general, this is pretty rare.

Unless I'm misunderstanding something, the public domain Korn shell is
another application that can't deal with Unix line endings.  For some
people, this is more likely to be an issue than notepad or vc++.

Right.  It depends on the utilities you use, how old they are, and whether
they make use of the Win32 API for opening text files or not.  There are 
some utilities out there which are poorly ported to Windows.  Other than
utilities like these and the utilities I mentioned which are part of the
utilities that come with Windows (or its development environment), every
other Windows program that I've seen can read a text file with UNIX line 
endings, even edlin!;-)  (Yuck, who wants that!;-))  However, if you're 
concerned about some obscure program you know you need to interact with 
files created and manipulated with Cywgin tools, pick "DOS" files at Cygwin 
install time.  If you don't have reason to fear some utility you're using 
won't work with Cygwin created/manipulated files, stick with the defaults.  
Defaults exist because they generally give the best results for the majority. 
YMMV!;-)

A Cygwin build of pdksh produces a ksh which understands UNIX file
endings.  You may need to use the -mno-win32 switch though.

The one I'm using is built with Cygwin, so perhaps the "-mno-win32"
option is needed.  I don't believe I used that switch when I built it.
I'll keep this in mind.

It probably needs to be compiled with -mno-win32 and linked with
/usr/lib/textmode.o .

Drive with cygwin moved from "E:" to "D:", how to fix?

[David M. Karr]

My colleague got a PC which was originally configured with the drive
with most of his work (including the cygwin installation) being "E:"
(the CD was "D:").  We realized it needed to be on "D:" to easily work
with some scripts we have.  We had that done, but now I see that
"mount" still thinks that Cygwin is installed on drive "E:".  This
causes some odd symptoms, although many things still work.  What is
the easiest way to reset Cygwin to know it's installed on drive "D:"?

Just remount all the E: mounts to be D:, either with umount/mount or
with mount -f

Ok, after fiddling with this for a while, I finally got his new mount
table to look the same, except the "e:"s changed to "d:".  That looks
correct.

I see two odd symptoms on this new PC, however, which are probably
related.  On my PC, when I do "ls /usr", it gives me a valid listing
of what's in "d:/cygwin/usr".  On his PC, when I do "ls /usr", it says
"No such file or directory".  When I list "/usr/bin" on my PC, it also
lists fine.  When I list "/usr/bin" on his PC, it mostly is fine,
except it says "ls: ..: No such file or directory".  What could be the
cause of this?

Ah.  I figured it out.  You probably would have seen it if I had
included the new mount table, which wasn't EXACTLY correct.  The mount
for "/" should have been "d:\cygwin", but I had it as "d:\".  Once I
redid that mount, I got "/usr" back.

Thanks again.

Change the entries in windows registry by hand.

or:
delete /etc/setup/installed.db
delete setup.ini

run setup again, it will install all new, at the end of setup, when it
asks if there to make a link on the desktop and add to start menu, 
choose both, then setup should update the registry also.

Quick setup script "taxidermy.pl"

[Soren Andersen]

[-- Attachment #1: Type: text/plain, Size: 2079 bytes --]

Hello,

I spent quite a bit of the recent holiday season setting up the latest Cygwin 
on several systems (one Win98, one Win95, one WinNT) since it is much 
more fun to work with now, that so much great effort has resulted in fewer 
bugs. Playing (*laziness*).

I noticed that I wanted to have a fast way to just mount every logical drive 
on each system to it's appropriate POSIX mount point ('X:' to '/x')  and 
that, being the incredibly *impatient* hacker I am, I disliked the repetitious 
nature of that task when done manually.

Since I tend to have Perl installed on every system I can get my hands on 
for even a few moments (*hubris*), I cooked up a little Perl script to make 
this automatic. What it doesn't yet do is check for existing mounts and 
`umount' them before re-mounting anything (or skip them entirely). That's 
a future To-Do refinement. This is just a rough script but I thought maybe 
somebody would want to use it especially on a brand-new Cygwin 
installation.

One problem, however: the script uses a Perl module that isn't standard: 
Win32::API. It's on CPAN and at http://dada.perl.it/#api (on that site is a 
PPM package to make it an easy install to ActivePerl -- *laziness*). But 
when I ran the script from Cygwin bash the perl process faulted (memory 
access violation I think). So, *don't run it in bash* but rather from cmd.exe 
(or command.com if you must use that brain-damaged shell*). I think it 
likely that a Win32::API compiled for a Cygwin Perl might not have this 
problem, but I don't know quite enough of these matters for that to be 
more than a speculation at this time. As a matter of fact, I would love to 
know if anyone else gets Win32::API -- a really powerful module to access 
arbitrary Win32 API calls from system DLLs -- built from source using 
Cygwin or MinGW.

I have attached the script to this message, since it is relative short.

   Best,
       soren andersen

* When you aren't using Cygwin.

P.S. "Why `taxidermy.pl'?" Aww come ON! "mounting"(as in hunting 
trophies or monster trout) -> taxidermy, get it?

NTEmacs shell/CygWin: should control-C work?

[Daniel Barclay]

If I've missed this in the FAQ, user's manual, or (poorly searchable)
archives, please point me to what I've missed.  

In a shell buffer in NTEmacs configured per the shell-setup instructions 
in the CygWin FAQ at http://sources.redhat.com/cygwin/faq/faq.html#SEC5 , 
control-C doesn't seem to work.

That is, typing two control-C's in Emacs (to send a control-C to bash) 
doesn't kill a long-running command (e.g., like "du /" or "sleep 10").  

Emacs does seem to flash the window title bar, but I can't tell what it's 
trying to indicate.  Does this seem to be an NTEmacs/CygWin interaction
problem, or just an NTEmacs problem (not for the CygWin list)?

Is control-C still supported in CygWin and between NTEmacs and CygWin?  (I 
just upgraded from CygWin B20 (or so), and not yet used to how things work
now.)

Thanks,
Daniel

This bites me several times a day.  It is a known problem, but I don't
know what the status on a fix is.  I will be very glad to see it.

Do you mean it's a known problem that crops up (for some people), or that
it simply doesn't work at all (for anyone combining Emacs and CygWin)?

I don't know the full answer to that.  For me, certain shell processes
will die with ^C, some will not.  I can kill "java", but I can't kill
"tail -f" or "perl" (I have to use Task Manager).  I have seen other
people report this.

Recently?  Daniel's was the first report of this I've heard in months at
least (longer than that most likely but I tend to be conservative when it
comes to my memory).  I might be wrong but I don't think this is a known
problem and its certainly something that I don't see.

Earnie Boyd indicated on 9/26 it was "fixed in snapshots", but I've
never seen any mention of a released fix for it.  I recently upgraded
my cygwin (1-2 weeks ago), so if the fix was there, I should have it
(but I don't).

I just upgraded yesterday or Wednesday, from the ftp.sunsite.utk.edu mirror
(and the latest Emacs as of yesterday or Wednesday).

Hm, I don't know why you have this problem but I can say that you have the
fix Earnie was referring to.  Anything in the nightly snapshots as of 9/26
would be in the current 1.1.7 "release", if not the 1.1.6 and 1.1.5 
"releases".  So it may be related but the problem is certainly different.

Hmm.  I think I've seen Java behave differently, but in the opposite
direction.  On my _old_ setup (Emacs ? with CygWin 20 or so), java (Sun's) 
would sometimes print out some status dump when I tried a control-C.  
I think Java specifically catches an alternate signal (SIGQUIT? on Unix,
something else on Windows) to do that.

Maybe Emacs and/or CygWin are sending different signals at different 
times or under different configurations, or processes are vulnerable
to different signals under different conditions.


AAAAGGGGHHHH!!   Reinstalling a machine's worth of software is bad
enough without failures between critical areas (for me) like Emacs and 
Unix commands.

I think he meant it is a general problem for everyone. The base of this
is that the emacs shell buffer is not a tty. You can check it by doing
`stty', you'll get: "stty: standard input: Not a character device".

And hence, it is not a tty ==> it will not generate SIGINT for ^C.

Ehud.

Forgive me for coming late to the party.  I didn't digest that this 
conversation was about NTEmacs (i.e. the Windows port).  I'll leave 
aside whether or not ^C should work in this context.  I really don't
know whether it should/would/ever did.  I don't use Emacs.  However, 
I can say you'll have better luck with a Cygwin version of Emacs, like
XEmacs.  You'll find Cygwin applications work much better with other 
Cygwin applications, especially in areas of detail like this.

YMMV.  Void where prohibited.

How different is XEmacs from GNU/NTEmacs?  

(I don't do much (any) Lisp programming, so I guess I'm just asking about 
default configuration and about compatibility of add-ons like JDE.)

Sorry, I was a little unclear.  AFAIK, there is a Cygwin version of XEmacs
but there isn't one for NTEmacs.  My main point was that signal functionality
can be handled by Cygwin (and is) or by the O/S.  However, the signal coming
from a Win32 app doesn't get the same response out of Cygwin as one coming
from a Cygwin app.  If you have problems in this area, your best bet is to 
use Cygwin-enabled versions of apps when available.

I just meant how different is XEmacs from NTEmacs to the user?  If I switch 
from NTEmacs (which I'm used to) to XEmacs (which I don't know), how big a 
change is that likely to been (from the Emacs user point of view)?

I, of course, am not qualified to answer that question since I don't use
Emacs at all.  Others might be able to help.  You may be better off asking
this question on some Emacs list though...

I've done the switch a long time ago. NO big deal.
Just switch of the toolbar and it feels like Emacs.

Which of cygwin32's design goals does ascii file conversion fulfil?

[David Fox]

As I have noted before, there are two types of cygwin32 users, those
who are trying to make their Windows box feel more Unixy, and those
who are porting Unix code to Windows.  It seems to me that neither of
these groups has any need for DOS ``text mode'' conversion (where
lines are terminated by CR-LF.)  Why not make binary mode the one and
only default once and for all?

There's probably a good reason that I'm not aware of...

The question as spelled out in the subject line is of course important. The
discussion of text vs. binary is not very productive, unless one states the
intention of providing the cygwin package.

I can see two camps around:
- those that want a Unix to run on the hardware that typically supports a
Windows system. But wouldn't it be better to go for a Linux, FreeBSD, NetBSD
or something like that. I.e. a true Unix system

-those that want Unix functionality to gracefully coexist *and_cooperate*
with functionality provided by a Windows platform. This cannot be provided
by a Linux at al. solution

Cooperation between Unix functionality and Windows functionality has two
implications: (a) to be able to share data between these two goups of
functionalities (i.e. programs) without necessarily bothering about
representatiuonal issues, and (b) to be able to have programs of the
different groups interact "seamlessly".

Enforcing a binary approach to data in Cygwin applications would make it
difficult to fulfill either of these two goals. Imagine using Netscape as a
browser and wanting to have Cygwin-based applications handling some types of
documents. If such applications could directly handle native Windows
representations, it would make life much more simple.

My understanding has been that Cygwin tries to achieve the "peaceful
coexistence and cooperation" goal. If Cygwin tools require a full binary
mount, then we do have some problems in achieveing the goal.

So, what are the Cygwin design goals really? Are we hoping for something
that cannot be fulfilled?

Or is it, as some have suggested, not the design goals of the Cygwin
infrastructure that is limiting us. Is it the design goals of the tool
porters that might restrict us?

This is the primary goal.  In my personal uses of Cygwin, I have never
needed to use binary mounts.  Instead, I have added the requisite
binary mode flags to open calls, etc.  Usually, it's not very
difficult.  Some of the text utilities that should be able to be used
in either text or binary mode still need binary flags added though,
that's about has hard as it gets (still not very)...

Ernie Boyd has written at length describing the typical changes to get
everything working correctly with text mode mounts (a version of which
will appear in the upcoming b20 FAQ) so I won't repeat it here.

I'm trying mingw to see if it's a viable alternative to Visual C++.

The main reason is writing a program that has to read or write files that
have to be used on Windows.

Actually I see you're just referring to what the default should be. I
always explicitly define "b" or "t", but I wonder how much existing code
would break if the default changed?

My point is that you either disallow discussion or you allow it.
Saying "It's ok to post but nobody follow up!" is fairly unusual
for a mailing list.

It's usually "This is off-topic" please don't do that again.

The first way you get to (potentially) correct one person.  The second
way you get to correct many people.

Re: problems with less

[John S Cooper]

I think the display problems I was having with `less' disappear when I do the
following:

  1. Set TERM=cygwin rather than TERM=linux.
  2. Don't use `less -r' as an alias for `less'.

Perhaps this is something for a README/FAQ?

So, if you don't go out of your way to use less in a non-standard way, it
works fine.  That doesn't seem like FAQ material to me.

The man page for 'less' says '-r' causes the program to output ASCII
control characters found in a file as the control character rather than
a symbol sequence like '^A', etc.  This is a standard documented
feature.  What was missing in this case was an understanding of what
this means to the terminal emulator.  For instance, if a <CR> (^R) was
embedded in a line, the remainder of the line would overwrite its
beginning.  If there is a form feed (^L if I remember correctly), the
screen might be cleared (depending on the TERM type, of course).  And so
on.

I agree that this is not a FAQ item.  The feature is already
documented.  It just requires a little analysis and thought, to
understand the potential consequences.

[PB] "no acceptable ld" : cywin32 pb, way to handle win path ?

[Sebastien Barre]

Here are some excerpts of a problem discussed in the cywin32 mailing list.
I thought it might be interesting for the automake people too (this message

http://www.cygnus.com/ml/gnu-win32/
http://sourceware.cygnus.com/ml/cygwin/1999-02/msg00702.html

It seems related to the way configure script handles path (many of use
encoutered the pb with different configure scripts) :

strange mount behaviour...

[Sebastien Barre]

Well, sorry to post another naive question, but here is a sequence of
reproducible commands that lead to something very obscure to me : mounting
D: (the disk where cygwin and my root is located) seems to invalid some
internal behaviours (well, let's say some illogical things appear :)

Here it is. I just installed B20.1,

> GNUWIN32=d:/devel/gnuwin32; export GNUWIN32
> CYGROOT=${GNUWIN32}/cygwin-b20; export CYGROOT

- create some directories for a kind of filesystem

> cd ${GNUWIN32}
> mkdir root
> cd root
> mkdir tmp etc d

- mount

> umount /
> mount ${GNUWIN32}/root /
> mount D:/temp /tmp
> mount ${CYGROOT}/etc /etc

No pb until now, for example, let's have a look at /etc (two times)  :

> cd /
> ls
d/ etc/ tmp/
> ls etc
termcap
> ls /etc
termcap

Now here is the funny part :

> mount D: /d
> ls etc
> ls d 

!! nothing !!

> ls /etc
termcap
> cd /etc
> ls
termcap

!! now here they are, '/etc' works, 'etc' does not !!

> cd ..
> ls d
> ls /d
autoexec.bat config.sys
... etc.

Could anyone explain me why mounting D: ou D:/ ou d:/ to /d produce these
artefacts ? Doing the same thing with C: ou E: will NOT cause any problem.
Is it impossible to mount the drive where cygwin is located ? Installing
coolview did not help too. As well as binary mount.

Thanks

It is a good idea to check (and paste it with the other things) what
your pwd is here. Just to be sure :)

To avoid problems, you shouldn't mount directories from the same
partition, if it isn't absolutely nescessary.
Instead use

Device                       Directory     Type        Flags
D:\devel\gnuwin32\cygwin-b20 /             native      text!=binary

and then
ln -s //d/temp /tmp

and use //d/ instead of /d

internal behaviours (well, let's say some illogical things appear :)

Here it is. I just installed B20.1,

> GNUWIN32=d:/devel/gnuwin32; export GNUWIN32
> CYGROOT=${GNUWIN32}/cygwin-b20; export CYGROOT

- create some directories for a kind of filesystem

> cd ${GNUWIN32}
> mkdir root
> cd root
> mkdir tmp etc d

- mount

> umount /
> mount ${GNUWIN32}/root /
> mount D:/temp /tmp
> mount ${CYGROOT}/etc /etc

No pb until now, for example, let's have a look at /etc (two times)  :

> cd /
> ls
d/ etc/ tmp/
> ls etc
termcap
> ls /etc
termcap

Now here is the funny part :

> mount D: /d
> ls etc
> ls d 

!! nothing !!

> ls /etc
termcap
> cd /etc
> ls
termcap

!! now here they are, '/etc' works, 'etc' does not !!

> cd ..
> ls d
> ls /d
autoexec.bat config.sys
... etc.

Could anyone explain me why mounting D: ou D:/ ou d:/ to /d produce these
artefacts ? Doing the same thing with C: ou E: will NOT cause any problem.
Is it impossible to mount the drive where cygwin is located ? Installing
coolview did not help too. As well as binary mount.

Thanks

Cygwin commands crashes after ssh login

[Christer.H.Jansson]

I have Windows NT4-SP6+different security patches box with latest 
cygwin/openssh versions.

When logging in with ssh (Yes, I have tried different clients) first of 
all id.exe crashes. After confirming Dr. Watson message on console I 
get logged in. If I try cygwin commands (id, hostname, ls, ps...) I get 
Dr. Watson crash. However I can still run echo and pwd commands.

I have tried re-installing several times. Both on NT Server and 
Workstation.

Is this a known problem? I have seen someone writing about id.exe crash 
problem before.

If I change to older version cygwin-1.1.5.7 everythings works nicely.

I can provice Dr. Watson logs if needed.

Re: Cygwin commands crashes after ssh login

[Erdely, Michael]

I've noticed this a lot.  With Windows 2000 Pro and Server, with and without
SP1, as well (so it's not the specific version of NT/2000).  I've also
noticed this when running sshd as part of inetd (running as both a specific
account & SYSTEM) and with srvany (running as both a specific account &
SYSTEM).

So far, switching back to Cygwin DLL version 1.1.5-7 is the only solution
I've found.

One thought I had after reading
http://cygwin.com/ml/cygwin/2001-01/msg00714.html was that it may be a
problem with BASH and not with Cygwin.  So, I was wondering if anyone who
_IS_ having this problem is _NOT_ using BASH as their shell in /etc/passwd.
Also, if anyone is _NOT_ having this problem and _IS_ running BASH as their
shell in /etc/passwd.  If you fall under the previous two categories, how
are you running SSHD (SRVANY, INETD, specific account, SYSTEM, CYGWIN=ntsec,
. . .).

Personally I'm using tcsh and bash as login shell. I'm using W2K SP1
with Cygwin 1.1.7, sshd is started via SRVANY under my own account
which has the appropriate user rights and I don't have any problems
using ssh and sshd on the box. For testing purposes I'm sometimes
switching to starting sshd from inetd using LocalSystem account and
password authentication. No problem at all.

I'm really sorry but I don't know what I can do as long as I can't
reproduce any of the described effects.

Re: Cygwin commands crashes after ssh login

[Erdely, Michael]

Just curious, Corinna, but have you tested this on many machines?  I'm
curious as to whether you are testing on your development machine.  I've
installed and experienced this behavior with fresh installs, existing
machines, Cygwin upgrades, . . .

Have you tried a fresh, out of the box, Cygwin install and see how it
behaves?

Just curious.  I'm trying to find some commonality between machines that
exhibit the bad behavior and those that don't.

-ME

PS: I'm not being critical in the least here.  The Cygwin team, and with my
interest in SSH, especially you, Corinna, have my complete and utter
gratitude and respect.  I'd love to be more adept at programming to be able
to contribute to the projects.  Thank you for your hard work.  It is
definitely more than appreciated.

As someone else struggling to help solve this, first can I warmly
endorse Mike's kind words -- you've been tremendously helpful, that's
why we're frustrated your efforts on this one issue have so far been
in vain.

Following up on one tiny part of the above, when you say '... from
inetd _using LocalSystem account_', what does that last bit mean?  I
don't have a LocalSystem user in either /etc/passwd or Win2K Users. . .

I believe Corinna is referring to the System account on your local machine
(i.e. not on the domain).

I have exactly the same question.  Would someone please post a more
pedagogical procedure of creating the LocalSystem account in W2K?  Unlike in
the case of NT4, I found no place to specify any "special rights" for the
user.  I have been trying to make OpenSSHD work (for a multi-user
environment started from inetd) for a week and have not gotten anywhere (see
the following error message produced right after keying the password.)

www.google.com seems to be very chatty on the subject of "LocalSystem".

LocalSystem == SYSTEM.

Nothing to create. SYSTEM already exists. It never shows up in any
user management console.

It's a MMC snap-in. There are three of them for local, domain and
domain controller rights.

What's this?  Actual information from someone who has *debugged* the
problem?

Surely you meant to say something like "I know, I can't even use
CTRL-C!  What's up with that?  I had to drop back to B19!"  Mentioning
low level things like the "sigcatch" semaphore is way too much info.

You're starting a dangerous trend, Egor.  Watch out.

it  turned  out  that  i've actually skipped  the  most important part

Hmm.  We're in the slow process of moving sources.redhat.com to a T3.
Maybe that would be just the impetus we need to finally finish the

Works for me but my account used for starting sshd is in the local
admin group. Could you test this in your environment, too, and
report if that solves your problem?

Uh,   you're  right. i was starting inetd from non-admin account. after
restarting it from any admin account everything works fine.

i've  just realized that doing otherwise, cygwin would allow one process
to  send  signals  to  other  process  started from different account.
unices don't allow this, and neither should cygwin.

i think you can add something like this to README file

== openssh-*.*.*.README ==
...
- If you want to be able to login to different user accounts you'll
  have to start sshd under system account or any other account that
  is able to switch user context. Note that administrators are _not_
  able to do that by default! You'll have to give the following
  special user rights to the user:
  "Act as part of the operating system"
  "Replace process level token"
  "Increase quotas"
  and if used via service manager
  "Logon as a service".

+  This user should also be a member of local "Administrators" group.
...
==========================

or   "we   recommend   you   to   make  this  user a member of  local
"Administrators" group, otherwise Ctrl-C won't work!" :-)

tcsh Win2000: command line editing does not work

[Brad Barber]

[Expanded version of previous message.  No reply to the first one.]

I've recently installed cygwin and the cygwin version
of tcsh on a new Windows 2000 computer.  It is a big 
improvement over the older version of tcsh (the one not 
bundled with cygwin).

Everything works well except for command editing.  If I insert
characters, the display overwrites and occasionally shifts right.
The underlying data is correct (i.e., the characters are inserted
into the line).   Command editing works fine with the bash
shell.

For example,

KANE:/home/bbarber> 123456789

if I insert "a" between the 1 and the 2, the "3" is overwritten

KANE:/home/bbarber> 1a2456789
1a23456789: Command not found.

But if I insert "a" between the 5 and the 6, I correctly get

KANE:/home/bbarber>  12345a6789 
12345a6789: Command not found.

It fails to work without any .tcshrc defined.  It also fails to work
on a friends Win2K system.  Unfortunately, it fails to work
most of the time.

I checked stty.  It leaves "echoe" and "echoctl" while bash turns
these off.  "stty -echoe" does not change the flag.

Any ideas?

Sure. It's a known problem. It only happens in a console window, not
in xterm or other tty/pty connections.

Patches (probably to the Cygwin console code) welcome.

Tcsh uses the insert mode in the terminal capability.  Cygwin
console doesn't support it, nonetheless the termcap database
tells it supports the insert mode. Therefore this problem can be
solved by modifying the database as the following.

I believe it is hard to implement the insert mode in the Cygwin DLL.

Is there a corresponding change I can make to .cshrc?  If not,
please let me know where the database file is.

Another display problem:

I noticed that new text is not automatically displayed at the
end of the display buffer.  For example, if I scroll back and then 
type 'Enter/Return', it displays the command prompt in the bottom
of the currently display page.  It should move back to the end of
buffer, and display the prompt on the next (blank) line.

Thanks for your help.
                                                        --Brad

P.S.: Does any one know of a converter for .cshrc to .zshrc or .bashrc?
I'd like to have one initialization file that I can deploy under multiple
shells.

You can modify the existing entry in /etc/termcap,
or create ~/.termcap and insert this entry.

It should be fairly easy to do this.  There is a Windows API that 
can accomodate horizontal scrolling, I think: ScrollConsoleScreenBuffer.

It is

as installed with the most recent
        Cygwin setup.exe

P.S.: i was mistaken about stty.  Both bash and tcsh return the

Well, if I could find the equivalent to getopts, I think I could
get along without kornshell.  I found this feature to be
extremely useful when I was a heavy-duty KSH programmer, and now
I am coding a few scripts again and would like to take advantage
of it.

pd-ksh doesn't implement them either.  It attempts to emulate ksh88, with
a few ksh93 features that POSIX specifies.

The ksh88 and ksh93 features that bash does not implement (with suggested
bash equivalents for a few) are listed in the FAQ.

[ANN] PW32 the (alternative) Posix-over-Win32 layer 0.3.0 released

[Paul Sokolovsky]

Hello cygwin,

      I would like to introduce to gnu-win32 community new (yet
another) POSIX "emulation" layer. It is product of some thoughts and
ideas that were spoken, and sufficiently criticized, on cygwin list.
Standard description follows:

"PW32 is implementation of (subset of) POSIX/Unix API for Win32 systems. Its main
concerns are efficiency and full platform coverage, including adequate support for low-end
Win9x systems. PW32 is based on DJGPP's runtime library by DJ Delorie. PW32 is licensed
under LGPL."

      PW32 is only month on public, but before that it was more than
year in development. That means it'd already has something to show,
though of course it's far from being complete. Also, as I hinted above,
it's based on solutions that might be considered questionable, if not
orthodox. Even besides that, I claim that their sole purpose is to get
rid of mean, chore problems plaguing existing implementations, and to
get efficient implementation. So, I took steps to describe these
traits, and provide means of coping with them and integrating with
"native" environment.

0.3.0 is second public and first 'full-fledged' (as for alpha)
release. Changes include:

* Many bugfixes.
* Tested and runs on 9x and NT. On 95, problems known and identified,
with workarounds provided.
* Binaries provided: build environment based on gcc-2.95.2-1-mingw32
(courtesy of Mumit Khan), ash, fileutils, textutils, sed, grep,
sh-utils, diffutils, make.
* Updated documentation.

  Also, PW32 is currently in active development, for example, now
two serious problems with 0.3.0 had been fixed (and available from CVS).


PW32 is hosted on SourceForge, http://pw32.sourceforge.net/

Place to discuss PW32 is mingw32 mailing list,
http://www.egroups.com/list/mingw32

Hmm.  I would like to receive opinions on whether people consider this
announcement to be off-topic.

We don't see any DJGPP announcments here.  We don't see any UWIN or Interix
traffic.  Maybe I'm wrong, but I don't think that Mikey announced here, either.
(How's that for giving a plug to all of cygwin's competitors?)

I don't think that announcements of (alternative) Posix-over-Win32 layers are
on topic here but if everyone else disagrees, my opinion can be changed.

    I greatly appologize! I wanted to include these possible
appologies in original announcement, but just thought: after all, we
all doing same thing, namely gnu-win32 (btw, isn't that trademark of
Cygnus, the Red Hat company?). While this list is of course dedicated
and owned by cygwin, it's de-facto mother list of all
Unix/Gnu-on-win32 lists, and have grown others (such as mingw32) off
itself. I also think my little stuff indebted to cygwin by its birth,
and hoped I could use that wonderful possibility - to announce it
once, and rejoice cygwin people with that announcement. And of course, my
little stuff is not competitor of cygwin (competitor? ridiculous. have
years of work of many people were put into it? does it offer that level
of support?), but rather an (spiritual) offspring targeted at niche
intentinally left out by cygwin. After all, that's what free software
is all about.

   I once again would like to say that was one-time announcemnt for
information of gnu-win32 comminity. Under no circumstances I planned
to continue that announcing or start discussions here. If even that
was illicit, I would like to ask pardon from all cygwin community.

  Thank you for your support.

Don't know, what you mean by reliable, but you can get the
sharutils-4.2c package, which contains uuencode/uudecode among other
utilities
     - on ftp.franken.de
     - in /pub/win32/develop/gnuwin32/cygwin32/porters/Hirmke_Michael/B20

These just don't work at all:

  $ cp c:/WINNT/NOTEPAD.EXE n.exe
  $ ./n.exe      # works fine!
  $ uuencode n.exe n.exe > n.uu
  $ rm n.exe
  $ ls n.*
  n.uu
  $ uudecode n.uu
  $ ls n.*
  n.exe*  n.uu
  $ ./n.exe
  zsh: exec format error: .\n.exe
  $
  $ ls -l n.exe
  -rwxrwxrwx   1 JCooper          Domain_Users      594 Jan 18 10:37 n.exe*
  $

Any ideas what's wrong with it?

Let's stop this uuencode/decode discussion.
Here are two small little programs in that old but powerful language we all

------------------------------------------------------cut here: uuencode.c
#include <stdio.h>
#define ENC(c) ((c) ? ((c) & 077) + ' ': '`')

These also don't work (see below).

This doesn't look like a "mount" problem?  The cygwin FAQ states about mount:

  "The '-b' option to mount mounts the mountpoint in binary mode where text and
   binary files are treated equivalently. This should only be necessary for badly
   ported Unix programs where binary flags are missing from open calls."

... and your code does open the files in binary mode, so shouldn't it work
regardless of mount?

It even seems to fail when I do mount a directory in binary mode...

If nobody has a solution, I guess I'll try debugging it when I get time.

Oddly, if I use the combination of the sharutils uuencode.exe and the
uudecode.exe that I compiled from the source posted here, it works.

Other combinations don't seem to work...

I've also hacked the uudecode source to read from stdin when given no args, so
I can use uudecode.exe with Emacs' call-process-region.  At last uuencoded
attachments from Outlook can be quickly decoded from pGnus!

This source simply doesn't work for me - it generates all sorts of different
characters at the beginning of encoded lines, rather than the "M" that I see
with most uuencoders.

I finally pulled over the sharutils-4.2 source, got that to build under NT and
then carefully enabled (or disabled) the binary flag on the fopen calls.  It
now seems to work fine - without mucking with mounts or using bash (I prefer
zsh).

Thanks for all the ideas...

Re: uudecode?

[Pierre A. Humblet]

This has taken enough bandwidth that we might at least understand what
happened.

As stated in their README, the shareutils from ftp.franken.de require
binary mount. On a text mounted system the uuencode INPUT file gets
truncated at ^Z.
Ideally uuencode should binary open its input file AND setmode stdin to
binary (for use with cygwin shells, other shells always open stdin binary).
Similarly the output of uudecode should be binary.

It doesn't matter if the output of uuencode and the input of uudecode are
text or binary. Those programs encode the line length, usually taking in 45
characters at a time (they have to, to survive inclusion in e-mails).
uuencoded lines start with M because M is the 45th printable character
(above " "). Those 45 characters are expanded to 45 * 8/6 = 60 characters
per line, plus the length.

The uuencode.c program contributed in
http://www.cygnus.com/ml/gnu-win32/1999-Jan/0493.html has a bug: the first
ENC(ch) should have been ENC(n). That's why the uuencoded lines did not
start with M.  
There is also a bug in uudecode.c
if (!strncmp(buf, "end\r\n", 5))
will fail when the file ends with "end\n". The bug is not exposed because
the program normally terminates at the next to last line, which has zero
length.

Try sharutils-4.2 from http://www.gnu.org/software/software.html

It compiles out of the box.

long long vs long

[Graham Murray]

This is probably a silly question, but rather than having long long for
64 bit, why was long not made 64bit? The standard (AFAIK) states that
short <= int <= long.  So, it should be possible for long to be 64 bit
rather than 32. This would give a simple progression from 8bit chars to
64bit longs.

   This is a frequent question.  I am told that while it would
be thoreticaly a good idea, so much existing code would break as
to make it unviable.  (This from a member of the C9x committee.)

	Unfortunately the standard also specifies the length of several
types.  Specifically char is 8 bits, short is 16 bits, and long is 32 bits.
The int type is NOT a specific length but is platform dependent, so an int
on earlier (XENIX and MS-DOS) systems use to be 16 bits while on modern
systems it's 32 bits.  Specifically, an int is defined as the "native"
integer number representation.  Of course, all of these types are "signed"
and have "unsigned" equivalences.  And before have the list jumps on me,
yes I know that unsigned and signed char's get into some interesting
ambiguities, particularly with old code that assumed that a char was
unsigned...

	Most code uses "int" where it wants the native number
representation.  That same code uses "short" and "long" where it wants
specific field lengths.  Imagine the havock that will transpire in code
with masks such as "foo = bar & 0xffff0000L" if you were to expand
long to be 64 bits.  The porting nightmare would make a sequel to
"Nightmare on Elm Street".

  Really?  Can you give the paras where it does this?  AFAIK
short, int and long are nowhere defined in length.

Not to be picky, but to quote K&R II pg. 36:

"Each compiler is free to choose appropriate sizes for its own hardware,
subject only to the restriction that shorts and ints are at least 16
bits, longs are at least 32 bits, and short is no longer than int, which
is no longer than long."

Also, chars are not limited to be only 8 bits, but they must be at least
8 bits.  I routinely work on processors (C40, C44) where CHAR_BIT is
32.  This results in the pecularity that 

	sizeof(char) = sizeof(long) = 1

which is perfectly legal.  I think there is a lot more code in the world
that asumes that CHAR_BIT is 8 than sizeof(long) is 4.

The standard says no such thing.  In section 5.2.4.2.1 Sizes of integral
types <limits.h>, it says

        The values given below shall be replaced by constant expressions
    suitable for use in #if preprocessing directives....  Their
    implementation defined values shall be EQUAL or GREATER [emphasis
    mine] in magnitude (absolute value) to those shown, with the same
    sign.

    -- number of bits for smallest object that is not a bit field (byte)
       CHAR_BIT				8

    ....

    -- minimum value for an object of type short int
       SHRT_MIN			   -32767

    -- maximum value for an object of type short int
       SHRT_MAX			   +32767

    ....

    -- minimum value for an object of type int
       INT_MIN			   -32767

    -- maximum value for an object of type int
       INT_MAX			   +32767
  
    ....

    -- minimum value for an object of type long int
       LONG_MIN		      -2147483647

    -- maximum value for an object of type long int
       LONG_MAX		      +2147483647

The first paragraph clearly states that these values are implementation
defined and that the sample values are suitable minimums.

Furthermore, in section 6.1.2.5 the Standard states, "There are four signed
integer types, designated as signed char, short int, int, and long int."  It
then goes on to say, "In the list of signed integer types above, the range of 
values of each type is a subrange of the values of the next type in the
list."

In other words,

    sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long)

and

    sizeof(char)  == 1
    sizeof(short) >= 2
    sizeof(int)   >= 2
    sizeof(long)  >= 4

While I agree that there is a large body of code that assumes long is 32
bits, such code is not portable.  And not because of a flaw in the Standard,
but because the programmer(s) responsible either didn't know the above or
didn't care.

Not necessarilly.  By definition sizeof(char) is always 1 no matter what
CHAR_BIT is defined to be.  But the values for the other sizeof's are
not correct for all machines.

For example, on the TMS320C3x and TMS320C4x families, the minimum
addressable memory unit is 32 bits, so CHAR_BIT for this machine is 32. 
It also happens that all other intergral types (short, int, and long)
are 32 bits (the exact size of char), so

sizeof(char) == sizeof(short) == sizeof(int) == sizeof(long) == 1

Weird, but legal.

Sorry but this doesn't seem to follow.  I agree with the interpretation of
the standard, namely:

  sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long)

However, this does NOT imply what follows (the sizeof lines after the "and".)
The implication from the standard is:

  sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long)

AND

  sizeof(char)  == 1
  sizeof(short) >= 1
  sizeof(int)   >= 1
  sizeof(long)  >= 1

which someone on this list pointed out previously.  I think the key words 
here are that "the range of values of each type is a subrange of the values 
of the next type in the list."  Are we getting a little too far off topic 
for this list?

This follows from the earlier section of the standard I posted which states
the minimum ranges for each type, namely -127 to +127 for signed char, -32767
to +32767 for signed short, etc.  These imply that char is at least 8 bits,
short is at least 16 bits, and int and long are at least 32 bits.  Assuming a
char is exacly eight bits (it's not clear to me whether the standard requires
that or not) it follows that:

    sizeof(char)  == 1
    sizeof(short) >= 2
    sizeof(int)   >= 2
    sizeof(long)  >= 4

As to whether we're getting off topic.  Clearly this group is about
portability and I was disturbed by the number of misinformed posters

No, it only specifies the *minimum* ranges that each type must cover and
it gives some relations like all values representable by "short" must
also be representable by "int" and "long" etc. The net result for most
current architectures are the conditions (I hope I don't miss anything
important)

  sizeof(char) == 1  // that's a definition actually, not a condition
  sizeof(char) * CHAR_BITS >= 8
  sizeof(short) * CHAR_BITS >= 16
  sizeof(int) * CHAR_BITS >= 16
  sizeof(long) * CHAR_BITS >= 32
  sizeof(int) >= sizeof(short)
  sizeof(long) >= sizeof(int)

The language standard does not say that "int" must be similar to one of
"short" or "long", so an implementation that does

  sizeof(short) * CHAR_BITS == 16
  sizeof(int) * CHAR_BITS == 32
  sizeof(long) * CHAR_BITS == 64

is prefectly comforming.

The main argument for a new type "long long" as I understood it in the
Newsgroup discussions was that there was just too much code out there
that relies on binary compatibility for the "long" type. A compiler that
wants binary compatibility *and* a 64 bits type must introduce a new
type.

One argument against was that the current standard guarantees that
"long" is the type with the largest range of them all. This makes code
like this legal and portable:

  size_t size = sizeof(someobject);
  fprintf( somefile, "%lu", (unsigned long) size );

with the guarantee that the cast will not truncate the value. The new
type can change this code without warning, because with a new type
size_t might be an alias for "long long" instead of maximally "long".
This was probably considered a rather obscure point by some. But than I
sometimes feel like portability issue often are about rather obscure
points, which is probably why they get missed so often.

I can only recommend to search the comp.std.c newsgroup for the topic in
Dejanews.

Several reasons, actually.

Technically, it doesn't make sense, at least in the PC world, where
all processors are <=32bits.  Any 64-bit operation takes 2 separate
accesses and math, etc., becomes more complicated (and requires more
instructions and time).

Probably the more pervasive reason, however, is that there exists A
LOT of code out there which expects sizeof(long)==4.  It's sort-of an
un-official C standard.  In particular, legacy code dealing with
networking, etc., is frequently very loaded with such assumptions.
IIRC, the original CRAY C compiler used a 32-bit long and a 64-bit
int, just because so much code had this expectation.  IMHO: C should
have included standard data sizes, as well as it's generic types.  It
would have made many things a lot simpler.

Just my $.02 worth.

No because the standard says
short == 16 bit
long  == 32 bit
int   == 16 or 32 depending on the machine's architecture

For example: Under DOS int is 16 bit while under Win32 und UN*X it is
32 bit.
So there's no way for long to be 64 bit while conforming to the
standard.

Suggestion: Add "Re: long long vs long" to your kill file or filter or
whatever you use. Alternatively consider deleting anything with that subject
without reading. I measured the time on my keyboard for deleting similar email
messages. Using vm under emacs I was able to delete in an average of .3
seconds per message if I did not bother to read the message. That's frankly
what I do with 95% of the traffic on this list. If it takes you longer I
suggest changing mailers. 

Also I have found that not reading mail makes it impossible to be annoyed by
the innanity of that mail because I cannot then tell if the mail is innane or
not. Fortunately I have never seen a mailer that forced me to read mail on an
uninteresting topic.

In other words I suggest you lighten up. This is a support group, not a
private list for insiders. Since gcc supports "long long" the argument could
be made that this is a vaguely on point topic. I could also make an arguement
based on its relatedness to portability. Less on point topics have been
discussed here without complaint.

As long as there is resistance to turning this list into a newsgroup where it
would be easier to split into subgroups then I have little sympathy for
complaints about off point discussion. Since this is the only forum for
discussing cygwin related stuff we shouldn't be too restrictive about how
closely related the discussion must be.

I agree with whoever posted this.  The "long long" topic has very little
to do with gnu-win32.  When a message thread starts moving outside of
the purpose of a mailing list, the polite thing to do is to move it
elsewhere.

Resistance?  Where is there resistance?  If you'd like to spearhead the
campaign to turn this into a newsgroup, please feel free to do so.

The fact that this is not a newsgroup is one more reason why off-topic
threads such as this one should be squashed.  Some people who are
subscribed to the gnu-win32 mailing list are actually paying for their
connections.  There's no reason for such people to pay for "long long"
discussions.

Okay, got me. As I've never seen a system that uses longs with more or
less than 32 bits I simply thought that it's pretty useless to argue
about whether the standard says this or that when nearly all code
relys on that fact. But after reading this thread on the list it seems
to me that there are even a lot systems with incredibly long longs and
so I now think you're right. ;)

In defense of the original poster, this is not splitting hairs.  You yourself 
invoked the _Standard_ to assert:

    1.  short is 16 bits and long is 32 bits
    2.  a conforming implementation cannot use a 64 bit long

Both statements are incorrect and such commonly held misbeliefs are a
frequent source of portability problems.  Since this group is very much about
portability, its important not to spread misinformation where portability is
concerned.

BTW, I'm not speaking from an "Ivory tower".  I recently had the job of
porting an application from NT to Digital UNIX with, you guessed it, 64 bit
longs.  The code is full of assumptions that a short is exactly 16 bits and a
long is exactly 32 bits.  Furthermore, the programmers never use int because
they don't know its size.  Needless to say the port was costly.  So, you see,
such distinctions do matter.

Okay okay, I said Jehova and now everyone is throwing stones at me. ;)


I now know that my statement about the standard was thoughtless,
sorry. In my little world I thought that longs are 32 bits and that
almost all code relys on this. I simply didn't know about the world
around my little universe. :)

So sorry and till the next mindless mistake...

Hmmm. I don't have a copy of the standard laying around, but I do have
Kernighan & Ritchite (2nd ed.) which says

Section 2.2:
...
Each compiler is free to choose appropriate sizes for its own hardware,
subject only to the restriction that shorts and ints are at least 16
bits, longs are at least 32 bits, and short is no longer than int, which
is no longer than long.

You're right, it is a silly question.  ~:^)  I did a lot of 64bit unix
kernel porting work a few years back, and the reason that something
other than 'long' had to be used is that there is about 6 trillion lines
of C code in the world that would seriously break if long's suddenly
became 64 bits, because coders have been using 'long' for more than a
decade with the belief that they are the same size as 'int'.  Avoiding
the discussion of why they didn't use 'int' all those times, suffice it
to say that a new type was created for the sake of expediency.  Everyone
who has written code that might require some fixin' if long's changed to
64 bits, raise your hand.

The irony is that types like 'long long' are usually accomplished in
some basic header, not as a base compiler type.  The base compiler 64bit
types are almost always of the form '_int64' or some such.  It seems we
just can't ever separate int's and long's!

Yes, I realize that.  But it seems like there are some concessions being
made to the folks who claim that the tools ought to interoperate more
easily with the DOS tools (e.g. accepting file paths like "c:/windows").
So, I keep hoping that someone will come up with some clever scheme to do
away with this text=binary mount stuff (which seems to be one of the most
awkward things about trying to use the gnu-win32 stuff).

I keep hoping to be able to find some affordable (read: negligible
monitary cost :-)) alternative to MKS sh (or whatever) to give me a Unix
toolset that can interoperate with the Windows developers and development
tools that I need to.

Re: Why text=binary mounts (Re: Gnu-win32 (b18), coolview and NTEmacs)

[Jeffrey C. Fried]

Porting code from Unix to the PC should NOT require the same line
termination mode since most Unix code which reads text uses fread/getc
which automatically handle the end-of-line.  And from the replies of most
people i would argue that most of us would prefer to work in the native
mode of the operating system in which we are running rather than having to
constantly convert files between the two models simply because we use tools
from both operating systems under NT/95.  For examples of this
compatibility look at many of the GNU tools which handle text, the file
handling will work under both operating systems without any change because
they use text mode I/O which is platform independent once all files have
been converted to the form of the native OS.

A problem is that the open() call in MS-land has a binary/text mode flag,
but Unix open() calls generally don't (since there is typically no
binary/text mode distinction made).  So, you always end up having
problems with porting arbitrary Unix code over to MS-land when the Unix
code calls open() without specifying a mode AND the default mode doesn't
match what the Unix code was expecting.

Part of the problem with specifying the default text file type on a
per-mount basis is that it frequently isn't the right basis for specifying
it.  I may have mounts where I want both style of line termination - maybe
it's more related to what kind of file I'm writing.  Using the mount point
is kind of a best guess heuristic, I guess.  What we need is omniscent
software that just knows what I want and does it :-)).

Maybe it'd be nice of the mount mode were irrelevant when reading an
existing file, but just controlled what happens when you write a file to
the file system.  Maybe the reading operations could track what kind of
line termination is being used on a file, then succeeding write operations
could use the same style (unless overridden by the open() flags)?  That
sounds weird...and probably unworkable...just food for thought.

How do the MS-land programs that understand both line terminations work?
They probably just accept either on input, then do \r\n on output, right?

Oh, Idunno...

Not necessarily.  Various programs do this, including vim and, I think, NTEmacs.

Yes, NTEmacs does, but I was trying to think of the difficulties involved
in doing a filter program.  It'd be nice if the line termination for the
output file could somehow match its input file....so either the filter
program would have to use the right fopen() flags to designate the right
kind of text output file or the fopen() could intuit the right value by
looking at recent open()/read()'s...that's what I meant by
"weird"/"unworkable".

That would be nice, but not necessary for my purposes. I would be
content if all tools that do text would understand all ASCII text file
input. If that was garanteed for all tools than their output format
could be an arbitrary choice (any one of Unix, DOS, Mac).

OTOH given that I do not have source for some of my tools (esp the OS
supplied), I prefer the output in the native format i.e. DOS. Actually,
thinking about it, I'd say that I would even prefer output in DOS format
over preserving the old format.

Nope, vim for example reads files in "textmode" or "notextmode" and
also writes them in the same manner. This is true for the Cygnus
compiled vim and for the VC++ compiled one under Windows.
Otherwise you would destroy all your Unix style line breaks, when
reading and writing a file with it.

Michael,

This is taken out of context.  vim works as you describe however I
was not insinuating that vim worked as "MS-land" programs.  I was 
considering the original poster's definition of "MS-land" programs
as native Win32 programs and not ports of software to this platform
or others.  If anyone else got the impression I meant otherwise, 
please accept my apologies.

Understanding program startup

[DG Ellis]

  I am not new to C programming, however, I am new to writing programs 
that run under a unix shell like bash.  For history, I found that single 
quotes are not respected by applications that use cygwin.dll when the 
program is invoked from outside bash. I chased down the code to the 
winsup/dcrt0.cc source file and was busy modifying it when I decided to 
check on the behavior of "normal" command lines under bash and under NT.
Well, I see where the code should behave certain ways and does when run 
under NT command processor, but does not behave at all the same when 
under bash.  Now here is my question:
  My suspicion is that the routine dll_crt0_1 is not called if the 
program is run under the shell. Is this correct?  I will try to check on 
libc's crt0 to see if this is true (if I can find the source).  It looks 
like there are a lot of important things in the dll_crt0_1 routine that 
should be done in each case. If they don't get done, what happens?
Could this be the ctrl-C crash problem???

Cygwin bash has been modified to handle this crap.

Compare the differences of the output of `cygcheck -s -r -v' from both systems.
 I'm guessing you have mixed text vs binary mounts somewhere.

the two machines, popcorn (I'll guess is the working one) mount with the
flags as 0x0020 while nachos (I'll guess doesn't work) mounts with 0x0022.
I'll venture a guess that you're accessing the scripts from /cygdrive/?/...
right? (because the other mounts are the same for both.

a solution, as Christopher suggested, is to remove the ^M from the files.
the easiest way I know of to do this is to pipe the script through "tr -d '\r'"
so for example:

tr -d '\r' < /cygdrive/c/myscript > /tmp/myscript
mv -f /tmp/myscript /cygdrive/c/myscript

the other would be to mount the location of the script in an explictly
controlled mount point (text mode), or to change the default mount
mode.

Ok, fine.  I apologize.  I have unpacked and printed the user's guide.
I'll read it.  I've already looked through the FAQ and found nothing
very useful.  I'll look through the mail archives later.

In the meantime, can someone verify whether rerunning setup and
setting the "DOS" text file type should resolve my problem?  When I
tried that, it appeared to have no effect.

Ok, after reading the user's guide, I did the following on the new
system:

   mount -t d: /d

After this, the output of "mount" is the following:

    Device              Directory           Type         Flags
    d:\cygwin\bin       /usr/bin            system       binmode
    d:\cygwin\lib       /usr/lib            system       binmode
    d:\cygwin           /                   system       binmode
    d:                  /d                  user         textmode

I now find that my original .bash* files work fine, even with ^Ms.

Is this the correct solution for this?  All of the files I create will
be stored on the D: partition, but I guess any files that I read from
directories which map to the three "binmode" mounts will be
interpreted differently.  I don't know how much of an issue that is.

The mount table from the original installation just has the first
three, with the only difference being the "Type" is "user" instead of
"system".  From my reading of the UG, that shouldn't matter.

I guess this means that the default mode for unmapped directories is
"text" on my original installation, and "binary" for the second
installation.  Since directories like "d:/dmk" (my home directory) are
not covered by the original mount table, I would get the default.

So, when I install it again, if I select the "DOS" text file type, I
won't have to add this mount to get files on the "D:/" drive to use
DOS text file mode, correct?

What exactly in the "cygcheck" output (or any other place, for that
matter) tells me what the default text file type is?

If you had selected "DOS" originally in setup, all these mounts would have
been set to text.  If that's what you wanted, set them that way now and 
you don't need your added entry.  Otherwise, mount all the other drives you
want to act "DOS" drives with the "text" setting.

If you want your settings to affect only you, that's correct.

You should be able to reset your default mode for unmapped drives using
the --change-cygdrive-prefix setting for mount but specify the "-t" flag
too.  I haven't tried this myself so I don't know if it actually works.

Right.

Nothing.  cygcheck doesn't output that yet.

That's not true.  The output of the registry data can tell you.  0x00000020 is
text mode 0x00000022 is binary mode.

Sorry for needing to rehash this, but could someone tell me EXACTLY
what I need to execute to permanently change the default text file
type to DOS?  I've tried numerous variations of what's described here,
and I can't get it to work on a third installation of this (where the
user neglected to select "DOS" on the initial install).

I've tried the following:

mount -ts --change-cygdrive-prefix /cygdrive
mount -ts --change-cygdrive-prefix /d
mount -t --change-cygdrive-prefix /d

These all just echo the usage message.

After the following:

      mount -t d: /d

I get "mount: warning - /d does not exist".  Doing "mount" after this
shows a new mount entry in textmode, but running "ksh" still gets the
usual error.

AFAICT, mount doesn't accept combined flag options, at least for 
--change-cygdrive-prefix.  Use -t -s.  Also its best to make sure that
you invoke the --change-cygdrive-prefix option without the -s flag, since
you may have set the option for your personal login to something other 
than text in your attempts.  Do the following:

mount -t -s --change-cygdrive-prefix /cygdrive
mount -t --change-cygdrive-prefix /cygdrive

That should do it.  BTW, I don't recommend using a path like "/d" for your
cygdrive path.  Since many people tend to mount their D: drive to /d, this
may become confusing for you.  Whatever suits you is fine, providing you 
understand what you're doing.

As you said, you got the warning.  Mount really wants the POSIX path you 
mount to exist, but it doesn't force it to.  Type "mkdir /d" before the 
mount to remove this warning.

And the other would be to rerun setup and choose the DOS radio button.  Just
rerun setup, no need to redownload anything.

As I still have to work with other applications (Emacs, etc.) which
will continue to write files with DOS line endings, removing the ^Ms
is not a practical option, as I'd have to do that constantly.

I understand the option of rerunning setup and setting the DOS radio
button, but I actually already tried that.  After going through a few
dialogs, it said "Nothing to update" (or something like that), and it
seemed like it had no effect.  However, based on my limited
understanding of this, I think this would probably be the best option
(if I can get it to work).

I don't understand the option of setting text mode mount points.  I
have no idea what the ramifications of that would be.

If Emacs is your major concern, stick the following into your .emacs:

(setq-default buffer-file-coding-system 'undecided-unix)

New files will then be unix-style. Works great here.

Emacs is a major concern, but not my only one.  I don't think it's
practical to try to fix every Windows program to produce Unix line
endings.  I have to focus on getting Cygwin to work with DOS line
endings.

My original installation works fine.  When I ran the second
installation, I think I probably left the "Unix" flag on.  Is it
conceivable that I'll have to uninstall completely so I can reinstall
with the "DOS" flag set?  Rerunning it and setting that flag had no
effect.

David, you should find the background to answer your question in the 
Cygwin User's Guide in the sections discussing mounts and the binary/text
issue.  Setting the "DOS" flag in the installation only indicates whether
mount uses the "-b" (binary) flag or not by default.  This applies to all
mounts setup makes as well as the /cgydrive notation.  There's no other
"magic" going on here.

But that Idiot CVS pulls the ^M back from he CVS server if you

I would appreciate if bash could tolerate ^M in the end of lines.

I don't use CVS here. Is there a specific reason why do you run it in
DOS under NT Emacs?  Bash and ash run just fine as interactive and
non-interactive shells in NT Emacs.

I run both: DOS and BASH shells and sometimes I forgot.

And pcl-cvs.el, runs Emacs call-process, which I think is native 98
kernel, and CVS yanks the ^M to the perfect unix-files that I store in
Linux end.

I hate it :-) I want always plain \n, no matter what platform 
I use CVS on.

I have to push the CVS developers more to really understand that 
"automatic" and non-user-controllable end-of-line conversions
are bad.

Maybe they hear if I request it long enough, or find the time
to offer them a patch...time to go clone myself to get more
job done.

QT

[chris]

Hi;

Just a quick query - has anyone had any luck compiling QT 1.x with
CygWin? I'm assured it's possible (I'm trying to build 1.45, I think) but
the moc meta-object parser thing keeps breaking it - bison won't parse the
.y file at all, and byacc seems to generate broken code.

The source itself claims it won't compile with gnu bison, but I know
someone who claims to have got it to compile...

Anybody got any ideas?
Chris

I just compiled

 o qt-x11-2.2.4 - http://www.trolltech.com/

I copied

 /usr/local/qt/configs/linux-g++-static to /usr/local/qt/configs/cygwin-g++-static

and added platform support in /usr/local/qt/configure

     CYGWIN_NT-4.0:*)
	PLATFORM=cygwin-g++
	;;

In /usr/local/qt/src/kernel/qapplication_x11.cpp I added

#if defined(_OS_CYGWIN_)
#  include <sys/socket.h> // for FIONREAD on Cygwin
#endif

In /usr/local/qt/src/network
the file qdns.cpp needed the header files from bind to compile.

And for the examples (ftpclient, httpd, mail and networkprotocol) I added
 -L/usr/local/bind/lib -lbind 
in the appropriate Makefile.

All examples and tutorials are working

I've been waiting to see this for awhile. :) Question, did you install bind 
or just the headers? I am assuming you did install it, so what version did 
you use and how did you get it to build? So far, I am not finding anything 
on the website. Thanks.

RE: QT - request for bind cygwin patch file

[Kevin Wright]

Hello,

I've been trying unsuccessfully to get Stephen Biggs bind patch since 
I saw this email. Since the files are in the incoming directory they
are forbidden to download. I sent Michael Hirmke a request to move
them to a porters directory but he's waiting for a proper readme file
from Stephen.

I've tried getting the patch directly from Stephen but apparently 
he's swamped at the moment. 

Is there anyone else out there you can forward it to the list. I just
want the patch file not the binaries.  

Thanks,

--Kevin

That bug has been discussed here.

bash does its own command line processing, so doing it in dcrt0
for programs run under bash would just mess things up.

No, not at all.  Note the code in dll_crt0_1:

  if (! u->self->cygwin_parent_p)
    globify (&argc, &argv);

That does wildcard expansion if cygwin_parent_p isn't set.
cygwin_parent_p is set in pinfo_init (which is called a bit earlier
in dll_crt0_1) if the PID environment variable is set and matches
the corresponding process table (pinfo) entry.  That will be the
case if this process was execed by a cygwin process, such as bash.
There are of course other messy and confusing details.

cygwin_crt0 in winsup/libccrt0.c, which is linked into the application
code, calls the dll_crt0 in dcrt0.cc in cygwin.dll.

Nothing useful, since dll_crt0_1 calls main, among its other important
functions.

Nope, sorry.

Although this may be secondary to your concerns, or in fact may be 
totally off topic, I notice that libglu32.a and libopengl32.a are 
both included with the beta 17.1 distribution. I'm not sure about 
the header files, but if you can get your code to compile you should 
be able to link it with ld. Of course this doesn't help if what you 
really want is DirectX or some other thing that comes with .lib 
files you can't convert to .a files.
     
     Actually, that is interesting.  From the distribution I downloaded, 
     libglu32.a and libopengl32.a are not available.  However, I am 
     interested in the general problem of linking with MS lib's (ie, 
     glaux.lib).
     
     I suspect that I could use dlltool to generate an import library for 
     glu32.dll and opengl32.dll.  I'll give it a try.

This suggests to me that you need to include crt0.o in your link line 
explicitly, since that's where _WinMainCRTStartup should be resolved. 
Well, actually in the Cygnus sources it's not, but you could just add 
a _WinMainCRTStartup entry point which calls the _mainCRTStartup 
entry point and it should work OK I think.
     
     Yes, I thought of that too.
     
     //f/pgming/OpenGL/simple$ make
     link simple.o crt0.o libuser32.a glu32.lib opengl32.lib libgdi32.a 
     /subsystem:windows /machine:i386

     simple.exe : fatal error LNK1120: 2 unresolved externals
     make: *** [simple.exe] Error 25
     //f/pgming/OpenGL/simple$
     
     
     So, I can trade WinMainCRTStartup() for cygwin_crt0().  Not much 
     progress.  Though, this has to be defined somewhere!  Which library?  
     Unfortunately, I don't know how to list the functions in a library. 
     (how embarrassing) :+(
     
     BTW: instead of defining WinMainCRTStartup(), it's easier to use the 
     link option /ENTRY:mainCRTStartup.


Sorry for the rampant uncertainty,

     Hay, at least it's better than calling me crazy for not using MSVC.  
     Actually, I am using VC++ 5.0 but I'd rather not.

Linking with .LIB files

[David W Palmer]

     
     Yes, I know this has been covered before.  Unfortunately, I can't find 
     the necessary information to get this to work other than to use 
     link.exe and it might work.
     
     So, I have a simple program which uses OpenGL and I link with the 
     following:
     
     link simple.o libuser32.a glu32.lib opengl32.lib libgdi32.a 
     /subsystem:windows /machine:i386
     
     And of course, I get the following:

Just what sort of thing is simple.o?  If it is a POSIXish
thing that has a main() and uses the POSIXish stuff provided by
cygwin.dll then you need crt0.o and libcygwin.a and possibly others, and
tell the linker that the entry point is _mainCRTStartup.  If it's a
win32ish thing then you should be providing your own _WinMainCRTStartup
or tell the linker just what *is* your entry point.

You still haven't told the linker what the entry point is or
provided a _WinMainCRTStartup; read Colin's comments above again.

No, now you are missing both.

libcygwin.a.  cygwin_crt0 calls dll_crt0 in cygwin.dll.

nm for *.a

But you didn't.  You need to tell the linker your entry point or provide
a _WinMainCRTStartup.

Re[2]: Linking with .LIB files

[David W Palmer]

Text item: 


     Okay, the 'ol linking problem.
     
     I tried declaring the following in simple.c:

void (*__CTOR_LIST__)(void) = 0;
void (*__DTOR_LIST__)(void) = 0;
char _data_start__, _data_end__, _bss_start__, _bss_end__;

     It compiled!  But would exit immediately when ran.
     
     "gdb simple.exe" faulted, dumped the stack, and exited before running the 
     program.  (ouch!)
     
     So, I tried the next suggestion: since the sample doesn't use any cygwin 
     functions, use MS libraries instead.  This worked to the extent of linking. 
      Simple.exe again exits immediately after running.
     
     "gdb simple.exe" shows that it runs, but gets a 0 from CreateWindow().  So, 
     I compared this behavior against what cl.exe does.  Here's as far as I've 
     gotten:
     
     case 1: compile using
         gcc -c simple.c -o simple.o -DWIN32 -D_DEBUG -D_WINDOWS
     
     case 2: compile using
         cl   /D "WIN32" /D "_DEBUG" /D "_WINDOWS"    /c simple.c
         mv simple.obj simple.o

     In both cases, link using:
        link /NOD simple.o libc.lib kernel32.lib user32.lib gdi32.lib
     winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib
     uuid.lib odbc32.lib odbccp32.lib opengl32.lib glu32.lib /nologo 
     /subsystem:windows /debug /machine:I386 /out:"Simple.exe"
     
     I removed the "\"s for formatting reasons in this e-mail.  And yes, I know 
     I don't need the majority of those .lib's - I just grabbed it from a 
     working simple.mak generated by VC 5.0.
     
     Both methods generate a simple.exe that will run.  However, case 2 
     successfully creates a window and the program runs fine.  Case 1 gets a 0 
     return code from CreateWindow().  (sigh)
     
     BTW, the GNU-Win32 FAQ at 
       http://www.cygnus.com/misc/gnu-win32/faq.html#SEC57
     
     says:
     -----
     Can I mix objects compiled with msvc++ and gcc?
     
     Yes, this supposedly works. The key seems to be using MS's LINK.EXE to do 
     the linking instead of GNU ld. There may be issues with constructor calls 
     for C++/Obj C.
     -----
     I see no evidence that could possibly support this claim.  Though I have 
     not tried all possible combinations, I'm inclined to believe that gcc and 
     link are incompatible as suggested by Wiljan.  If this is not the case, I'd 
     appreciate seeing a sample that works.  Regardless, the FAQ should be 
     updated.

I believe (but have not verified) that ld generates these.
So, if link doesn't produce some equivalent that can be
massaged/converted
into what cygwin.dll is expecting (libccrt0.o just stashes them for use
later
by cygwin.dll) you may be out of luck.  However, the _start_ and _end_
symbols
are only used by fork, which you probably aren't using, and the LISTs
are C++
ConstrucTOR and DesstrucTOR lists, which you probably also don't need. 
So, try
just defining all these to null in the link command line or script file,
or
define them in simple.c, and see how that goes.  You need to strip one
'_' if
you define them in a .c file on a x86 box (but not on a PowerPC box).
i.e., add

void (*__CTOR_LIST__)(void) = 0;
void (*__CTOR_LIST__)(void) = 0;
char _data_start__, _data_end__, _bss_start__, _bss_end__;

to simple.c and fire 'er up.

     Simple.c is a very simple windows program (with a WinMain) that calls

     The GNU-Win32 I'm using I pulled from

     Apparently this is b17, not b17.1.  Sounds like getting the patches to 
     b17.1 should resolve the issue of using OpenGL.  Though I'm still 
     interested in getting this to work.  (call me stubborn if you like)
     
     So, any ideas about why I'm missing these symbols and what can I do about 
     it?
     
     Thanks, for the help guy's!  I do appreciate it!

Re[2]: globbing feature in 17.1 when not under bash issue (b

[DG Ellis]

Text item: 

I agree. I have just been looking at the code in .....
   cdksrc/winsup/dcrt0.cc  where the globing takes place.

There is code to "de-quote" and double quoted string in all cases when
argc/argv is being created and code to glob if not invoked under another 
cygwin32 app. The problem is, these are done in this order and in 2 
different routines.  My take at it is that the shell (bash) removes the 
outer set of quotes 'barfl more' or "bore me to" (assume normal unix 
behavior right?) and then calls the app with these sanitized strings. 
Thus the normal take would be to do no quote handling at all in the 
under-bash condition. However, if not, then should do whatever and as 
much as you want that the shell would have done had it been there:
  1: quote removal
  2: environ string expansion
  3: globing
  4: more?
I am hard pressed to find an elegant (read simple) way to convey that 
the argv entry was quoted after leaving the "build_argv" routine and as 
it goes into the "globify".  I vote for sending in the flag
 u->self->cygwin_parent_p  (set only if spawned from another cygwin app 
I assume) and combining the build_argv and globify into one routine.

I do it. You doit. Other ideas?

Not with single quotes it doesn't.

Huh? cmd.exe does not do globbing.  Under DOS/Windows, globbing 
is up to the individual commands to do.

David Ellis is right that cygwin doesn't handle quotes properly, 
but he's wrong about the argument being expanded in single quotes.

Under cmd.exe:

 ls *.doc    -> a.doc b.doc c.doc

 ls "*.doc"  -> a.doc b.doc c.doc
    BOGUS cygwin expands

 ls '*.doc'  -> ls '*.doc': no such file or directory
    BOGUS cygwin fails to strip single quotes

Re[2]: Understanding program startup

[DG Ellis]

Text item: 

Hello,
 I went and looked at libccrt0.cc and was able to figure out exactly what you 
where saying. However I still did not know how bash could pass the command line 
to an app when it was in the form of a string (and not an argv vector). I then 
decided to look at spawn.cc and found the code that I was hoping for. In that 
code, an argv is passed and is then processed into a "cooked" command line. This
cooking includes space detecting and quoting. It also doubles up on d-quotes 
(which are undone in dcrt0 build_argv). So I see where the process is done and 
complete. Now that I see the role of the code in dcrt0 for normal command lines,
I can now figure the "correct" path to take to help in the s-quote being ignored
etc behavior when the program is invoked outside a cygwin process.  Here is my 
proposal:

Move the "globify" call to before the compute_argc/build_argv sequence and 
operate on the original command line. Also within the confines of this "run only
if not under cygwin32" condition, pre-process the command line similar to the 
work done in spawn.cc that will respect d-quotes and s-quotes and wrap 
parameters with quoted spaces in d-quotes as spawn.cc does. This would not be a 
perfect process because this code would be working on the command string instead
of the original argv vector as in spawn. This code could also determine if the 
globbing characters are within quotes or not and not glob those. This "cooked" 
command line then could be passed on to compute_argc/build_argv as normal.  This
should bring the behavior in line (at least closer) with the operation under the
shell.

 Now the hard part, I probably won't be able to do this in the short term. I 
have worked around my original problem by just using d-quotes where I was using 
s-quotes.

   Thanks for the encouragement to look further into the process taken by a 
command in bash.

    Dave

That bug has been discussed here.

bash does its own command line processing, so doing it in dcrt0
for programs run under bash would just mess things up.

No, not at all.  Note the code in dll_crt0_1:

  if (! u->self->cygwin_parent_p)
    globify (&argc, &argv);

That does wildcard expansion if cygwin_parent_p isn't set.
cygwin_parent_p is set in pinfo_init (which is called a bit earlier
in dll_crt0_1) if the PID environment variable is set and matches
the corresponding process table (pinfo) entry.  That will be the
case if this process was execed by a cygwin process, such as bash.
There are of course other messy and confusing details.

cygwin_crt0 in winsup/libccrt0.c, which is linked into the application
code, calls the dll_crt0 in dcrt0.cc in cygwin.dll.

Nothing useful, since dll_crt0_1 calls main, among its other important
functions.

Nope, sorry.

Re: Windows API calls that don't work? (Was RE: Stupid stupi

     Colin, 
      
     I just tried Smith's code under WinNT 4.0 using GNU-Win32 with no 
     source modifications.
     
     It compiled and ran properly with commented out code.  However, it 
     failed as he described with the code included.
     
     I also compiled it under VC++ 5.0 (though I had to change STDCALL to 
     WINAPI).  It worked fine in all cases.  The modified sample program 
     still wouldn't work when compiled with GCC.
     
> Are you using a completely vanilla version of GNU-Win32 or have you 
made changes to things (like the startup code for example)? Could you 
send me a copy of your silently failing binary?
     
     Out of the box GNU-Win32.  I'll send you a mime encoded version of my 
     gcc generated exe.  It's a little large to send to the mailing list.
     
> PS. Any confirmations on that statement about NT from other readers?
    Does stripping an executable make it work? Do you *have* to strip 
    on NT? Is there a difference between the -s link option and using 
    strip after linking?

     I tried the following commands:
        strip test.exe
     and 
        strip test.exe -o tests.exe
     
     Neither cases made any difference.
     
     Running the program from BASH under NTEmacs produces the 
     following stack dump:

Tried that.  It made a very small lib (1514 bytes).  I have read 
about needing a .def and/or export file.  But nothing about how to 
make them, either :).

Re[2]: env command does not work correctly.

[DG Ellis]

Text item: 


Simple minor note that the $foo in the command below is interpreted by the
original command line interpreter before the actual statement is executed.
This is why this example will not work. The example given in the post by
Fabio is correct in its use.
  You could try:

  foo=hi eval echo '$foo'

This would cause $foo to be protected first time arround, then let
eval evaluate the command after the assignment and do the echo.

     env is a command typically used in csh-like shells. With bash, you can
     just say:

     ONE=one TWO=two echo_1_2

     This also does not work with cygwin32 17.1.

     The simple statement: foo=hello echo $foo
     doesn't work.

     Also I am not real familiar with unix so I don't know if this is a bug
     or not:  Only uppercase environment variables can be exported.

Under Linux, env works fine with both tcsh and bash.  I haven't tried
env with cygwin---I wasn't even aware of its inclusion---and right now
I have no access to my Win95 laptop. But it looks like a bug.
