Problems

Problems

[Doug Whiting]

I just installed Cygwin from the Internet, and things are very close to
working fine. I have run quite a few things successfully, but there are
three annoying problems, listed below, that I'm hoping have a simple
solution. I looked in your email threads and couldn't find a solution that
works for me.  FYI, I'm running Win2K Professional on a Toshiba Tecra 8200,
with 20GB disk (8GB free) and 256M RAM. 

1) The exe files produced by gcc (e.g., even "hello world") are not
executable. I added set CYGWIN=ntsec in the
startup batch file, but that made no difference. I'm an administrator on the
system, so I have all
rights.  When I use the Windows Explorer to set the security of the file
a.exe to executable, 
it runs fine, but that's hard to put in a makefile :-( 

2) In trying to fix the above, I found that chmod doesn't work. 
I get the following error message, no matter what switches I try to give it
(and I've tried a lot):
	$ chmod a+x a.exe
	chmod: changing permissions of `a.exe': Invalid argument
Perhaps these two problems are related, but together they make life quite
difficult. It seems
almost like chmod is not complaining about the syntax, not the inability to
set the attribute,
but of course that may be reading too much into the error message.

3) An apparently unrelated problem with Emacs: when I type C-x C-c to kill
(exit) Emacs, the
computer just beeps at me and does nothing. I have to do "M-x Kill Emacs",
which is a real pain. 

Any ideas on these problems? It's probably just some simple configuration
stuff, but I've spent a few hours fiddling with it to no avail.

Normally people are assumed to make a reasonable effort in searching the
archives, and it's understood that it's hard to phrase a query correctly.
However, in this case, searching for "gcc exe not executable" (in the
October archives) produced multiple relevant messages.  I refer you to
those.
FYI, ntsec is on by default in Cygwin-1.3.13+.

Same problem as above.  FWIW, you could have searched for "chmod doesn't
work".

Again, the proper search query is "emacs Ctrl-C"...  As there are quite a
few unrelated messages in the results, I'll answer this one: you should
look into the 'tty' setting in your CYGWIN variable.

Archive search and Google are your friends. :-D

A friendly advice: a subject like "Problems" is completely useless; it'll
get ignored by everybody who (like me) just browse the subject lines for
interesting postings. 

Supplying a sensible subject line will significantly increase the chance
that your posting is actually read by people who can help you. Otherwise
you'll just get a "because we're mean" response from CGF. ;-)

Nah, I reserve that response for a particular type of query.

Doug,

If you read all the relevant messages, you'll see that your /etc/passwd is
probably not up to date.  Try re-generating it with 'mkpasswd >
/etc/passwd' (having made a backup first, of course, and with all the
appropriate flags for a domain user).

There are some problems with the 'tty' setting (I, in particular, don't
use it), but if it works for you, all the better.

RE: Problems

[Doug Whiting]

Thanks. No offense taken, though I actually had searched through the
gcc/chmod stuff fairly carefully, and nothing suggested there had worked. I
finally just turned OFF the ntsec stuff (CYGWIN=nontsec), and that fixed the
problem!  It appears that there's a bug of some sort with either the new
default setting or the ntsec functionality itself. Anyway, now chmod and gcc
work fine, but I'm not sure how I should have guessed to go against the
grain by turning off the feature that is claimed by all the emails to fix
the bug :-(

The emacs C-X C-c worked after adding the tty element, but I had to take out
the space before and after '=' in the batch file.  That is
   set CYGWIN = tty
did not work, but
   set CYGWIN=tty
did work!  Anyway, thanks for that pointer, as it was not at all obvious
from the (too many) matches to my search queries. Kinda seems like tty
should be the default, but in any case I'm up and rolling now.

Thanks again.

Hi folks,

	Lot of them.  Astrophysics was a major of mine in early college days 
when a formal Computer Science curriculum had yet to be started at my 
college.  Ended up majoring in Astrophysics while minoring in a 
personal focus on Computer Science.

	At any rate, we need to establish what your assumptions currently are.

	Here are the basic Cygwin installation assumptions:

	You were wanting some sort of development environment to work in.
	You used setup.exe from the cygwin website to install Cygwin.
	You allowed install to add the cygwin icon to your desktop.
	You launched Cygwin using the desktop icon installed by the Cygwin
	setup utility.

	Now, which of the above assumptions are true?  I can deduce that you 
installed Cygwin because you thought it would meet your basic needs 
regardless of development environment.

	DOS has little to do with Cygwin development.  It only acts as an 
elemental substrata of sorts which is specifically being used to 
support the use of a "Unix like shell" within, amongst other things, a 
Windows based operating system (platform).

	Metaphorically, Cygwin might be considered a nebula of sorts (and yes, 
it can be quite nebulous sometimes ;-)).  The DOS shell is just one 
element in the metaphoric nebulas' gaseous soup.

	Now some questions:

		Are you speaking of Windows 98 or Windows NT4 when you talk about the 
behaviour you noted above?  (This is how I establish the basis of a 
theory where Cygwin is concerned).

	From here the number of causes multiplies, so we need to know which OS 
you are actually using.

	Thanks,

		Paul G.

Open the properties of the CygWin icon you are clicking on to launch
CygWin. Clear the "Close on Exit" box. Now the DOS window will hang around
instead of disappearing in a flash and you will be able to read whatever
error message is really being written there. Odds are, that message will be
mentioned in the FAQ or in the mailing list archives.

Boy is this a FAQ!  Perhaps many people don't equate this kind of 
behavior with the FAQ entry:

What if setup fails?
http://www.cygwin.com/faq/faq_2.html#SEC15

However, this is exactly what happened.  Setup failed to install properly
on your system, either because you didn't install all packages as you're
supposed to or because of some issue not necessarily in your control.  See 
this FAQ entry for suggestions in the latter case.  Make sure you try 
*all* the options mentioned in the FAQ.  If one doesn't work, try the 
others.  If you're still having a problem, you can contact the list again
with the details the FAQ suggests.

Then why are you even downloading this package?  Stick with Microsoft pointy
clicky tools.  This is a UNIX emulation environment.

If you don't have any ideas what that means then you don't need cygwin.

I have tried to install cygwin on both an NT and Win98 machine and while it
seems to install OK, when I try to open all I get is a fraction of a second
appearance of a DOS window that disappears. I cannot get beyond this

PROBLEMs

[Daniel Santos]

Hello,

	My name is Daniel Santos, I download a copy of win-gnu32 and i have
some problem
that i can't find answers in FAQ. I get a source code that I can compile
it in Linix and have no problem, and when a try to compile it on
wingnu32 I receive 3 erros message.

	A part of source is here:

void    signal_setup(void)
{
   struct itimerval itime;           			<======     35
   struct timeval interval;

   signal(SIGUSR1, reread_wizlists);
   signal(SIGUSR2, unrestrict_game);

   /* just to be on the safe side: */

   signal(SIGHUP, hupsig);
   signal(SIGPIPE, SIG_IGN);
   signal(SIGINT, hupsig);
   signal(SIGALRM, logsig);
   signal(SIGTERM, hupsig);
/*
   signal(SIGSEGV, badcrash);
   signal(SIGBUS, badcrash);
*/
   /* set up the deadlock-protection */

   interval.tv_sec = 900;    /* 15 minutes */
   interval.tv_usec = 0;
   itime.it_interval = interval;
   itime.it_value = interval;*/

   setitimer(ITIMER_VIRTUAL, &itime, 0);            <======  58
   signal(SIGVTALRM, checkpointing);	           <======  59
}

Messages Erros:

signals.c: In function `signal_setup':
signals.c:35: storage size of `itime' isn't known
signals.c:58: `ITIMER_VIRTUAL' undeclared (first use this function)
signals.c:58: (Each undeclared identifier is reported only once
signals.c:58: for each function it appears in.)
signals.c:59: `SIGVTALRM' undeclared (first use this function)
signals.c:59: warning: passing arg 2 of `signal' from incompatible

	After that I coment this part of code and compile  in link step a
receive one more fatal 
error message:

	comm.o(.text+0x3ce):comm.c: undefined reference to `srandom'
