make -mno-win32 the gcc default?

make -mno-win32 the gcc default?

[Christopher Faylor]

So, what does everyone think about making -mno-win32 the default for Cygwin?

This would mean that WIN32 variables would not be defined by gcc by default.
It would require a -mwin32 switch for these to be activated.

Earnie has been proposing this and I sort of like the idea but dread the
potential hue and cry that could result.

So, is the hue and cry from the lack of WIN32 counterbalanced by potentially
easier UNIX porting?

Yes.  It fits with the stated goals of Cygwin.  We can counter the outcry 
with a nice FAQ so we at least will not have to repeat ourselves constantly.

I'm in!

I also like the idea, but am terrified of the torrent of "It worked with
gcc-2.95.2 and cygwin beta 1.1 [sic]" complaints.  Also I'm not sure
that all of "my" packages are _WIN32 clean.  (For the most part, if they
compiled -- I was happy.  I didn't look too closely beyond that.  I know
that zlib and libpng are WIN32 clean 'cause I tested them with
-mno-win32.  Dunno *for sure* about the rest).

You mean like this?

    Why am I getting errors from "windef.h"?
    Why am I getting errors saying simple things like "HANDLE" are undefined?
    Why can't I compile my Windows program with Cygwin 1.1.8?  It worked fine
    with B19!

    Please send email to lhall@rfk.com and he'll explain everything.

My sentiments exactly.

We could always make a release, see who complained, and then change it back if
it seemed like a bad idea.

Yes, something like that.;-)

Seriously though, I'm betting on the fact that its easier to answer questions
about why Win32 programs don't compile by default than it is to explain why
Cygwin won't build and run GNU/UNIX packages.  Of course, as Chuck Wilson
points out, there will be those packages which are ported to both UNIX and
Windows that seem to work right now because they make use of some Win32 
stuff that won't be allowed with this change.  While I expect most of these
will still build, they might break when running.  Questions about these 
will potentially be prolific at the beginning but at least the solution is
cleanly stated (port it properly) unless the functionality in Cygwin is 
missing.  There's some grey area but I expect the result for any strict 
Win32 program will be that it won't compile which is handled by 1 simple
FAQ (i.e. add the -mwin32 flag for Windows programs).  The result for any
UNIX port will be either the package won't compile or program errors/bugs 
(due to bad porting or lack of Cygwin support).  Another general FAQ can
handle that too.  While the initial volume of all these complaints may be 
high, it will tend to force the packages and Cywgin to get better.  Add to 
this the fact that we won't have people wondering why their favorite GNU 
package uses Win32 block of code under Cygwin instead of the UNIX/POSIX 
code and I think this will be a plus (or at least easier to explain!;-))  

Thus ends my diatribe on how things work in a perfect world.;-)

Re: make -mno-win32 the gcc default?

[Christopher Faylor]

I didn't see this in the Cygwin mailing list but the CYGWIN environment
variable controls the behavior of the Cygwin DLL.  GCC is not the Cygwin
DLL.

This has nothing to do with "cygwin" or "make".

So, Charles' suggestion is correct.

Yes, I like this.  This should be the answer to the FAQ question!:-)

Would it be possible (or desirable) to make it selectable
by the user.  Some people might prefer to always have "-mno-win32"
as the default behavior and others might want "-mwin32" and
I'm sure that there are others that might want to switch back
and forth between the two.

If it is selectable then, it will be like it is now,

set: export CC='gcc -mno-cygwin'
or:  export CC='gcc -mno-win32'

and so on.

What will be the difference then, to like it is now?

Is there no default setting in gcc?
Does it switch between both settings, randomly?

BTW, as i tried to compile perl with gcc -mno-win32, some days ago,
as this was first mentioned, it didn't build OOTB as usual...

I suggest, there will be a lot of applications to be rebuild.

Hm, I would've sworn that Earnie Boyd had said sometime in the last week 
or so that Perl did indeed build with -mno-win32.  Perhaps I'm mistaken.

I think its important to point out that this change would not necessitate
any applications being rebuilt.  It's worthwhile to make sure that they 
do build and still work as a result but the change itself does not 
invalidate existing executables.  Also, for anyone that wants to make 
sure that their application would build OK with this change (assuming it
should), its easy to do now just as you did above for Perl.

I guess that I was meaning something that might
be MORE visible to new users.  The "export CC= ..."
approach seems like something that a newbie might 
not notice.

Yes. I said that.  My default mode is without WIN32 defines and has been for
a couple of years.  In that time I've built varying versions of perl and
have not had problems.

IMO, having this default would catch fewer newbies by surprise than the
well adjusted Cygwin user.

I suppose to ease some of the pain we could create a windows.h file for
/usr/include that does appropriate comparisons and issues an #error if  it gets
included without _WIN32 being defined #else include the next windows.h file?

Cheers,
Earnie.

And, at least this one will be announced, unlike a few changes that I can
think of but won't mention.

perhaps  we  should put

No, you're right, he said so.

Well, maybe it works with some modifications,
also i should mention, i tried the unstable devel-sources.

I'm sure, some configure-scripts override the environment-settings.
A lot of sources come with ready-to-use Makefile which is to edit by hand.

Yeah, you're probably right.  But lots of times I'll do this:

CFLAGS="...." LDFLAGS="....." ./configure 

and if it were me, I *know* I'd forget to add "-mno-win32" every time. 
However, I hardly ever mess with "CC" or "CXX". Therefore, those
variables are "safe" -- they won't be accidentally overridden.  But
that's just my tendencies.  I'm sure other people have their own.

devel-sources?  Yes, I expect that's the reason for the problems you're 
seeing.

Now i tried also with perl-5.6.1-TRIAL-1, the patched source, it does not 
compile OOTB:-\

Ask Eric why, please.

No, he's wrong, IMO.  CC, CXX are the correct variables to set.  The
reason is that CFLAGS and CXXFLAGS should be used for optimization and
flags that are architecture independent while the architecture dependent
flags should be passed with the CC, CXX variables.  This allows the
configure script to use the architecture dependent flags in it's checks
for what's available.  Otherwise, you might misconfigure the package.

Cheers,
Earnie.

Yes.  I think that Earnie is right here.
