compile qt free edition on cygwin with -mno-cygwin
Message 1 in thread
Hi,
I've compiled qt with mingw already. I'd like to know if I can compile
qt with cygwin g++ -mno-cygwin?
Thanks,

Is this possible? If not, why make a build system that is so inflexible?

inflexible? LOL, you don't know qmake.
If you want to compile with a different compiler use the proper
variables to tell Qt's configure (like CC, CXX). Also checkout the
options that configure takes.
Also you may need the Qt/X11 version, as Cygwin is *nix on Windows.

I'm not sure exactly what is funny about this.
That is correct, I know nothing about qmake. My first experience with
it, so far, seems to be a failure. I'd like to cross compile the windows
version of qt from cygwin to mingw using the 'gcc -mno-cygwin' command.
If this is possible, I'd be very greatful to know how. If it's not
possible, how could you not consider qmake inflexible?

Yes, I'm familiar with this. Although, simply specifing the CC and CXX
variables doesn't seem to work nicely with ./configure. For some reason,
the cygwin sh may not be on the path.

I don't want to build qt for cygwin. I just want to use cygwin as a
cross compile environment to build windows qt nativly using mingw.
Any suggestions? Thanks for your help so far.
Thanks,

There's something I don't quite understand yet. You want to use cygwin to
build with mingw?
AFAIK, cygwin and mingw are two different things trying to do quite the same
thing (ok ok, I am perhaps much confused here, if so, any explanation would
be much appreciated).
Anyway ¿which is the problem of compiling just with mingw? I'm doing that now,
including OGL widgets and so, and it works perfectly.

I have successfully built windows qt with mingw from the dos shell. This
does work nicely. Just as you can cross compile qt from linux to windows
using a mingw cross compiler, I'd like to cross compile from cygwin to
windows using a mingw cross compiler. The cygwin 'g++ -mno-cygwin'
provides a mingw cross compiler. It's not exactly a cross compiler,
however, when the flag is used, the resulting binary has no dependency
on the cygwin1.dll.
Now, the reason I want to cross compile qt from cygwin to mingw is
complicated. I currently want to use both qt and apr. qt compiles nicely
with mingw nativly. apr compiles nicely with mingw nativly, and with
cygwin cross compile command. So, using mingw/msys is possible, but, I
have to be locally on the machine to build. Cygwin provides ssh,
however, it's not possible, as I understand it, to get from a cygwin ssh
shell into a mingw/msys environment. I've asked this on both the cygwin
and mingw-users lists, and no one can provide a solution. So, my hope
was to compile qt with cygwin cross compiler, so that I can get an
environment working where I can do builds remotely.
I hope this explanation is useful.
Thanks,
Bob Rossi

I didn't mean to offend you. QMake is messy, undocumented and hackish at
times, but certainly not inflexible.

Hmm, maybe I don't get the point, but why don't you use mingw directly?
Qt4 can be compiled with mingw, for Qt3 there exists this "inofficial"
port of the free edition to windows.

Being able to cross-compile is not necessarily a limitation of the build
system, in fact from qmake's point of view there's nothing that prevents
cross compilation. The problem probably is more on the side of the
cross-compiler.

It seems you also have to set some gcc-flags, see the qmake
documentation for the proper variables to do this. I'm not sure how to
set those though, probably by setting them in the .qmake.cache file in
the Qt root dir.

Ah, ok. But I don't really see the point in that. Why do you want to
cross-compile from cygwin, when you have a Windows box already? Just
install the Qt4-mingw edition, or install mingw and compile Qt4.

It's OK. I honestly don't know anything about qmake. It just seems I
can't get accomplished what I need to.

Using mingw directly does work fine for me. Please see my other response
in this thread for the reason I would like not to use the mingw compiler
directly.

Well, that's possible. The whole thing is sort of a big mess. I mean,
the compiler I need is cygwin's compiler, and I need cygwin's compiler
on my path in order to do a build. However, qmake get's mad when I have
cygwin's sh on my path. Also, for some reason, the windows build expects
mingw-make to be on the path. Why can't any make be used?

OK, that's interseting. Thanks. Does anyone have more info on this?

Again, quickly check out my other response if you don't mind.

Make sure you configure using win32-g++ platform (i.e. configure
-platform win32-g++). And yes you have to remove sh from the PATH,
which is the same when you do a native-mingw compilation.
Other than that, I don't know. I didn't try to cross-compile Qt and I
only installed it once on a Windows box.

Sure, it just arrived after I sent the message. Did you think about a
vnc server or a terminal server solution?

Look into the mkspec directories. One of the gcc ones, (I don't use GCC
on windows) will require you to add a CFLAGS and a CPPFLAGS options for
the flag you need
