[Mingw-users] Compiling with gtk for win32

[Leo P. <le...@en...>]

Hello,

I am just trying to compile a test program:
#include <gtk/gtk.h>

int main() {
return 0; }


my gtk is in /usr/win32, so I compile with the command-line

/mingw/bin/mingw32-gcc -I/usr/win32/include/gtk-2.0 -c test.c

I continue to get an error that says 'test.c:1:21: gtk/gtk.h: No such 
file or directory'

Does anyone know why? BTW, this only happens with the mingw compiler. I 
do not get compile-time errors like this with regular gcc compiler for 
cygwin.

Cygwin's shell does not translate the posix path 
/usr/win32/include/gtk-2.0 to its win32 equivalent.  I've overcome this 
issue with MSYS, see http://www.mingw.org/msys.shtml for more 
information.  Look in cygwin list archives for information how to use 
cygwin to do this.

When you say /usr/win32, do you mean that you have on your current
drive a top-level folder called \usr? Or is that a Cygwin path,
corresponding to some completely different Windows path?

If /usr/win32 is a Cygwin path, the mingw gcc doesn't see it.

Besides, you will also need the (equivalent of) -I
/usr/win32/lib/glib-2.0/include to get GLib's machine-dependent
glibconfig.h. And maybe the path to the atk and Pango headers. It's
easiest to use pkg-config, and say:

/mingw/bin/mingw32-gcc `pkg-config --cflags gtk+-2.0` -c test.c

(When you get to the point that you try to run a program you have
compiled, you will notice that GTK tells you also to use the
-mms-bitfields switch.)
