[Mingw-msys] Seg fault on printf when porting a Gtk app from Linux to Windows with MSYS

[Patrice St-G. <pa...@us...>]

Hi list,

I am trying to port a Gtk/OpenGL app to Windows (geomorph.sourceforge.net).

I first installed the MinGW - Msys current bundle in a WinXP SP3 VM 
(mingw-get-inst-20101030.exe).

Then I installed separately, in the /mingw directory, the GTK win32 
packages (http://www.gtk.org/download-windows.html). I first tried to 
install the GTK bundle in a distinct directory, but I got some library 
conflicts, which ended with seg faults in internationalization functions 
(bindtextdomain).

I was able to compile my app with ./configure and make, after some 
reordering of the libraries in the linking command. Autoconf / automake 
broke the configure script, so I avoided them.

Now when I execute geomorph.exe from the MSYS shell I get a seg fault in 
printf.

A test with "printf("Hello World!\n");" worked perfectly, though.

After searching the Mingw / Msys forums and the web a few evenings, I 
give up!

The linking command is:

gcc -v -g -O2 -o geomorph.exe -Lc:/MinGW/msys/1.0/lib -Lc:/MinGW/lib 
main.o app.o document.o doctype.o thisappinit.o stack.o ../hf/libhf.a 
../fourier/libfourier.a ../utils/libutils.a  -lgdk-win32-2.0 
-lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0 -lgio-2.0 -lgdk_pixbuf-2.0 
-lpangowin32-1.0 -lgdi32 -lpangocairo-1.0 -lpango-1.0 -lcairo 
-lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl -lglu32 
-lopengl32 -luser32 -lkernel32  -lgtkglext-win32-1.0 
-lgdkglext-win32-1.0 -lpng14 -lmsvcrt -lm &> gcc.txt

The backtrace in GDB is:

Starting program: 
C:\MinGW\msys\1.0\home\Patrice_St-Gelais\geomorph-0.61\src\app/geomorph.exe

 From what I have read on the web and in the system headers, the problem 
is probably related to an internationalisation library which redefines 
printf.

Msys provides /mingw/msys/1.0/lib/libintl.dll.a (gettext 0.17?), Mingw 
also (/mingw/lib/libintl.dll.a) but they are not the same size, and Gtk 
provides /mingw/bin/intl.dll (gettext 0.18!).

How can I compile and link an internationalized program with Msys?

Should I have ever tried at first?

Any help to sort that mess is welcome!

Thanks
