Many thanks for all the advices. I wanted to say that I compile perflectly my GTK applications
using MinGW, but I am now triying to do the same using MS-VC++.
None worked.
I changed my target to "Win32 Console Application" and it compiles smootly bu when I try to run it it simply open a console
(i do no know why this does not surprise me...:)...) and produces an error.
If I define the WinMain function as you recommended, the compiler still produces an error at link time:
I am doing something really stupid probably, but I could not find any clue nor any tutorial and/or documentation
on compiling GTk Applications using MS-VC++
My code is attached to this msg.
Any idea will be welcome.
Thanks
Oscar

Or even:
#include <stdlib.h>
...
return main (__argc, __argv);
__argc and __argv are set up by the C runtime at startup based on the
command line used to start the process even for WinMain programs.
