Hi,
I had MXE build successfully on CentOS 7 which I used for a long time
without any problem with Gtk2.
Recently, I try Gtk3 use the following commands:
x86_64-w64-mingw32.static-gcc -mms-bitfields hello.c \
`x86_64-w64-mingw32.static-pkg-config --cflags --libs gtk+-3.0` -o hello.exe
or
i686-w64-mingw32.static-gcc -mms-bitfields hello.c \
`i686-w64-mingw32.static-pkg-config --cflags --libs gtk+-3.0` -o hello.exe
where hello.c is a simple app. which has only one button (It run well when compile with Gtk2).
The hello.exe can run by WINE. But when I copy it to 64bits Win7, it crash !!!
Anyone has similar problem ?
NOTE: it can't run on WinXP neither, but I believe that's because Gtk3 no longer support WinXP.
The following is hello.c:
#if defined(_WIN32) || defined(_WIN64) || defined(_MSC_VER)
# include <windows.h>
#else
# include <unistd.h>
#endif
#include <gtk/gtk.h>
int
main(int argc, char *argv[])
{
GtkWidget *win, *button;
gtk_init(&argc, &argv);
win = gtk_window_new(GTK_WINDOW_TOPLEVEL);
button = gtk_button_new_with_label("Hello");
gtk_container_add(GTK_CONTAINER(win), button);
gtk_widget_show_all(win);
gtk_main();
exit(0);
}
I decide to use gdb.exe to take a look ....
d:\tmp>gdb.exe hello.exe
GNU gdb (GDB) 7.12.1
...
(gdb) run
Starting program: d:\tmp\hello.exe
[New Thread 6044.0x10e8]

...
The problem comes from gdk_win32_display_get_monitor() !!
That give me some cues ...
I realize that I run the hello.exe on Win7 via rdesktop.exe !! So, I go to the
physical monitor and run the hello.exe again ... and it works !!!
Best Regards,
