Gtk+ on DirectFb (sample example fails with "DirectFb/Fbdev Caught Signal 11")

["Arun Patole" <webkit arunp gmail com>]

Hi All,

Is the latest GTK+ up to date for building with DirectFB? I tried building it but failed with some multiple definition errors. after resolving them, small demo example crashes.

Do i have to apply any patches to use gtk+ successfully on directFB??

I have built gtk+ on directFb 1.2 and tried to test it with sample application but it fails with following error:

(*) DirectFB/Core: Single Application Core. (2008-12-16 09:14)

Any idea, how it can be resolved??  


Thanks in advance,
Arun

I use DirectFB-1.2.6 and here is simple example i tried:

#include <gtk/gtk.h>

int main( int argc, char *argv[])

{
      GtkWidget *window;

        gtk_init(&argc, &argv);

          window = gtk_window_new(GTK_WINDOW_

TOPLEVEL);
            gtk_widget_show(window);

          gtk_main();

            return 0;
}
 

Here is the stack trace for application crash:
