[directfb-dev] DirectFb/Fbdev Caught Signal 11

[Arun Patole]

Hi All,

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


<directfb-dev@directfb.org>(*) DirectFB/Core: Single Application Core.

Any idea, how it can be resolved??


Thanks in advance,

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;
}
