PLS HELP-URGENT...Error in running GTK application on MIPS board using GTK+ over DirectFB

["Sundeep Prakash" <sundeep prakash gmail com>]

Hi, 

   I have cross compiled GTK+2.10.12 and DirectFB 1.0.0 for MIPS  BCM7401 with all the dependancy as below: 

tiff 3.7.4 
libpng 1.2.18 
libjpeg-6b 
glib 2.12.13 
atk 
1.9.1 
freetype 2.3.4 
fontconfig 2.4.2 
cairo 1.2.6 
pango 1.16.4 

and used the configuration parameter as given at 
http://www.directfb.org/wiki/index.php/Projects:GTK_on_DirectFB_for_Embedded_Systems.

I executed a simple GTK program(code snippet below) which loads an image

#include <gtk/gtk.h> 

int main( int   argc, char *argv[] ) 
{ 
        GtkWidget *window; 
        GtkWidget *pMainWidget; 
        GdkPixbuf *image; 
        gboolean ret = 0; 
        gtk_init (&argc, &argv); 
        
        window = gtk_window_new (GTK_WINDOW_TOPLEVEL); 
        
        gtk_container_set_border_width (GTK_CONTAINER (window), 10); 
        
        image  = gdk_pixbuf_new_from_file ("test.gif", NULL); 
    if (!image) 
                return FALSE; 
    pMainWidget = gtk_image_new_from_pixbuf(image); 
        
        gtk_widget_show (pMainWidget); 
        
        gtk_container_add (GTK_CONTAINER (window), pMainWidget); 
    
        gtk_widget_show (window); 
        
        gtk_main (); 

        return 0; 
} 


Initially, execution failed at 

ret=directfb->GetInputDevice(directfb, DIDID_KEYBOARD, &keyboard) ;

in gtk+-2.10.14/gdk/directfb/gdkdisplay-
directfb.c   

I commented out some line related to keyboard because WE ARE NOT USING ANY INPUT DEVICE. 

The commented lines in file gdkdisplay-directfb.c are below: 

//ret=directfb->GetInputDevice(directfb, DIDID_KEYBOARD, &keyboard) 

//_gdk_display->keyboard=keyboard; 

//_gdk_directfb_keyboard_init (); 

//_gdk_input_init (); 


I again cross compiled and executed the same GTK example mentioned above.  
This time the code executed and got stuck in a function. 

I had put some debug messages in GTK library and below is the log of debug messages

It is not able to exit from g_main_loop_run (loop) function which is called from gtk_main() function. 

I am stuck here and not able to proceed further.
