HI,
I am trying to run gtk-directfb applications on xscale pxa255 based arm
board.(compulabs CMX255 SBC).
Following is the libraries which i have successfully cross compiled and
installed following deirectFBwiki's GTK on dierctFB for embedded systems in
the
order given below :
glib-2.12.0
atk-1.9.1
freetype-2.3.5
libxml2-2.6.23
fontconfig-2.3.93
zlib-1.2.3
libpng-1.2.10
DirectFB--1.0.0
cairo-1.2.6
pango-1.16.0
Gtk+ - 2.10.13
My gtk+ configure options are :
./configure --host=arm-linux --build=i386-linux --prefix=/usr/gtkdfb
--with-gdktarget=directfb --without-libtiff --without-libjpeg
--disable-glibtest --disable-modules --disable-largefile
after that i cross compiled a helloworld program given in
gtk/examples/helloworld source tree which is given below .
#include <gtk/gtk.h>
static void hello( GtkWidget *widget,
gpointer data )
{
g_print ("Hello World\n");
}
static gboolean delete_event( GtkWidget *widget,
GdkEvent *event,
gpointer data )
{
g_print ("delete event occurred\n");
return TRUE;
}
/* Another callback */
static void destroy( GtkWidget *widget,
gpointer data )
{
gtk_main_quit ();
}
int main( int argc,
char *argv[] )
{
GtkWidget *window;
GtkWidget *button;
gtk_init (&argc, &argv);
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
g_signal_connect (G_OBJECT (window), "delete_event",
G_CALLBACK (delete_event), NULL);
g_signal_connect (G_OBJECT (window), "destroy",
G_CALLBACK (destroy), NULL);
gtk_container_set_border_width (GTK_CONTAINER (window), 10);
button = gtk_button_new_with_label ("Hello World");
g_signal_connect (G_OBJECT (button), "clicked",
G_CALLBACK (hello), NULL);
g_signal_connect_swapped (G_OBJECT (button), "clicked",
G_CALLBACK (gtk_widget_destroy),
G_OBJECT (window));
gtk_container_add (GTK_CONTAINER (window), button);
gtk_widget_show (button);
gtk_widget_show (window);
gtk_main ();
return 0;
}
now if i use gtk_button_new_with_label() in creating a button my program
crashes with just a blue screen blink for a second. i get the following
error, i am pasting the error msg here.
[root at ARMCore root]$ ./helloworld

Now if i use gtk_button_new() for creating a button the program doesnot
crashes but still i get
Gdk-CRITICAL **: gdk_drawable_set_colormap: assertion `cmap =
= NULL || gdk_drawable_get_depth (drawable) == cmap->visual->depth' failed
This is the output when i run the same helloworld application using
gtk_button_new()
[root at ARMCore root]$ ./helloworld1

I get a blue screen with a window and an empty button.
Now there are two things:
1) whatever is the case i get Gdk-CRITICAL **: gdk_drawable_set_colormap:
assertion `cmap
== NULL || gdk_drawable_get_depth (drawable) == cmap->visual->depth' failed.
2) I cannot create a button with a label.
Is there any problem in the way i am building my libraries?
Thanks
Jasdeep
