gtkglarea + gtk-2.0. segfault

[Samuel Berthelot <samuelberthelot yahoo fr>]

Here is what I get when I compile my program that uses
gtk-2.0 and the gtkglarea widget:


gcc -Wall -ggdb -I/usr/include/gtk-2.0
-I/usr/lib/gtk-2.0/include -I/usr/include/atk-1.0
-I/usr/include/pango-1.0 -I/usr/X11R6/include
-I/usr/include/freetype2 -I/usr/include/glib-2.0
-I/usr/lib/glib-2.0/include -o exe parseur.o

/usr/local/lib/libgtkgl.so: undefined reference to
`gtk_widget_push_visual'
collect2: ld returned 1 exit status
make: *** [exe] Erreur 1


So to get over this I've installed the version 1.2.3
of gtkglarea (I had the 1.2.2) and now it compiles OK
But then I get a segmentation fault at execution. When
I use gdb I have the following :

75        glarea = create_glarea ();
(gdb) n

Program received signal SIGSEGV, Segmentation fault.
0x40703487 in XVisualIDFromVisual () from
/usr/X11R6/lib/libX11.so.6
(gdb) n

To be more precise it crashes here:

 int attrlist[] = {
    GDK_GL_RGBA,
    GDK_GL_DOUBLEBUFFER,
    GDK_GL_DEPTH_SIZE, 1,
    GDK_GL_NONE
  };


  if ((glarea = gtk_gl_area_new(attrlist)) == NULL) { 
 
CRASH
    g_print("Error creating GtkGLArea!\n");
    return NULL;
  }

Does someone have any idea why ???
Thanx
Sam
