Yes, I will generate a full build log and attach it to this mail.

You are linking against following libraries:
gtkglext-x11-1.0 GLU GL gtk-x11-2.0 gdk-x11-2.0 atk-1.0 gdk_pixbuf-2.0 
pangocairo-1.0 pango-1.0 cairo gobject-2.0 gmodule-2.0 glib-2.0 Xext X11 Xi 
Xmu freetype expat m dl

and your binary says:
gtkglext-x11-1.0 GLU GL gtk-x11-2.0 gdk-x11-2.0 gobject-2.0 glib-2.0 freetype 
expat m gdkglext-x11-1.0

The most important difference is gdkglext-x11-1.0. So adding
 -lgdkglext-x11-1.0 fixes the problem as this is the library which provides 
these symbols and not gtkglext-x11-1.0 (which is a "layer" above it).

Best regards,
