Gtk_MenuFactory in gtk--?

[Marsel Osipov <marsel lex infi net>]

Hello all.
    I was wondering if anyone have had any experience setting up
Gtk_MenuFactory under gtk--?  I know that at this momment,  you can not
connect menus from menufactory to C++ member functions.  But I can not
even create the menubar.  Can anyone provide code example?   I am
attaching my example prog.  Would anyone please tell me what am I doing
wrong?

Also, have anyone had any luck compiling gtkGL-0.8?  When I ./configure,
it tells me that it can not find GL, gdk, and gtk libraries, but they
are in the LD_LIBRARY_PATH...



Thank you.
