It also doesn't work with GTK+ version 3, but that probably doesn't matter for you because GTK 3 isn't stable on Windows anyway. My suggestion would be to stick with Gtk+ 2.24 and don't use GtkGLExt, but it's up to you. Here's some sample code to setup OpenGL on a GTK+ widget. It runs on Linux (X11), Windows, and Mac (Cocoa). It does the bare minimum to get things going, but you can modify it to suit your needs. http://git.gnome.org/browse/grits/tree/src/gtkgl.c If you want to use OpenGL 4.2, that might be a reason to attempt GtkGLExt, since it tries to do all the extensions handling. > and i will use with it CUDA gpu programming but i need to setup > opengl 4 on gtk+ panel or canvas Sorry, I am not experienced with CUDA
