[PyOpenGL-Users] Problems with simple pyopengl program

[James G. <ja...@ja...>]

Hi everyone,
I'm trying to get a very very simple pass-through shader to work in
pyopengl. I compiled and tested a simple C program, available here:

This program works exactly as expected -- a red plane is drawn, completely
covering the screen.

I tried to make the *exact* duplicate of this C program here:
http://pastebin.com/dYbbXTY1
This apparently does not work. Only the gray glClear color is displayed,
and the two triangles are never drawn.

Any insight into why this isn't working?
