[PyOpenGL-Users] Exception when importing GLU

[Aki K. <pyo...@ak...>]

I have PyOpenGL-3.0.0b6 as packaged in Fedora 9. I started to get this 
exception some time ago. Maybe I updated something, maybe I didn't - can't 
remember. However now I started to look into it more closely and I came up 
with a minimal test program that can be used to reproduce this. Here it is:


import pygame
pygame.init()
screen = pygame.display.set_mode([800, 600], pygame.OPENGL | pygame.DOUBLEBUF)
from OpenGL.GL import *
from OpenGL.GLU import *


As you can see I'm also using pygame here. The exception happens on the last 
line where importing GLU. The traceback is on the end of this post.

I can fix this problem by moving the OpenGL import lines before creating the 
display. Maybe the example script is all wrong and I shouldn't be doing it 
this way. Meaning it might be just stupid to create the screen before 
importing all the OpenGL stuff. But anyway I wanted you to know this.

So this is not a show stopper for me but I'm just reporting this if the 
developers want to do something about it. Maybe handle the exception in some 
way.

Thanks for your attention,
Aki
