1.2 progress showstopper: docs on pyglet architecture

[anatoly techtonik]

I'm trying to understand what are capabilities of my system, is it supported by pyglet and what is required to make it work, but..

Attempt to run tools/gl_info.py gives a traceback:

What steps will reproduce the problem?
1.hg clone https://code.google.com/p/pyglet/
2.cd pyglet
3.PYTHONPATH=. python tools/gl_info.py 

Paste in the traceback or error message:
...

File "/home/user07/pyglet/pyglet/gl/glu_info.py", line 92, in set_active_context

    asstr(cast(gluGetString(GLU_EXTENSIONS), c_char_p).value).split()
NameError: global name 'gluGetString' is not defined

Full info is here - http://code.google.com/p/pyglet/issues/detail?id=541

I'd like to fix the problem, but must admit I am not an OpenGL expert, and without high-level overview of pyglet architecture (and enough time to reverse it myself) it's really hard to get started. If anyone can come up with a good post about ties of pyglet with OpenGL subsystems - it will surely be appreciated by many Python developers, who are also potential pyglet users (+1 if you agree).

You'll need to get the gl and glu header packages; in ubuntu based
distros they usually end -dev.

HTH,
Adam.

Thanks. It seems I've run some generator from tools/ and it cleaned the contents of pyglet/gl/glu.py - it would be nice if this generator warned about missing header beforehand.
