Hello,
  Great hack, got it working no problem now.  One side question,  gluBuild3DMipmaps works without a hitch, but when I call bool(glTexImage3D) I get "False" back. glGetString(GL_VERSION) returns 2.0.1 so supposedly teximage3d is supported on gl > 1.2.  Am I missing something here?
  Thanks
  Andrew

There is, though it feels a bit hacky and has AFAIK never been tested.
Here's an example where I make the GLU DLL a completely unrelated
library (so there will be no GLU functionality at all):

>>> import ctypes
>>> glu = ctypes.CDLL( '/usr/lib/libFLAC.so' )
>>> platform.GLU = glu
>>> from OpenGL.GLU import *
>>> gluGetString
<OpenGL.platform.gluGetString object at 0x2aaaabc82f10>
>>> gluGetString( GLU_VERSION )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"/var/pylive/src/OpenGL-dev/OpenGL-ctypes/OpenGL/platform/__init__.py",
line 186, in __call__
    self.__name__, self.__name__,
OpenGL.error.NullFunctionError: Attempt to call an undefined function
gluGetString, check for bool(gluGetString) before calling

(You will need to use WinDLL, not CDLL for win32).  You may want to use
OpenGL.platform.ctypesloader.loadLibrary( ctypes.windll,
path_to_your_library ) instead of the bald ctypes operations, as older
ctypes versions should be supported with that function.

Good luck,
Mike
