There's a sample of usage here (known to work on Win32 and Linux with latest CVS HEAD):
http://pyopengl.cvs.sourceforge.net/pyopengl/OpenGLContext/tests/shaderobjects.py?view=markup The key information you seem to be missing are that the Python version has a simpler API and that you have to pass an array (list) of strings, not just a single string to the compilation function. The count and length (array of lengths) parameters are pulled from the list-of-strings you pass. HTH, Mike -- ________________________________________________ Mike C.
