[PyOpenGL-Users] Shader Support OS X

[Steven W. <st...@li...>]

I am testing a PyOpenGL install on OS X vr 10.4 and have run in to some 
trouble with the OpenGL shader implementation in an example written for 
3.X. The Error is included below along with some information about the 
system it is currently running on.


python shader_test.py  is available at 
http://storage.sureal.cc/python/shader_test.  As a side note I am able 
to run http://storage.sureal.cc/python/Works.zip.  Maybe a more 
experienced user can help identify the major differences between the two 
programs.

I am currently using the MacPorts project for my python installs.  XCode 
2.5 is installed on the system.  I used the py25-openGL build which is 
PyOpenGL version 3.0.0b5.  Yesterday I manually installed Python 2.5 and 
PyOpenGL 3.0b5 and ran in to the exact same error.  I wanted to make 
sure that I did not cause the problem with an abundance of possible lib 
conflicts from the install being old. So this morning I reinstalled OS X 
and cleaned off the HDD.  The install is up to date now with only XCode 
2.5, MacPorts, and PyOpenGL installed.  MacPorts installs all of its 
files in /opt/local.  The environment when the error was received was.
