Installing PyOpenGL on Mac OS X 10.4.1

Update 2007/02/26

Mike Fletcher has been working on PyOpenGL 3, which uses ctypes instead of swig. As a result, installation and updating are a lot easier. See the SourceForge project page for more info, but here's a quick summary:

$ sudo easy_install PyOpenGL

You can also install and run the demos:

$ sudo easy_install PyOpenGL-Demo

Once they're installed, how do you get at them?

$ cd /Library/Frameworks/Python.framework/Versions/Current/lib/python2.5/site-packages/PyOpenGL_Demo-3.0.0a6-py2.5.egg/PyOpenGL-Demo/
$ cd redbook
$ python movelight.py

Each demo pops up in its own lovely, top-level window.

Original Post

After upgrading to Mac OS X 10.4.1 I decided to install Python 2.4.1. Python made a framework install with no problem. But I ran into a small problem trying to install PyOpenGL-2.0.1.09.


I kept getting compile errors complaining about an incomplete definition for st_atimespec, et al. (Here comes another batch of extremely long lines...)

In file included from /Library/Frameworks/Python.framework/Versions/2.4/include/python2.4/pyport.h:155,
                 from /Library/Frameworks/Python.framework/Versions/2.4/include/python2.4/Python.h:55,
                 from src/config.h:1,
                 from _configtest.c:6:
/System/Library/Frameworks/Kernel.framework/Headers/sys/stat.h:225: error: field 'st_atimespec' has incomplete type
/System/Library/Frameworks/Kernel.framework/Headers/sys/stat.h:226: error: field 'st_mtimespec' has incomplete type
/System/Library/Frameworks/Kernel.framework/Headers/sys/stat.h:227: error: field 'st_ctimespec' has incomplete type

What was odd was that the build process was trying to include sys/stat.h from .../Kernel.framework/Headers, instead of from /usr/include.


I modified config/darwin.cfg and removed /System/Library/Frameworks/Kernel.framework/Headers from the list of include directories, and thereafter PyOpenGL built and installed without error.


The examples ran, too :)


Here's the context diff for config/darwin.cfg. Apologies, again, for the long lines -- I've tried to escape them using trailing backslashes.
