Found the source of SegFaults on AMD + FreeGLUT

So the source of the segfaults that I'm seeing on fglrx and FreeGLUT on Kubuntu 14.04 has come to light. It's a known issue with the registration of FreeGLUT and fglrx at-exit handers (at the C level). You can work around it in your own code with PyOpenGL 3.1.0b3+ (which ...

PyOpenGL test_core on 2.7, 3.3 and 3.4

I just finished doing a clean test run across those 3 releases of Python with each of the 8 major config flags on/off (i.e. 48 runs of the test suite). As expected, almost all of the failures were in Python 3.x, and mostly related to unicode, where COPY_ON_ERROR generated failures when a ...

Ubuntu Configuration for Inspiron 15r Running Hot

So you have a Dell Ubuntu 14.04 Laptop and it is running way too hot. You can configure it to run at a reasonable level using i8kmon. As with anything heat related, be careful. If you miss-configure the machine you are likely to wind up with a fried machine!

You create a file called ...

Auto-generating Output Declarations

So the good news is that I've now got far more PyOpenGL output parameters automatically wrapped such that they can be passed in or automatically generated. That drops a *lot* of the manually maintained code. OpenGLContext works with the revisions, but the revision currently does *not* support non-contiguous input arrays (basically the cleanup included ...

Enums and Output Variables

Walter on PyOpenGL Users pointed me at the chromium "regal" tool, which has a table of constant definitions for output parameter sizings. I have a similar mechanism inside PyOpenGL's source code, so I parsed the table out of regal and used it to spot and plug gaps in the PyOpenGL table. The regal stuff ...

So close on py2exe with PyOpenGL

I played with getting a py2exe executable created from PyOpenGL today, and it is very close to working.  The basics:

from distutils.core import setup
import py2exe
import glob, os
import OpenGL
data_files = [
    (
        os.path.join('OpenGL','DLLS'),
        glob.glob( os.path.join( os.path.dirname( OpenGL.__file__ ), 'DLLS', '*.*' ))
    ),
]

if __name__ == "__main__":
    setup(
        windows=['shader_test ...
