Did somebody (Warren?) look into this? Could anybody reproduce it (i.e.
running examples/devel/gl01.py)? Or is this just a problem on Debian
GNU/Linux?
thanks,
Michael

I would like to use pymol with python-opengl script. On my
laptop I use
pymol-0.86 width redhat 8.0. This package contains a lot of python
example script, for example example/devel/gl01.py script. Running this
script I have got a simple coordinate system displayed on the screen
(the script is attached), while pymol reports:
OpenGL based graphics front end:
GL_VENDOR: Mesa project: www.mesa3d.org
GL_RENDERER: Mesa GLX Indirect
GL_VERSION: 1.3 Mesa 4.0.4
Executive: object gl01 created.
Using the debianized version of pymol-0.90 with debian-sid on my
workstation, I have got the following error message:

I don't know whether I have not installed something, or it is a bug in
the debianized pymol-0.90, or this error come from the NVIDIA opengl
driver.
I'm really happy, if you can help me resolving this discrepancy.

Is there a reason why these libraries are not defined in pyogl_libs?
With that fix, examples/devel/gl01.py works fine. gl02.py gl03.py still
fail though, with this error message:
Executive: object gl02 created.

Digging a bit into contrib/pyopengl[1], I found that glVertexPointer
will only get exported when NUMERIC is defined. As you can see from the
patch above, _PYMOL_NUMPY is not defined and thus neither will be
NUMERIC. If I uncomment that line above, I get this error while trying
to build pymol:

Finally, when I add HAVE_NUMERIC_ARRAYOBJECT_H to the defines in
setup.py, pymol compiles fine[2] but gl02.py still fails:

That's where I stopped debugging stuff, can anybody help me?

[1] btw, is this the standard pyopengl module? Why is it shipped with
