Re: [Visualpython-users] segmentation fault on Fedora 16.

[Yann G. <ygo...@is...>]

We found what the problem was.  

If you have the mesa package installed, all the libraries will be
installed in /usr/lib64.  If you install the nvidia package of old, the
libraries will be installed in the same /usr/lib64.  Thus libGL.so would
either the mesa one or the nvidia one depending on the order of
installation.  

VPython is looking for libGL.so.  In my case, it was finding the one in
/usr/lib64/ (the mesa one).  This one does not support the right call
hence the segmentation fault.  To fix it, just pointing it to the right
library worked.  In command line parlance:
    $ cd /usr/lib64
    $ sudo mv libGL.so.1.2 MESA_libGL.so.1.2
    $ sudo ldconfig
    $ sudo ln -si nvidia/libGL.so.1 libGL.so
    $ ipython
    In [1]: from visual import *             
    In [2]: s = sphere()
    [... Sphere appears ...]
