Re: [Visualpython-users] Segmentation Fault

[Bruce S. <bas...@nc...>]

It's certainly not obvious what the problem is, but here are two small ideas:

1) Sometimes problems of this kind stem from a need to update the
graphics drivers. I'm inclined to think that's not your problem,
because you crash just trying to import visual, before creating any
objects.

2) I see that the visual machinery is in
/usr/lib/python2.6/site-packages. I don't know anything about
Arch-Linux, but on Ubuntu there was a recent change involving
dist-packages as opposed to site-packages. Is it conceivable that your
builds have put the newly compiled files somewhere not in
/usr/lib/python2.6/site-packages, but there is something in
/usr/lib/python2.6/site-packages that is corrupted?

Curious that VPython works on one of you machines but not on two others....
