Re: [Visualpython-users] seg faulting

[John Z. <joh...@wa...>]

Hi,

I am talso rying to run Vpython on a 64-bit Ubuntu 12.04 and having this problem. I don't think it's the new NVIDIA driver per se causing the issue. What I have discovered is that python-visual works fine on a clean install (including updates). However, as I install other packages, the visual module eventually breaks. This happens during a lab install that includes lots of additional packages that I install en masse. I started installing packages one-by-one and testing after each install. I got about 1/2 way through and had installed everything that I thought could possibly be related; vpython still worked. Then I got impatient and installed all the rest. Naturally, it broke again. It seems to me some package is installing a tweaked version of a library (perhaps something in libboost???) that kills vpython.

I will have a lab assistant again starting next week, and I am going to have him go through package by package to see if we can find what's breaking the python-visual module.

Subject: [Visualpython-users] seg faulting

I've been a long time user of vpython for visualizing results of my simulations. However, this just started happening today:

<mailto:vis...@li...>andy@andyLab:~/fer$ python
Python 2.7.3 (default, Aug  1 2012, 05:14:39)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from visual import box
>>> box()
Segmentation fault (core dumped)
andy@andyLab:~/fer$

I suspect the issue has to do with the fact that I installed new NVIDIA graphics drivers about a week ago to install CUDA. I'm running Ubuntu 12.04 64 bit. Any ideas?
