Hi. I'm experiencing segmentation fault on ubuntu. As opposed to most other
ubuntu-seg-fault post, my ubuntu is a 32 bit.
The minimum program that makes it crash is :
from OpenGL.GLUT import *
glutInit( ' ' )
glutInitDisplayMode( GLUT_SINGLE )
Any body got an idea ?
Glx gear is running without any problem. Here is some informatqion that
might be usefull (maybe too much information)

Hmmm... I tried a live cd and the segfault dissapeared... This means it have something to do with the configuration of the computer :S The live cd was hardy (8.04) and the fix install is ibex (8.10, upgraded from hardy) Any body have an idea what need to be configured ? thanks ªŁ€× On Tue, Nov 11, 2008 at 3:56 PM, Alexandre Lacoste <alex.lacoste.ml@ gmail.com> wrote: > Hi.

Not really. I'm on a Kubuntu 32-bit Hardy machine here, script executes without problems. I have FreeGLUT 3 installed if that helps you. If you have gdb, you could try doing a gdb python core on the corefile to see where the actual crash occurs. If you do an import pdb; pdb.set_trace() and step into everything you should at least be able to see what is going into the C code as values as the crash occurs. Out of curiosity, if you switch to GLUT_DOUBLE, does it still crash? I wouldn't be all *that* surprised to discover that something wasn't being tested in single-buffered mode. Good luck, Mike -- ________________________________________________ Mike C. Fletcher Designer, VR Plumber, Coder http://www.vrplumber.com http://blog.vrplumber.com |
