[Visualpython-users] OpenGL initialization failure

[Jutta Luettmer-S. <ju...@ne...>]

Good evening,

I tried to install VPython on a linux workstation (Fedora Core 4, python 
2.3.4). After some trouble, the "idle" window opens now and imports from visual 
(>>> from visual import *    works fine) however, it has trouble finding 
OpenGL. For example,

>>> floor = box(length=4, height=0.5, width=4, color=color.blue)
OpenGL initialization failed.
   Unable to create OpenGL display widget

At the same time, the error message

Xlib:  extension "GLX" missing on display ":0.0".
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkWidget'

is displayed in the window from which "vpython" was called.

I've tried recompiling vpython (using the suggestion under "morelinux") but 
that doesn't seem to help. I'd be grateful for any help.
