Re: [Visualpython-users] Building vpython 5.4 in Ubuntu 10.10

[Patrick S. <pat...@gm...>]

Never mind, I tried compiling again, this time doing it from the source
directory rather than creating a new directory, and I got it to work and
install properly.  I also had to install the Polygon, fonttools, and
ttfquery modules to get visual to load (I missed that part in the
INSTALL.txt instructions last time).

Unfortunately I still have the same problem with the version I compiled
as I was having with the python-visual package from ubuntu's
repositories.  When I open a vpython window by doing say:
import visual
visual.sphere()
I get the error message:

i915_program_error: Exceeded max instructions (318 out of 123)

and vpython runs extremely slow (interacting with the mouse takes 5-10
seconds to respond).  3D graphics seem to work very well otherwise on
the computer, so I thought it might have been a problem with ubuntu's
version of visual python, but I guess it must be something else.  After
googling, I found some people with the same problem:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=598896
but nobody seems to have found a solution.
