Python-Visual on Ubuntu10.04 LTS

[Tyson D]

Ok I've seen a few people having a problem with Vpython on Lucid but none seem to be having my problem. When ever i type

python filename.py

i get this error message

################################################## ###############

and apt-get policy visual-python gives me this

What does filename.py contain? What does
python -c 'import visual'print?



and apt-get policy visual-python gives me this


I guess you mean
apt-cache policy python-visualThe version installed is fine.

[Tyson D]

the file usually contains

from visual import*
ball = sphere()

the cmd you suggested:

python -c 'import visual'

does nothing at all.

Ive also tried IDLE but when i write the above code it will simply crash.

[diesch]

I guess if you run the commands line by line using the python shell the error is thrown when you run
ball = sphere()

That looks like python-visual is fine but there are some problems with your graphic card using OpenGL.

But in the past ive had 9.04 and Vpython worked just fine(now im running 9.04 through a VM and it supports Vpython).

and yes when i run the code through python it gives me the same error message.

I get the same behaviour on my acer spire one and a nice grey sphere on my desktop so its definitely a videocard issue

Ignore my last comment, there is a package dependency bug. You need to install libgtkglextmm-x11-1.2-dev

Thanks man, I had the same problem and installing libgtkglextmm-x11-1.2-dev fixed it!
