Ubuntu: Does CUDA work on 12.10?



Question:

Has anyone tryed CUDA on Ubuntu 12.10 with Blender or another programm? In the last beta of Quantal CUDA wasn't working. I would like to update from 12.04 to 12.10 final but only if CUDA still works. Is there someone who already has experience with this? Thanks


Solution:1

The installation of CUDA 5.0 fails on ubuntu 12.10 :

Solution:2

First install gcc-4.4 and g++-4.4 then make a symlink of sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.4, it is not too clean but probably you should delete first the symbolic link of /usr/bin/gcc.


Solution:3

Simplest solution is:

It detects then cuda gpu without any problems. (Of course assuming that you have propersly installed latest propietrary nvidia drivers)

Yep, i know that is not that elegant as making it work when installed from repo or ppa, but for me most important is that works, so i can use blender and cycles.

If you dont need the cuda toolkit (for develping etc) i think it is acceptable workaround for you too.
