This is not a bug you have. The octane demo has been explicitely built for Cuda 3.0 and NVidia didn't preserve upward compatibility.
What I mean is that you shouldn't rely on the installer itself to cleanup the previous install.
Once you're done with the install, create a cuda.conf file so you have the followng:
Code: Select all
lionel@pc-lionel:~$ cat /etc/ld.so.conf.d/cuda.conf
/usr/local/cuda/lib64
and then run
