I’ve installed CUDA on CentOS 5.4 x86_64, and everything appears to be OK. The current version of GCC on the system is 4.1.x.
I’m thinking about upgrading to GCC 4.4.0 using the gcc44 technology preview package. This might solve some problems that I am having with building PyCUDA.
If I upgrade the GCC version, will the CUDA installation need to be started from scratch? In other words, do I need to always make sure that the driver, toolkit, and SDK have been compiled against the version of GCC that is installed?
This is for a home system, so some experimentation is OK.
