Robert,
Where (what file) do I do this?
I think it's easier to do this at the root prompt:
[root@mybox root]#export CC=gcc32
then run the NVidia installer. Works for me.
Yeah it could be shortened to
[root@mybox root]#export IGNORE_CC_MISMATCH=1...
I have to do this because I get an error saying the compiler used for the kernel is different than the current installed version...
