I have just installed Fedora 13 (x86_64) on a Dell D830 laptop and all went well except for Nvidia driver update.
I also ran into difficulty building the CUDA SDK due to weak declarations error with GCC 4.4.
A work-around was posted in this forum:
I resolved this on Linux Mint by installing GCC 4.3. How do I do that on Fedora 13?
yum search gcc-4.3 didn't turn anything up. Nor did a search for gcc43.
