Trouble Installing CUDA 2.2 Driver no gcc 4.3

We’ve been using CUDA 2.0 on:
But when we try to install CUDA 2.2:
I get this error:
No precompiled kernel interface was found to match your kernel; would you like the installer to attempt to download a kernel interface for your kernel from the NVIDIA ftp site (
I enter yes
I get this error
No matching precompiled kernel interface was found on the NVIDIA ftp site; this means that the installer will need to compile a kernel interface for your kernel.
I enter ok
I get this error
The CC version check failed:

The compiler used to compile the kernel (gcc 4.3) does not exactly match the current compiler (gcc 4.2). The Linux 2.6 kernel module loader rejects kernel modules built with a version of gcc that does not
exactly match that of the compiler used to build the running kernel.

If you know what you are doing and want to ignore the gcc version check, select “No” to continue installation. Otherwise, select “Yes” to abort installation, set the CC environment variable to the name of
the compiler used to compile your kernel, and restart installation. Abort now?

Now what do I do? Do I need to update to gcc 4.3? Could I continue here?
Thank You,

CC=/usr/bin/gcc-4.3 ./

This code solved my problem.

Thank you,
