## 4.7.3 Upgrading gcc

The `gcc` C and C++ compiler is used to compile software on your system, most importantly the kernel. The newest version of `gcc` is found on the Linux FTP sites. On `sunsite.unc.edu`, it is found in the directory `/pub/Linux/GCC` (along with the libraries). There should be a `release` file for the `gcc` distribution detailing what files you need to download and how to install them.
