Installing GCC 4.4 on CentOS 5

If you’re running CentOS, you may find yourself frustrated that you have GCC 4.2 or older, when you need to be running at least 4.3 for some features – for example, if you want to compile HipHop for PHP.

Never fear, you don’t need to compile a compiler from source!

As well as the gcc RPMs in the repository, there are also a set for GCC 4.4, appropriately enough named gcc44 and you can install them in the usual way.

yum install gcc44 g++44
