How to install the latest g++ version on CentOS

Question

I tried yum install gcc-c++, however, the repos have an old version (4.1) which causes lots of problems and stops me from building a library. I would like to update it to latest. How can I do that?

Solution

You're referring to CentOS 5.x, based on the version number in your post. You can upgrade to gcc44-c++, which is a slightly-newer version 4.4. This is available in the base repo using yum.

Try yum install gcc44-c++.

Once installed, the executable you'd use will be /usr/bin/g++44 instead of /usr/bin/g++.
