In order to install the Eclipse CDT in the latest edition go to [eclipse.org] and look for the C/C++ development package. Depending on the Centos you're running you need to choose either the 32 bit or the 64 bit version for Linux.
To determine which version you need issue:
$ uname -p
expect something like this:
for a 64 bit machine.
In order to install the downloaded package first move it to /opt, then issue:
$ tar zxvf eclipse<package-name>
to unpack the package.
Create an entry in the menu if needed How to install an application for all users.
