Colorgcc

1. install colorgcc, with your distribution package manager, by downloading it on the official webpage http://schlueters.de/colorgcc.html, or by downloading my improved version (from the Gentoo version, submitted at http://bugs.gentoo.org/show_bug.cgi?id=291060) : colorgcc, colorgccrc
2. make sure ~/bin path is in your $PATH variable before /usr/bin
3. place symlinks in ~/bin/:

   cc  -> /usr/bin/colorgcc
   gcc -> /usr/bin/colorgcc
   g++ -> /usr/bin/colorgcc
   c++ -> /usr/bin/colorgcc

4. create a ~/.colorgccrc file, and define inside the location of the real cc, gcc, g++ binaries:

   /usr/bin/cc, gcc, g++
