How to colorize shell while using rosmake?

edit

Are you aiming specifically at rosmake (i.e. not make in a ROS package)?

The normal make with CMake is colored from CMake and to get colored warnings and errors from g++ I use colorgcc.

1. Install colorgcc by sudo apt-get install colorgcc
2. Define a directory where you will have executables in your path, e.g. $HOME/bin (create bin in your home directory)
3. Add this directory to your path, i.e. export PATH=$HOME/bin:$PATH. Prefereably put that line in your .bashrc or similar, so you only have to do this once
4. In that directory create symlinks to colorgcc, i.e.:

    ~/bin$ ln -s /usr/bin/colorgcc c++
    ~/bin$ ln -s /usr/bin/colorgcc g++
    ~/bin$ ln -s /usr/bin/colorgcc gcc
    ~/bin$ ln -s /usr/bin/colorgcc cc

For CMake only the first line is required.
