How to set up your environment on TUM-Rosie for distcc and ccache

• Get the packages installed

apt-get install distcc ccache

• Set up the environment in your ~/.bashrc :

export CCACHE_PREFIX=distcc
export DISTCC_HOSTS='username@amy/8:/usr/bin/distccd username@leela/8:/usr/bin/distccd'
export ROS_PARALLEL_JOBS="-j18"
export PATH=${HOME}/local/bin:${PATH}

• Create the following links in your ~/local/bin:

cd ~/local/bin
ln -s /usr/bin/ccache cc
ln -s /usr/bin/ccache c++
ln -s /usr/bin/ccache gcc
ln -s /usr/bin/ccache g++

• Make it faster by activating ssh connection caching. Add this to ~/.ssh/config :

Host *
  ControlMaster auto
  ControlPath ~/.ssh_tmp/master-%r@%h:%p

• Create the temporary ssh directory:

mkdir ~/.ssh_tmp

• Make sure you have your ssh-agent running, and that you can log in to amy without a password
• Test with your favorite compile! You should see compilers running on amy and leela.
