-==Requirements==
-The following seems to be out of date for my Ubuntu setup.  My suggestion would be to look
-at the latest info for distcc and follow the instructions from there. Make sure the different
-machines have the same software.  DAS
- distcc
- ccache
-Install distcc on all machines taking part in the compilation. List them in <nowiki>~/.distcc/hosts</nowiki>:
- localhost
- pc1.mynet.org
- pc2.mynet.org
-The first machines listed are given higher priority -- place 'localhost' as you see fit.
-Set the environment variables CCACHE_PREFIX, CXX and CC:
- export CCACHE_PREFIX="distcc"
- export CXX="ccache g++"
- export CC="ccache gcc"
- ./configure <options>
-Compile using the <nowiki>-j<simultaneous-jobs></nowiki> flag, two jobs per CPU available, i.e. for 5 machines
- make -j10
