Are you looking for general instructions or are you trying to optimize the rtems build?
To wrap the compiler using ccache, override the environment variables during the configuration: CXX='ccache gxx' CC='ccache gcc' waf configure The rtems manual does not advertise it, so it this may void your warranty: CC="ccache /home/user/quick-start/rtems/6/bin/sparc-rtems6-gcc" ./waf configure --prefix=$HOME/quick-start/rtems/6 The wafcache extension is a different system: if the wafcache.py is added to a project (it is not a default option yet), all build results (link, results, manual pages) become shareable using a filesystem directory or over the network. It is probably unnecessary to import it in rtems unless you are addressing a specific performance issue.
