|Using +ccache+ in Buildroot
|http://ccache.samba.org[ccache] is a compiler cache. It stores the
|object files resulting from each compilation process, and is able to
|skip future compilation of the same source file (with same compiler
|and same arguments) by using the pre-existing object files. When doing
|almost identical builds from scratch a number of times, it can nicely
|speed up the build process.
|+ccache+ support is integrated in Buildroot. You just have to enable
|+Enable compiler cache+ in +Build options+. This will automatically
|build +ccache+ and use it for every host and target compilation.
|The cache is located in +$HOME/.buildroot-ccache+. It is stored
|outside of Buildroot output directory so that it can be shared by
|separate Buildroot builds. If you want to get rid of the cache, simply
|remove this directory.
|You can get statistics on the cache (its size, number of hits,
|misses, etc.) by running +make ccache-stats+.
