+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 +$HOME/.buildroot-ccache+. It is stored
outside of Buildroot output directory so that it can be shared by
separate Buildroot builds. If you want to get rid of the cache, simply
remove this directory.
The cache is located in the directory defined by the +BR2_CCACHE_DIR+
configuration option, which defaults to
+$HOME/.buildroot-ccache+. This default location is 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+.
