+
+ <p><a href="http://ccache.samba.org">ccache</a> 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

+ pre-existing object files. When doing almost identical builds from
+ scratch a number of times, it can nicely speed up the build

+ in <code>Build options</code>. This will automatically build
+ <code>ccache</code> and use it for every host and target
+ compilation.</p>
+
+ <p>The cache is located
+ in <code>$HOME/.buildroot-ccache</code>. 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.</p>
