ccache is a software development tool that caches the output of C/C++ compilation so that the next time, the same compilation can be avoided and the results can be taken from the cache. This can greatly speed up recompiling time.

Install ccache by running the following command:
make install clean -C /usr/ports/devel/ccachePrint This Post
