Faster FreeBSD Ports Collection Compiles with ccache and tmpfs
ccache is a compiler cache. It speeds up recompilation by caching previous compilations and detecting when the same compilation is being done again. Sounds like something you would want to have if you’re compiling most software from source, as I do. As a bonus, we’re setting the work directory to a ramdisk, so all compile activity is done in memory instead of on disk. Here’s how you do it.
cd /usr/ports/devel/ccache make install clean
Add a couple of lines to
WRKDIRPREFIX=/ram CCACHE_DIR=/var/cache/ccache WITH_CCACHE_BUILD=yes
/ram folder for the
tmpfs mountpoint. We’re using a size of 2 GB here, adjust to taste:
mkdir /ram echo 'none /ram tmpfs rw,size=2147483648 0 0' >> /etc/fstab mount /ram
Set some defaults in
max_size = 5G cache_dir = /var/cache/ccache
Enjoy faster compiles.
