 +====== CCache ======
 +Using ccache can speed up rebuilds a lot. When set up, it caches the binary objects as applications are built, and later it copies those objects back, instead of having to recompile them.
 +
 +Slackware comes with ccache.
 +
 +To start using it, get root and:
 +
 +<​code>​
 +cd /​usr/​local/​bin
 +
 +ln -s /​usr/​bin/​ccache cc
 +ln -s /​usr/​bin/​ccache c++
 +ln -s /​usr/​bin/​ccache gcc
 +ln -s /​usr/​bin/​ccache g++
 +</​code>​
 +
 +To set a max size for the cache:
 +
 +<​code>​ccache -M 5G</​code>​
 +
 +That sets a max size of 5GB in /​root/​.ccache
 +
 +You obviously need to set it for your needs and available space.
 +
 +To see some info about ccache, do:
 +
 +<​code>​ccache -s</​code>​
 +
 +To temporarily turn it off:
 +
 +<​code>​export CCACHE_DISABLE=1</​code>​
 +
 +If that fails to work then just move the symlinks out of /​usr/​local/​bin
 +
 +Don't forget to read the man page.
