3 There are two ways to use ccache. You can either prefix your compilation
4 commands with ccache or you can let ccache masquerade as the compiler by
5 prepending /usr/lib/ccache to your $PATH environment variable. The first
6 method is most convenient if you just want to try out ccache or wish to
7 use it for some specific projects. The second method is most useful for
8 when you wish to use ccache for all your compilations.

10 You can also set CC and CXX like so,
11 export CC='ccache gcc' ; export CXX='ccache g++' to /etc/pkgmk.conf
12 But this method can break on some packages not expecting a space in
13 CC or CXX.
14
15 You might also want to change the ccache directory, using the CCACHE_DIR
16 environement variable. (I personally use
17 export CCACHE_DIR="/var/cache/ccache").
18
19 You may also want to use distcc as a backend to ccache by setting
20 export CCACHE_PREFIX="distcc"
21
22 Also if you plan to use this same cache between different crux versions and
23 compiler versions, you can do something like this
24 export CCACHE_COMPILERCHECK="%compiler% -dumpversion; crux"
25 to prevent cache errors.
