Ccache has installed links for the following compilers
|
|
%%CCACHE_COMPILERS%%
|
|
in %%PREFIX%%/%%CCLINKDIR%%
|
|
|
|
!!! WARNING !!!
|
|
Please make sure you have the compiler installed before you do this or your
|
|
build will fail because it will not be able to find the compiler.
|
|
|
|
Any time you change CC/CXX you need to reinstall devel/libtool15 or you
|
|
will run in to problems.

Ccache's default cache size is 1GB and this is larger than the default size of
|
|
the root partition (/) on FreeBSD. To over come this you may specify a new
|
|
cache location on a different partition with the following examples.
|
|
|
|
For Korn/Bourne shells Add the following to /etc/profile:
|
|
export CCACHE_DIR=/usr/.ccache
|
|
|
|
For csh/tcsh Add the following to /etc/csh.cshrc
|
|
setenv CCACHE_DIR "/usr/.ccache"
