I just reinstalled devel/ccache to test this. The options to create
links to clang and llvm were turned on in the port. My old settings in
/root/.cshrc were uncommented:
setenv PATH /usr/local/libexec/ccache:$PATH
setenv CCACHE_PATH /usr/bin:/usr/local/bin
setenv CCACHE_DIR /usr/.ccache
setenv CCACHE_COMPRESS yes
The last two are additions. (I found that compression helped fit more
files in the same space without measurably slowing down the build.)
In /etc/make.conf, I added this:
.if (!empty(.CURDIR:M/usr/src*) || !empty(.CURDIR:M/usr/obj*))
.if !defined(NOCCACHE) && exists(/usr/local/libexec/ccache/world/cc)
CC:=${CC:C,^cc,/usr/local/libexec/ccache/world/cc,1}
CXX:=${CXX:C,^c\+\+,/usr/local/libexec/ccache/world/c++,1}
.endif
.endif
This is on 10.1-STABLE. make(1) changed a while back, so very old
versions of FreeBSD might have errors with those.
I logged back in as root and started a buildworld, and see this:
/usr/local/libexec/ccache/world/cc -m32 ...

You're welcome, Steve. :)
