Your patch works fine for me, thanks!
However, I don't see any performance gain when using ccache:
Number of cache hits is very low.
I need to understand this...
Make sure you have the following environment variables set:
CCACHE_HASH_COMPILER=1 (2.4)
CCACHE_COMPILERCHECK=content (3.0+)
It's unnecesary as long as he has
CC=/usr/local/libexec/ccache/world-cc
CXX=/usr/local/libexec/ccache/world-c++
in make.conf because these files already take care about this:
#!/bin/sh
unset CCACHE_PATH
export CCACHE_COMPILERCHECK=content
exec /usr/local/libexec/ccache/c++ "$@"
I don't know if following solution is a dirty hack or proper approach but I
found this on list some months ago and it works for me. Here's a part of my
make.conf which deals about world building (look at CC:= and CXX:= difference):
# default build settings for base system
.if ${.CURDIR:M*/usr/src/*} || ${.CURDIR:M*/usr/obj/*} &&
!defined(NOCCACHE)
#CC=/usr/local/libexec/ccache/world-cc
#CXX=/usr/local/libexec/ccache/world-c++
CC:=${CC:C,^cc,/usr/local/libexec/ccache/world-cc,1}
CXX:=${CXX:C,^c\+\+,/usr/local/libexec/ccache/world-c++,1}
CFLAGS=-O2 -pipe
COPTFLAGS=-O2 -pipe
.endif
