HOWTO: FreeBSD with CCACHE
install ccache port or add a package:
Code:
# cd /usr/ports/devel/ccache && make install clean # pkg_add -r ccache Code:
CC=/usr/local/libexec/ccache/world-cc CXX=/usr/local/libexec/ccache/world-c++ Code:
# set ccache varibles setenv PATH /usr/local/libexec/ccache:$PATH setenv CCACHE_PATH /usr/bin:/usr/local/bin setenv CCACHE_DIR /var/tmp/ccache setenv CCACHE_LOGFILE /var/log/ccache.log # set ccache temp size to 512MB (default 1GB) if ( -x /usr/local/bin/ccache ) then /usr/local/bin/ccache -M 512m > /dev/null endif ccache can be shared between several computers the same as ports tree for example, check man ccache for more info. ADDED 2007.2.15: example ccache stats from my box. Code:
% ccache -s cache directory /var/tmp/ccache cache hit 18562 cache miss 102820 called for link 9824 multiple source files 75 compile failed 1610 preprocessor error 1446 not a C/C++ file 3747 autoconf compile/link 16982 unsupported compiler option 511 no input file 6698 files in cache 49631 cache size 464.3 Mbytes max cache size 512.0 Mbytes comparasion of buildworld times with and without ccache: Code:
# without ccache make -j1 buildworld 4148.38s user 937.02s system 97% cpu 1:27:00.40 total # with ccache make -j1 buildworld 1043.30s user 703.76s system 88% cpu 32:50.02 total Code:
% cd /home/${USER} % rm -rf .ccache % ln -s /var/tmp/ccache .ccache % ls -l .ccache lrwxr-xr-x 1 ${USER} ${USER} 15 Dec 19 15:20 .ccache -> /var/tmp/ccache % ccache -s cache directory /var/tmp/ccache cache hit 165292 cache miss 327142 called for link 38002 multiple source files 216 compile failed 5182 preprocessor error 4934 couldn't find the compiler 1 not a C/C++ file 26249 autoconf compile/link 52665 unsupported compiler option 1379 no input file 23289 files in cache 79438 cache size 530.2 Mbytes max cache size 512.0 Mbytes % sudo ccache -s cache directory /home/vermaden/.ccache cache hit 165292 cache miss 327142 called for link 38002 multiple source files 216 compile failed 5182 preprocessor error 4934 couldn't find the compiler 1 not a C/C++ file 26249 autoconf compile/link 52665 unsupported compiler option 1379 no input file 23289 files in cache 79438 cache size 530.2 Mbytes max cache size 512.0 Mbytes
