[pacman-dev] recommended usage of distcc/ccache
our wiki page is old. this is how i usesd distcc with makepkg from pacman2.x so i could switch using it with or without ccache: export MAKEFLAGS="-j6" export USE_FAKEROOT="y" export DISTCC="y" export DISTCC_HOSTS="localhost/4 192.168.0.25/2" # with ccache export CCACHE_PREFIX="distcc" export CC="ccache gcc" export CXX="ccache g++" # without ccache #unset CCACHE_PREFIX #export CC="distcc gcc" #export CXX="distcc g++" from the /usr/bin/makepkg script it should work even without that additional exports. but it seems to not work without using only that now with makepkg3: MAKEFLAGS="-j4" BUILDENV=(fakeroot distcc color ccache) DISTCC_HOSTS="localhost/2 192.168.0.6/2" also JGC pointed us to not use the export commands for ccache: http://bugs.archlinux.org/task/6957?histring=ccache Can you please tell us what it the recommended best working config for both options? and maybe please update both wiki pages for ccache and distcc. Thanks Andy

makepkg 3 has built in support for ccache. It can be disabled by packages that do not cooperate with it by placing !ccache in the options array (or the deprecated noccache). -Dan

ccache works well with makepkg3. but i couldn't get distcc to work again. any hints? Andy
having BUILDENV=(fakeroot distcc color ccache) and DISTCC_HOSTS="localhost/2 192.168.0.90/2" i still get this: distcc[25671] (dcc_get_hostlist) Warning: no hostlist is set; can't distribute work distcc[25671] (dcc_build_somewhere) Warning: failed to distribute, running locally instead AndyRTR

ok, DISTCC_HOSTS is simply not exported. also MAKEFLAGS and maybe more. can you check again why you have removed all the "export" in front of the variables in /etc/makepkg.conf? Andy

Never do it that way! If you compile a kernel for example you expect everybody to have ccache installed. Rather modify PATH to have /usr/lib/ccache/bin before /usr/bin. The symlinks in ccache are made to work around this kind of problem. Cheers, -Y
