[pacman-dev] recommended usage of distcc/ccache

[Andreas Radke]

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:

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
