Details

The latest kernel26 ABS package can not take advantage of distc compiling. The reason for this is that the kernel Makefile will redefine $CC. The only way to force a user specified CC is to change the 'make' line the PKGBUILD file.

the change should be from:

make {target}

to:

make CC=$CC {target}

This will force make to use the environment variable $CC
This task depends upon

this is actually not 100% the case. if you enable the distcc feature in makepkg.conf like this:

====================================================================
#-- DistCC: a distributed C/C++/ObjC compiler (modify MAKEFLAGS too)
export DISTCC="y"
#-- A space-delimited list of hosts running in the DistCC cluster
export DISTCC_HOSTS="192.168.3.7"
====================================================================

/usr/bin/makepkg does this on line 623:
====================================================================
export PATH=/usr/lib/distcc/bin:$PATH
====================================================================

which makes the link on distcc called gcc the first available gcc binary. this works perfectly.

anyway, if you override the CC in the kernel's Makefile (like: distcc gcc) you will break building modules for everyone who does not have distcc installed.

Re-opened by Casey McGinty:

The export path does not look correct? The arch distcc package does not create /usr/lib/distcc/bin directory.

Makepkg says:

[ -d /usr/lib/distcc/bin ] && export PATH=/usr/lib/distcc/bin:$PATH

The arch distcc package installs stuff into /usr/bin
So, this line doesn't hurt at all, but it doesn't do anything useful either from the looks of things.

still valid?
Comment by Alexander Baldeck (kth5) - Friday, 09 March 2007, 15:08 GMT
it is still valid. distcc packages needs links to /usr/bin/distcc in /usr/lib/distcc/bin to get it to work without using `distcc gcc` which would hurt! :)

attached patch should help.

oops... sample taken from ccache, obviously the links are made wrong. see this patch instead.
