As some of you know, (Hi, Mike!) I have a new box. Its hostname is
newbox. I am bringing up Gentoo on it. It's reasonably fast. It
"sort of" has two CPUs. (A Pentium 4 w/ hyperhtreading shows up as two
CPUs in Linux.)
I have another reasonably fast box, the dual Athlon box I use for work.
Its hostname is tivopc. It has to run RedHat 7.2 because that's what
TiVo development works on.
I wanted to use the RedHat box to help compile Gentoo. After several
false starts, I found that this works.
1. Copy entire Gentoo filesystem to a directory on the RedHat box.
tivopc> mkdir /work/tmp/distcc-root
tivopc> cd /work/tmp/distcc-root
tivopc> ssh -n [EMAIL PROTECTED] 'cd /; tar cf - . --exclude==./proc \
--exclude=/usr/portage/distfiles' | sudo tar xfp -
2. Mount /proc in the right place (needed so distccd can know
we have two CPUs).
tivopc> sudo mount -t proc proc proc
3. Chroot into the gentoo filesystem.
tivopc> sudo chroot .
4. Clear your environment (very important, and learned the hard way)
and become a non-root user. Note the kbob is not a known user
on tivopc, but he is on newbox.
tivopc# env - sudo -u kbob
5. Start distcc daemon.
bash-2.05b$ distccd --verbose --daemon \
--log-file=/home/kbob/distccd.log
6. Over on newbox, set it up to run 3 jobs each on localhost and tivopc.
Add some things to /etc/make.conf too. (I'm still not sure I have
the right stuff there, suggestions are welcome.)
newbox> sudo distcc-config --set-hosts 'localhost/3 tivopc/3'
make.conf:
FEATURES="distcc"
CC="distcc"
CXX="distcc g++"
MAKEOPTS="-j8"
7. Emerge big packages.
newbox> sudo emerge xfree kde emacs mozilla
Anyway, sometimes it uses both machines fully, and sometimes tivopc is
standing idle. I have gkrellm running on both. I *think* it's
working as expected.
