[gentoo-user] Cross-compiling

[Michael Sullivan]

I've read over the guide at
http://www.gentoo.org/doc/en/cross-compiling-distcc.xml about
cross-compiling with distcc.  This may be a really stupid question, but
how do I force my slow box to use cross-compiling via distcc?  Is there
some special option I have to pass to emerge to invoke it?  The guide
was not very clear on that point....

	Have a look at distcc-set-hosts and man distcc.

	Good luck. :-)

look here: http://www.gentoo.org/doc/en/distcc.xml
you just have to put "distcc" in FEATURES in make.conf...
and use distcc-config --set-hosts to specify the participating machines...
and of course start distccd in each partitipating pc...

make sure you put the other faster machines first in the host list.

but after all that, some ebuilds don't let you use distcc because it
seems to break them.  So don't expect it to work for everything.

Another option is to nfs-mount the client's hard drive on the fast
box,  bind a portage tree into the filesystem, chroot & proceed to
emerge.  

Or you could build the whole filesystem on the server, and push changes
out to the client with rsync or some such thing.  I don't know how to
use rsync for this, but I believe it's what it's for.
