Re: compiling with distcc on x86_64 from within a 32-bit chroot?

Thanks for the reply, Martin.  Here what I'm doing now that seems to be working, but it is rather complicated:

*I have 32-bit chroots on two x86_64 machines (paths mounted, just not chrooted into them).
*The distccd daemon is running on both x86_64 machines from the normal x86_64 root, and I need to stop it to make this work.
*I stop distccd on both machines (from normal x86_64 root)
*I start distccd inside the 32-bit chroot on both machines:
$ sudo chroot /bin/bash /opt/arch32
 (once inside I start the daemon then exit the chroot)

Finally, outside of the chroots, I am able to use the schroot command to start the 32-bit builds and it works with distccd!

$ schroot -p -- makepkg -src

(makepkg is a wrapper script for make on Arch Linux.)

Main question: is there an easier way, one that wouldn't involve the daemon stopping on the main environment (x86_64) and starting it up inside the chroots (i686) of both machines?

When I try it without those steps that I have outlined above, it does not work.

*I have 32-bit chroots on two x86_64 machines (paths mounted, just not chrooted into them).
*The distccd daemon is running on both x86_64 machines from the normal x86_64 root.

Note that if I run the makepkg wrapper script at this point, I will successfully compile in the x86_64 using distcc.

*Outside of the chroots, I run the build script from the schroot command:

$ schroot -p -- makepkg -src

It build fails in many errors when the script hits a make step.  In this case it is "make prepare" as I attempt to build a kernel.  All 252 lines of the resulting errors are on pastebin to keep this post as crisp as I can :)

Advice is appreciated!
