Hi Maxence,

Have you looked at distcc?  Its probably closest to what you're


I help out with Fedora Extras so I can certainly appreciate the time
that goes into compiling packages!  It would be nice to have a
distributed build system with per-compilation-unit (eg. per-object-
file) granularity.  But I'm afraid it may be a somewhat complicated
task for, for instance, Fedora Extras since the FE build system uses
a chroot-ed environment (the "mock" package) to ensure build
cleanliness and the presence of all the needed dependencies.  Maybe
NFS-mounting the chroot would be sufficient...?

If you split up the work on a per-package and per-architecture basis
(i386, x86-64, ppc, etc.) then its relatively (!) straight-forward to
build a cluster with the necessary hardware and perform builds of
separate packages/arches on a simultaneous (each in different chroots
on potentially different machines) basis.  Thats exactly what the
current Fedora Extras build system (called "plague") does.  You can
see some details at:


And I only discuss Fedora Extras because its what I'm familiar with.
I'd be curious to hear how build systems work for other distros!
