Hi Maxence,<BR>
<BR>
Have you looked at distcc? Its probably closest to what you're<BR>
requesting:<BR>

I help out with Fedora Extras so I can certainly appreciate the time<BR>
that goes into compiling packages! It would be nice to have a<BR>
distributed build system with per-compilation-unit (eg. per-object-<BR>
file) granularity. But I'm afraid it may be a somewhat complicated<BR>
task for, for instance, Fedora Extras since the FE build system uses<BR>
a chroot-ed environment (the "mock" package) to ensure build<BR>
cleanliness and the presence of all the needed dependencies. Maybe<BR>
NFS-mounting the chroot would be sufficient...?<BR>
<BR>
If you split up the work on a per-package and per-architecture basis<BR>
(i386, x86-64, ppc, etc.) then its relatively (!) straight-forward to<BR>
build a cluster with the necessary hardware and perform builds of<BR>
separate packages/arches on a simultaneous (each in different chroots<BR>
on potentially different machines) basis. Thats exactly what the<BR>
current Fedora Extras build system (called "plague") does. You can<BR>
see some details at:<BR>

<A HREF="http://fedoraproject.org/wiki/Extras/BuildSystemClientSetup">http://fedoraproject.org/wiki/Extras/BuildSystemClientSetup</A><BR>
<BR>
And I only discuss Fedora Extras because its what I'm familiar with.<BR>
I'd be curious to hear how build systems work for other distros!<BR>
