We cannot use 'make -j' option to build the world, period.

[Makoto MATSUSHITA]

matusita I've found that current src/sys/modules/linux for RELENG_4
matusita is not 'make -j' safe. It maybe causes a problem if you want
matusita to make a module.

Long time has past and, but problem is still there.

OK, we all FreeBSD users should forget the fact that there is an
option '-j' in make(1) and it's helpful for building FreeBSD. I dunno
what it should be, but 'linux' modules breaks the existing situation.
Documentation team, you should delete some comments of this option in
cutting-edge/chapter.sgml.

Moreover, I've found that exactly the same problem is also in latest
5-current (I've tested with 'make -j 2'). Be careful that some
programs are called twice.

There is yet another compilation problem in kernel modules. A logfile
attached below comes from 'createBOOTMFS' stage of src/release/Makefile

rm -f .depend
mv -f .newdep .depend
cd ../../modules  env MAKEOBJDIRPREFIX=/usr/src/sys/compile/BOOTMFS/modules KMODIR=

Be careful, '3dfx' directory is called twice, and one of them doesn't
know that there is an obj/ directory. Maybe it is introduced by the
changes of cool and long-awaited feature of driver.conf.

AFAIK, we've never really supported -j for kernel building (which the
linux module is part of).  -j makes for world should certainly still
work.

Or you could help debug the problem and submit at Makefile patch. :-)

dcs Err, we have been supporting -j for kernel building for a LONG
dcs time. The "depend" and "install" targets did not support it, but
dcs support on the "all" target is about as old as support on the
dcs "buildworld" target.

AFAIK, that's right.

Obrien, please check src/release/Makeefile commitlog of revision
1.536.2.15 (for 4-stable) and 1.557 (for current) via CVSweb (or whatever):
http://www.freebsd.org/cgi/cvsweb.cgi/src/release/Makefile

You can see two make variable, WORLD_FLAGS and KERNEL_FLAGS, to pass
some options such as -jX to make(1) if you want to do make release.

obrien Or you could help debug the problem and submit at Makefile patch. :-)

Maybe that's great, but sorry I don't have a time to do now...

Yes, but it has worked fairly well with values up to -j 10 on the
machines I have access to at work :-)

I usually do a make -j 3 NO_MODULES=yes and then a separate make for
the modules.
