Parallel build of packages
HI all!
Is it possible to make pkgsrc use more than 1 CPU for building packages (make -jX) ??
I have installed NetBSD 2.0 with SMP kernel on my dual sparcstation 20 and it would be nice to speed up the builds.
regards
DD

Re: Parallel build of packages
Issue the command 'top' as you build a package.
Isn't both processors under load without passing
any extra flags to make?

Oh, I forgot a small detail, make is single threaded and therefore do not
take advantage of several processors unless parallell make processes are
launched.
You can put CFLAGS+=-j2 in /etc/mk.conf. Make understands when two
build processes do not depend on each other and parallell builds can be
launched.

Doesn´t seem to work.
CFLAGS+= sets extra flags to pass to the compiler, not to make.
Any other ideas ? It would be really nice to get both 50 Mhz working

Re: Parallel build of packages
ops, try MAKEFLAGS instead.

Thanks, that did the trick.
