Description Toralf Förster gentoo-dev

Upstreams has the opinion, that the ebuild should configure it :

Are they right ?

This comment summarizes the upstream link.

Toralf reports a problem:

> I configured "make -j5" at my stable Gentoo, but the process lists shows, that each of 2 perl jobs runs 5 make jobs.

Upstream explains configure options:

> Our old (recursive) build system uses two configure options to determine how many jobs can be run:
> * --with-num-cpus tells how many directories can be build at once (one dmake process for each of them)
> * --with-max-jobs tells how many jobs each dmake can run

Upstreams addresses the ebuild maintainer:

> It is the ebuild's task to supply appropriate values for the options based on system-specific settings (e.g., MAKEFLAGS=-j5).

I closed this bug multiple times already.

It will be causing this issue until 4.0 release (3.7) where we addressed it correctly.

If i would set the -jobs to 1 then half of your build would not be paralel in older releases at all.
