[gentoo-user] Specific MAKEOPTS for one package

Hi Folks,

I have set MAKEOPTS="-j3" in my make.conf. That is great for most
packages but when I compile firefox that makes my box exploding as it
consumes simply to much RAM.

Is there an option to set -j1 just for firefox package? (and rust, that
has the same problem)?

Regards
   Klaus

I think you are looking for this:

https://wiki.gentoo.org/wiki//etc/portage/package.env

It's been a while since I've had to do this but I'm fairly sure that
will do what you want. 

Hope that helps.

As Dale and Michael said, but you may find -j2 acceptable; It's what I use for 
everything here.

Thanks Dale and Michael, that was exactly I was searching for. (I think.

No. Firefox and Rust is such a beast. It kills my machine even with -j2.

Memory may be your issue. A wide variety of places to look at::
ebuild
kernel
userland


I'd suggest you start with reading up on 'jemalloc' as a place to start.
Hopefully other will 'chime in' on debugging/controlling memory
constrained systems and large memory requirements on older/limited
resources.

hth,
James

  I assume you have 2 cores on your cpu and you're adding 1 as per the
ancient rule.  That may not be the best option anyways.  See
https://blogs.gentoo.org/ago/2013/01/14/makeopts-jcore-1-is-not-the-best-optimization/
The author of the blog post ran multiple tests, and concluded that
setting MAKEOPTS -j to the actual number of cores is slightly faster.
Years ago, the gcc compiler was less efficient, and adding 1 to -j did
improve compilation speed.  That is apparently not the case today.

True.

Interesting thoughts.

First, cpufreq-set seems to be not available on gentoo anymore. Doesn't
matter, just giving it a try.

It came out, that all build times have nearly the same sys times but the
user and real times vary. Funny, this is a two CPU machine but the build
with -j1 consumes the least user time. Just the real value gives the
same pattern than on the site.

You want sys-power/cpupower these days.

  I wrote up a bash script (Yes!) to do cpu speed control.  As a script,
it has no external dependancies.  The only requirements are that the CPU
supports frequency scaling, and that the appropriate CPU governors are
compiled into the kernel.
