I cannot compile python-3.8.5 on on my Raspberry Pi 3 anymore because MAKEOPTS="-j1 -l1" is not applied for (all) build phases. At least the configure phase and some phases in the end use all CPUs here. In turn, this tears down the entire Rapsberry Pi due to RAM and/or temperature issues. This also happens on amd64, not only arm. Very similar or same issues: https://bugs.gentoo.org/715542 https://bugs.gentoo.org/716758 Thanks Reproducible: Always
Created attachment 655098 [details] build.log for amd64
Some info with a workaround patch is available in bug #720050. The problem is that compileall.py is called with -j0 option, so it uses all available threads.
Created attachment 655178 [details, diff] patch to remove -j0 Slightly modified patch as linked to in this comment: https://bugs.gentoo.org/720050#c16
Thanks for pointing to bug #720050. My patch (v2) is a slightly modified version since the original hat hunk errors. This helped partly: The final compile phase seemed indeed to run on one CPU core only, however, there is some intermediate phase where again all cores are used. These tests were run on amd64 and not arm yet so I believe my Raspberry Pi will not entirely be satisfied by this patch...

I suppose it would be better to sed it into correct job count. I'll look at it in a minute.
From a quick peek, the following parts do not respect MAKEOPTS: 1. setup.py build of extensions, 2. tests, 3. compileall. I'll try to patch all of them.

Fix confirmed at least for the -j1 case, on amd64 and arm (Raspberry Pi 3). @Michał: No patch but sed'ing in the ebuilds... quite a cool one. :-)
