I tried your patch by creating a v= ariant of the guix package=2E My first attempt was a failure because it's s= till using almost all my memory and I forgot to enable my swap=2E In the se= cond attempt, the build phase succeeded, but the build failed during the te= st phase (test/inferior)=2E I've started a new build hoping it's a non-dete= rministic failure=2E

Hi,

Julien Lepiller <julien@lepiller=2Eeu&=
gt; skribis:

 I tri=
ed updating my system on my armhf board (2GB of RAM), but during
 "guix =
system reconfigure", guix tries to build itself (the guix package
 from =
(gnu packages package-management))=2E This package uses too much
 memory=
 to build, and I start getting GC warnings like so:

 GC Warning: Out=
 of memory - trying to allocate requested amount (552
 bytes)=2E=2E=2E GC Warning: Header allocation failed: dropping block
 GC Warning: Out=
 of Memory! Heap size: 2571 MiB=2E Returning NULL!
 Warning: Unwind-only=
 out of memory exception; skipping pre-unwind
 handler=2E

 after =
some more progress and a lot more warnings, the build stops (CPU
 is at =
2%), but the memory is not freed=2E The build stayed stuck for a
 long t=
ime until I decided to cancel it=2E

This is ridiculous=
=2E  :-/

Can we ins=
tead break the build (at the Makefile level) into multiple
smaller chunk=
s, that require less memory, in the same way (guix self)
works?

Yes, that=E2=80=99s a good idea=2E

Could you check the e=
xtent to which the attached patch helps on this
machine?

It doesn=
=E2=80=99t split as much as (guix self) does, only in three pieces, but
=
hopefully that helps a bit=2E  A side effect is that progress report is
=
now off, but we can fix it later=2E

Thanks,
Ludo=E2=80=99=2E
