OSError: [Errno 12] Cannot allocate memory

What's the recommended course of action here?

Log attached.

Suggestion:
1) ensure you only have 1 job running and absolutely no parallel builds. "=
=2D-jobs 1" for both emerge and make

2) get SWAP, preferably on USB stick/harddrive so as not to kill the SD ca=
rd.

Because rasppis are low on memory and they have very specific uses, I tend=
 not to bother with Gentoo on them.

Joost

I started getting a harddisk ready for a swap area, but then decided to try to emerge @system as a first step (using the -j 1 option this time - thank you) and that completed, as did then the subsequent emerge of @world.

It completed successfully (as I interpret it) with only 1 package being emerged, but it also output these messages:

=C2=A0 Unclear to me is:

  • =C2=A0 why the non-matching USE flags didn't cause, this time, t= he emerge to break
