[SOLVED] Cannot compile with buildroot 2022.08.1

Issue

I'm having issues compiling with buildroot 2022.08.1. There seems to be nothing on the internet (that I can find anyway) that can help me so I'm turning to the legends of the internet.

Currently on linux mint 20.3, Kernel 5.19-surface

Normally I wouldn't ask but I can't really find much of a specific error message here that I can understand. I have compiled with buildroot on this computer before with just the default defconfig for the raspberry pi 3 but obviously having more configuration on that profile has opened it up to issues.

The build nearly finishes and then does the following:

Thought it may have been something to do with not enough storage allocated for the .img file (originally 300M because it's a very bare bones raspi3 image with only bash, graphics utilities and python), but i've added a bit more(an extra 200M) and it still has the same issue.

Help appreciated.

Solution

aarch64-buildroot-linux-gnu-g++.br_real: fatal error: Killed signal terminated program cc1plus

This is a typical symptom of an OOM (Out-Of-Memory) - the v8 javascript engine takes a lot of memory. Check the kernel logs on your build machine (journalctl -ke or dmesg | less) just after this error happens.

If it is indeed an OOM, it is sometimes possible to work around it by reducing parallelism. You can do this by setting BR2_JLEVEL to a lower value in the Buildroot configuration.
