Python 3.12.5

I understand the recommended system is Ubuntu, but vanilla AOSP (of any version) builds fine on Arch.

Seems to be an issue with compiling libcamera fork that is part of Raspberry Vanilla project but not part of AOSP.

Sorry, no clue with the issue itself. Compiles fine on Ubuntu 22.04 LTS which has Python 3.10.12.

Looks like some package incompatibility. I didn't manage to build it from arch directly, but created a docker builder instead:
