Not having great success building on pi4 (2GB) + raspi OS arm64 https://downloads.raspberrypi.org/raspios_arm64/images/raspios_arm64-2022-04-07/2022-04-04-raspios-bullseye-arm64.img.xz

Was following whats written here

lol I think its just /usr/lib/gcc/aarch64-linux-gnu/10/cc1plus maxing out the raspi4 unit (swap space)

I'll cross compile instead :-)

kbingham commented

Yes, parallel builds don't work on the RPi4 with lower memory - as it quickly exhausts all available RAM.

I've started : https://gist.github.com/kbingham/b35cc1402d02b0ef41b450941ad8f0c3 recently as a way I hope can simplify cross compiling for RPi - but it's a work in progress, I've compiled, but not yet worked out how to packaage/install the results into a device. Might help you though.

kbingham commented

If you try it, please let me know how you get on - and how we might improve it - then it could be incorporated into the project somehow perhaps…

kevleyski commented

Yeah that looks good (though I'm not using bullseye so my baseline docker is different, but similar)

kbingham commented

Also - you can try 'ninja -j1' to make sure you only do a single thread build on the RPi - it's really slow - but it might have a better chance of surviving a compile without exhausting the RAM.

My original simple docker gist has evolved a little into this, and I still hope to further get this into something that coudl be then later merged to libcamera itself too.
