When not building one of the above distros, please use docker or some chroot.
This repo contains an example Ubuntu container.
$ cd docker
$ docker build --build-arg UID=$(id -u) -t yocto_builder .
$ docker run -it -v /path/to/yocto-rpi-example:/home/builder/yocto yocto_builder
container$ cd /home/builder/yocto/
Building
--------
Open init.sh and set MACHINE either to raspberrypi4-64 or raspberrypi3-64.
Other variants should work too, but are untested.
Source the init.sh script and use bitbake
$ . init.sh
$ bitbake its-image
The final image will be tmp/deploy/images/raspberrypi4-64/its-image-raspberrypi4-64.wic.bz2
You can flash it into you SDCard using dd. e.g
$ bzcat its-image-raspberrypi4-64.wic.bz2 | dd of=/dev/mmcblk0 bs=32M
