Not sure how I could make a pkgbuild…
The install.sh file assumes you are using a Debian/Ubuntu based distro, so it won’t work out of the box.
But you could probably change the apt-get line to match a pacman line that installs the needed dependencies.
The program may not work under Manjaro – some Ubuntu/Debian specific is hardcoded. But it’s only my suppose, I don’t have rpi to verify it.
I filed a bug report for no aarch64 support. Not holding my breath expecting a pkgbuildbut who knows?
That’s not issue with aarch64 platform but with support only for Raspberry Pi OS, Ubuntu ARM and other systems with apt package manager.
I looked at that install script. It has a nasty
sudo pip command.
Potato, tomato. Maybe they offer something…who can say
