Is orjson supported on 32-bit Raspberian?

[timchurches]

Even after installing rust, cargo etc, orjson fails to build on a freshly-installed 32-bit Raspberian OS on an RPi Zero W. The rustc compiler runs, but never finishes (at least not in under 24 hours, I gave up after that). V4.4.0 of HAP-python installs fine.

It should build. There are wheels provided by orjson and wheels from wheels.home-assistant.io that might work as well

According to this post orjson will not work with 32-bit python on a 32-bit linux OS: https://medium.com/geekculture/python-orjson-cb046b47ab8c

If that is true, it means the current version of HAP-python can't be deployed on Raspberry Pi 2 or Pi Zero W hardware, of which there are a lot still in use. It should work using 64-bit Raspberry Pi OS on Pi 3 or 4 or Pi Zero 2 (I'll test that when my Pi Zero 2 arrives).

Would it be possible to substitute UltraJSON (json - see https://pypi.org/project/ujson/ ) for 32-bit deployment of HAP-python? ujson supports 32-bit builds, and although not as fast as orjson, it is still many, many times faster than the standard json in python, and faster than most other fast json libraries (with the exception of orjson).

There did used to be a problem with 32bit but Home assistant has 1000+ of deployments with it on 32bit Linux so I think that link is outdated.

orjson has been adding additional wheel builds lately, so they might accept a PR to add your arch to their build CI

ijl/orjson@3de9685

32 bit support was added via ijl/orjson#220

There is an issue that might help you build wheels on github instead ijl/orjson#278
