Orjson, requires a 64-bit Python with>3.8.5+and<3.9
Cannot be used on embedded devices such as routers and some ARM devices
You can remove this library and use Json directly?

[bdraco]

Json is too slow to meet iOS 16 requirements

orjson builds just fine on 32bit. Home assistant is using it.

[bdraco]

There are 32 bit wheels at:

https://pypi.org/project/orjson/#files
And musl ones here
https://wheels.home-assistant.io/musllinux/

Thank you for your reply. I have tried, but I am using Asus88u CPU with armhf architecture, which unfortunately does not support it. They only support armv7 and armv6

[bdraco]

armhf can mean different things depending on the os vendor. If its ARMv6 + musl you can use https://wheels.home-assistant.io/musllinux/orjson-3.8.10-cp311-cp311-musllinux_1_2_armv6l.whl

[fwebcc]

loog@RT-AC88U-2C70:/tmp/mnt/fwebcc/tmp# pip3 install orjson-3.8.10-cp311-cp311-musllinux_1_2_armv6l.whl
ERROR: orjson-3.8.10-cp311-cp311-musllinux_1_2_armv6l.whl is not a supported wheel on this platform.

[bdraco]

Are you using glibc?

[bdraco]

That wheel is for musl + python 3.11

[bdraco]

for python 3.10 https://wheels.home-assistant.io/musllinux/orjson-3.8.10-cp310-cp310-musllinux_1_2_armv6l.whl

[fwebcc]

Thank you. I'll try upgrading to Python 3.10 later now python3.9

[fwebcc]

libc-2.23.so

[bdraco]

You need glibc wheels. It doesn't look like anyone is already building thoose

You can fork orjson and add whatever qemu arch you want here
https://github.com/ijl/orjson/blob/c2514ab9ecdb9d42945f3fc6e18475b88bef8ec2/.github/workflows/linux.yaml#L213

And than use github actions to build them or send them a PR

[fwebcc]

https://wheels.home-assistant.io/alpine-3.14/armhf/HAP_python-4.4.0-py3-none-any.whl
It can run

[bdraco]

I opened a test PR to see if armv6 can be built that way as well
bdraco/orjson#1
It will take a few hours to get a result

Hi there, first of all thanks a lot for this amazing library, I am truly awed on what you have accomplished here. Also, apologies if my error is not related to this issue but it seemed to me after quite a bit of googling that it might be a 32/64 bit issue as well.

I am trying to use this on a Raspberry Pi Zero W (ver 1.3) with Raspberry Pi OS Lite (32bit) port of Debian Bookworm with no desktop environment installed - It is worth mentioning everything works fine on my Raspberry Pi 3 with a 64bit OS.

After failing on my first go, I managed to install all the requirements one by one without issues on my venv, orjson required me to install rust manually but that did the trick.

`(PythonHAP) rik@PiZeroIRHat:~/.hap-python $ pip list
Package Version

---

async-timeout 5.0.1
base36 0.1.1
cffi 1.17.1
chacha20poly1305-reuseable 0.13.2
cryptography 44.0.0
h11 0.14.0
HAP-python 4.9.2
ifaddr 0.2.0
orjson 3.10.14
pip 23.0.1
pycparser 2.22
PyQRCode 1.2.1
setuptools 66.1.1
zeroconf 0.137.2`

The issue however persists when running my python script, it fails importing the AccessoryDriver due to what seems to be a Cryptography error :

(PythonHAP) rik@PiZeroIRHat:~/.hap-python $ python hap-python.py Traceback (most recent call last): File "/home/rik/.hap-python/hap-python.py", line 8, in <module> from pyhap.accessory_driver import AccessoryDriver File "/home/rik/PythonHAP/lib/python3.11/site-packages/pyhap/accessory_driver.py", line 52, in <module> from pyhap.encoder import AccessoryEncoder File "/home/rik/PythonHAP/lib/python3.11/site-packages/pyhap/encoder.py", line 9, in <module> from cryptography.hazmat.primitives import serialization File "/home/rik/PythonHAP/lib/python3.11/site-packages/cryptography/hazmat/primitives/serialization/__init__.py", line 7, in <module> from cryptography.hazmat.primitives._serialization import ( File "/home/rik/PythonHAP/lib/python3.11/site-packages/cryptography/hazmat/primitives/_serialization.py", line 10, in <module> from cryptography.hazmat.primitives.hashes import HashAlgorithm File "/home/rik/PythonHAP/lib/python3.11/site-packages/cryptography/hazmat/primitives/hashes.py", line 9, in <module> from cryptography.hazmat.bindings._rust import openssl as rust_openssl ImportError: libssl.so.1.1: cannot open shared object file: No such file or directory

Is this a 32 bit issue? if so, is there a way I could fix it myself locally compiling cryptography? I did read somewhere the piwheels were wrong, however they also said they fixed that on version 44.0.0... which left me clueless.

Thanks again for all your help and incredible work!!

Home Assistant ships 32bit crypto wheels so it's likely a problem with piwheels or a missing OpenSSL lib
