Install fails because uamqp wheel build fails

[waku1123]

I want to install azure-iot-hub in a virtual environment (pip install azure-iot-hub), but the build of uamqp wheel fails.
Is there something wrong with the installation method?

M2 Pro
MacOS 14.4.1
python 3.9.17

azure-iot-hub depends on azure-uamqp-python package which is deprecated and fails to build on certain systems including Mac ARM and Linux ARM on Python 3.12+.

As a stopgap, I developed an small alternative package azure-iot-hub-api that has basic functionalities to use in my own project until the azure-iot-hub receive necessary updates. I tired to keep it as similar as possible to azure-iot-hub.

Also, there exits another package azure-iot-sdk-python which I haven't used, maybe it helps.

How is there still no official solution? @cartertinney , is this SDK discontinued?

[sugawarayss]

it looks like this package is not maintained...

I took advantage of this package’s functionality by ignoring build errors. Because only some features were needed.

CFLAGS="-Wno-error=incompatible-function-pointer-types" pip install azure-iot-hub

[timozerrer]

Thank you @sugawarayss . Are you aware which features are affected?

[sugawarayss]

@timozerrer
I don’t know if this is correct, but I think it probably affects the part where C2D messages are sent. However, I was able to send C2D messages even if I ignored the build error on my device local.

[timozerrer]

This workaround does not seem to work on Python 3.12: Azure/azure-uamqp-python#386 (comment)
I can confirm build is still not running using Python 3.12 and M3

[sugawarayss]

fmmm...
i use Python 3.9.17 on M2 MacOS device...

Is there any official update on this issue. This is really big gap for anyone using Mac as a development machine. Python SDKs are supposed to be fully cross platform.
