Build failure on Raspbian stretch

[klaashofman]

Describe the bug

Hi,

It looks like master build (8ed9c9d) fails on Raspbian stretch:

All dependencies are there, CMake is version 3.7.2

Full Log:

python3 -m pip install ./aws-iot-device-sdk-python-v2

    Uninstalling awscrt-0.13.5:
      Successfully uninstalled awscrt-0.13.5
  DEPRECATION: awscrt is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

It looks like you are running into a problem when installing the awscrt dependency. Can you try installing that by itself with:

python3 -m pip install awscrt

[github-actions]

Greetings! It looks like this issue hasn’t been active in longer than a week. We encourage you to check if this is still an issue in the latest release. Because it has been longer than a week since the last update on this, and in the absence of more information, we will be closing this issue soon. If you find that this is still a problem, please feel free to provide a comment or add an upvote to prevent automatic closure, or if the issue is already closed, please feel free to open a new one.

Same problem when installing awscrt first:
python3 -m pip install awscrt

Hi @klaashofman,

IoT Device SDK(Python) has a dependency on library awscrt. After looking into the RaspberryPI python distribution, I don't think awscrt for python3.8 is available there ( https://www.piwheels.org/simple/awscrt/ ). Also, support for RaspberryPi Stretch is not guaranteed by the piwheels. (Checkout https://www.piwheels.org/)

There is two possible workarounds you can try out:

1. Use python3.7 or python3.9 instead of python3.8
2. Installing awscrt from source instead of pip. You can find installation instructions from https://github.com/awslabs/aws-crt-python. Then please make sure IoT Device SDK uses the local awscrt installation before building it.

Let me know if the workaround helps.
