License file issue with awscrt???????

@jpeddicord @Kriechi @bretambrose @sfod

[xiazhvera]

The awsiotsdk package depends on the awscrt library. Based on the error, it looks like Python is unable to find a pre-built wheel for awscrt and is attempting to build it from source.

However, a wheel should be available for Linux ARM64 with Python 3.13. And I was able to install properly with ubuntu arm64 environment. You can find the wheel here:
https://pypi.org/project/awscrt/#awscrt-0.27.4-cp313-abi3-manylinux_2_17_aarch64.manylinux2014_aarch64.whl

I don't have a clue why Python 3.13 isn't picking up the correct wheel on your end so far. As a temporary workaround, you can try building awscrt from source:
awscrt GitHub repo: https://github.com/awslabs/aws-crt-python/
Prerequisites and build instructions:
https://github.com/aws/aws-iot-device-sdk-python-v2/blob/main/documents/PREREQUISITES.md

Here is my testing environment for reference:

> $ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.2 LTS
Release:        24.04
Codename:       noble
> $ uname -m
aarch64

I moved this over to awscrt since it is their failure

[xiazhvera]

While you build from source, you might encounter SetuptoolsDeprecationWarning: project.license as a TOML table is deprecated again. Try using 0.75 <= setuptools < 0.77 to avoid it.

[wills721]

Its not a warning -- its a failure. But, thank you I will try.

[wills721]

@xiazhvera If I try to install that whl I get:

(test) will@will-desktop-home:~$ python3 -m pip install awscrt-0.27.4-cp313-abi3-manylinux_2_17_aarch64.manylinux2014_aarch64.whl
ERROR: awscrt-0.27.4-cp313-abi3-manylinux_2_17_aarch64.manylinux2014_aarch64.whl is not a supported wheel on this platform.

[xiazhvera]

Looking more into your logs, you are using python3.13t which is not compatible with python3 abi3. And awscrt only provides wheels for abi3. You would need to build awscrt and awsiotsdk from source if you would like to use python3.13t. Also, don't forget to make sure setuptools is using version [0.75, 0.77).

To build from source, here is the steps

1. Install / setup prerequisites
   https://github.com/aws/aws-iot-device-sdk-python-v2/blob/main/documents/PREREQUISITES.md

2. Build a local awscrt library: https://github.com/awslabs/aws-crt-python/
   Please note the default local build version of awscrt is set to 1.0.0-dev, if you would like to use your local build, you would need make awsiotsdk to point to awscrt-1.0.0-dev by update the version value here:
   

   aws-iot-device-sdk-python-v2/setup.py

   Line 43 in 43c6cf6

   'awscrt==0.27.4',

3. Build awsiotsdk from source:
   https://github.com/aws/aws-iot-device-sdk-python-v2/?tab=readme-ov-file#install-from-source

[wills721]

@xiazhvera Yes, this is what I am trying to do. I want the OS threads available in 3.13. Ok, I will review this and build myself. Thank you.

[xiazhvera]

@wills721 Just a quick note, you want to avoid os.fork() if you would like to use the library with OS threads. Details at: https://github.com/awslabs/aws-crt-python/?tab=readme-ov-file#fork-and-multiprocessing

I'm gona close the ticket if there is no further questions.
