Pre-built wheels for Linux on ARM?

[sindre-nistad]

Would it be possible to distribute pre-built wheels for linux-aarch64 on PyPi?

My use-case is using JPype1 (through JayDeBeApi) on a docker container running on Apple Silicon.
Currently, we compile JPype1 from source while building the container, which takes a little while in addition to installing the necessary compiler and libraries.

On a slight side-note; thank you very much for this library 😊
It has / is very useful when I have to interact with some vendor-provided Java programs / libraries.

We use the .azure scripts to build all the architectures that we currently distribute. Assuming you can find a recipe to create such a build using the Microsoft Azure cloud, I can add it to the distribution. I would guess that adding another OSX job as found in release.yml (line 144) with a different image/python.architecture file should produce the additional images. We also had a pattern for producing docker based distributions in the past though that was with a previous cloud. I am not sure if we have been successful on azure.

If you want to work on that I believe that you just need to fork the repo, open a azure cloud account, then trigger the release pipeline on your fork. Unfortunately, due to other time commitments I can't work on this myself, but would be happy to accept a contribution if others can work out the pattern. It has been an ongoing problem in which either the Python arch or the Java arch fail to match. I know it is possible to build and run assuming both are matching and thus we can distribute it.

Here is what limited research that I found relevant to the topic:

I have previous found lists of the available vmImages. We are using osx-11 which as far as I am aware is a x64 image.

It appears that there should be a pool of machines for arm64 released in 2023, though I am not sure how to specify the target.

Azure/azure-dev#1314

There are some posts indicating that as of a year ago Python compilations against arm64 did not work on Azure. But I haven't the time to follow through to see if that condition has changed. This would need to be resolved before a successful build is possible.

Thanks,
I'll look into it. I have experience working with Azure

#910 something seems to be broken.

@sindre-nistad did you have the chance to take a look and point us toward a solution? Thanks

Unfortunately, I haven't :(
Though, hopefully I will have time to look at it in the near future

I think we have it almost solved in #1234

The aarch64 users should be happy now with version 1.5.1. Please check it out.
