Dockerfile: ARM/aarch64 support for Raspberry Pi

[MatthiasLohr]

Hi,

do you see a chance to add arm/aarch64 support to the image? Currently, the image cannot be executed on a Raspberry Pi, but it would be really nice if that could be supported.

I would also offer my help to create such an image, if needed.

Best regards
Matthias

Hi @MatthiasLohr ,

If this can help you: I also had an issue (#369) running maturin to produce aarch64 wheels, but using a manylinux2014_aarch64 image on a MacOS platform.
As a workaround, I created a Docker image based on manylinux2014_aarch64 and including a compiled version of maturin 0.8.3: https://hub.docker.com/repository/docker/adlinktech/manylinux2014-aarch64-rust-nightly
See its Dockerfile.
We will now use it to produce aarch64 wheels for our zenoh-python project.

Hi @JEnoch,

thank you for your message, but unfortunately that does not help. The docker image which is created out of this project is used in a toolchain (where I'm just a user, not developer), which fails on Raspberry Pis when trying to build the project, since there is no Docker image provided for Raspberry Pis. And generally speaking, yes, I have solution how to work around this, but in my opinion it would be better if the toolchain is portable.

@MatthiasLohr maturin now has manylinux2014_aarch64 and manylinux2014_armv7l binary wheels uploaded to PyPi, does it help with Raspberry Pi?

For anything more complex than basic x86 compilation, I recommend running the appropriate manylinux docker container and installing rust and maturin during the workflow, as shown in https://github.com/konstin/complex-manylinux-maturin-docker

Shameless plug: for anyone who wants to cross compile to aarch64/armv7l, my manylinux2014-cross-arm docker images can be used.
