Python Wheel for ARM (Raspberry Pi) processor

[mishas]

Looking at the pypi page for the project, there are many precompiled python wheels for different systems, but none for ARM (Raspberry Pi).

I'm working on a project with many Raspberry Pis involved, and it seems like running pip3 install pynacl takes ~20 minutes (!!!).

Interestingly enough, trying to compile it under emulation (qemu) it took even longer (~25 minutes).

It seems like Bug #302 helps a little bit, but not enough :(

Would it be possible to have a prebuilt Python Wheel for ARM as well?

Thanks.

We don't have access to any ARM servers, so I don't think is going to be possible.

Would you consider cross compiling that via Docker?

Here's a simple Dockerfile that would work:

FROM resin/armv7hf-debian

RUN apt-get update \
 && apt-get install -y python3-dev python3-pip libffi-dev build-essential \
 && pip3 install wheel

WORKDIR /root/

CMD ["python3", "./setup.py", "bdist_wheel"]

Put this file in the root directory of the project and run:

> docker build -t pynacl_builder .
> docker run --rm -v `pwd`:/root/ pynacl_builder

Thanks again!

We couldn't supply ARM based packages even if we wanted to because PyPI only allows uploading of specific "known safe" wheel types. Linux ARM wheels are not among that list (in fact, for linux only manylinux1 is allowed). If you wanted that to change you'd need to engage with the PyPA to begin creating an ARM manylinux spec.
