ARM support

[FrederikVanEeckeVintecc]

Hi,

I'm trying to pip install pysoem on my jetson orin nx, which is an ARM device. I'm using python3.8.10 and cython 0.29.34. The install fails both locally as within my docker container.

Any ideas what may be causing this error?

Kinds regards, Frederik

I would expect that this is related to the very recently updated Cython package. If you jump to the second last Cython version via pip install Cython==0.29.36, the pysoem install might work.

Hi, thanks for the response. Fixing the Cython version to 0.29.36 within the pyproject.toml file solved the problem.

I can confirm I got the same problem. Works just fine on amd64, but exactly same error on arm64/Jetson. Suggestion to pip install Cython==0.29.36 did not help in my case. Did not try to fix it in source in pyproject.toml though.

For now walkaround was downgrading to 1.0.8 of pysoem. However, it seems to not always work still, still fails in CI/arm64v8 docker, but passes natively on Jetson, which is weird, since on purpose both are using same distros (focal, python 3.8.10). I just kept wheel built on Jetson, but thats not a permanent/maintainable solution...

I tried to fix the compilation error caused by the new Cython version, and I hope the new pysoem version just uploaded PyPI works fine.

Thanks for incredibly fast support :) Confirmed working in docker arm64v8
