M1 ARM is not supported yet. We can build for ARM64 Linux already, but we don't have any machines or CI with M1 support, AFAICT.

PMeira commented 2 years ago

I just adjusted the build scripts for DSS C-API to include aarch64 on macOS in the next release PR at https://github.com/dss-extensions/dss_capi/pull/109

I imagine building the Python wheel won't be much harder, but still there is the lack of testing. We could release it anyway and just add a warning to the release notes, but people rarely read those.

I added a cross-compiled wheel:

(EDIT: updated)

pip install dss-python==0.12.0b5

Untested, but should work.

PMeira commented 2 years ago

The build steps are now integrated in the workflow for GitHub Actions, so wheels for macOS ARM64 are prepared with the rest.

Hi @PMeira, thanks for working on the M1 architecture. I just tested with macOS 12.0.1 on M1 w/ Python 3.9.10 virtualenv, but received an ImportError:

pip install dss-python==0.12.0b3

@charraig Thanks for testing it! Please retry with pip install dss-python==0.12.0b4. A compiler flag was missing in the previous one, so the output libs resulted in mixed architectures.

@PMeira Thanks! I tested the new version and it worked perfectly.
