Can't build nlopt wheels

[devin-saini]

I am trying to install nlopt from the command line using "pip3 install nlopt" on macOS but am getting the error "ERROR: Failed building wheel for nlopt
ERROR: Could not build wheels for nlopt, which is required to install pyproject.toml-based projects"
I have tried trouble shooting on my own but still can't resolve the issue.

I'm also having trouble installing on Mac M1. There seem to be no arm64 builds on PyPI so it looks like only Intel Macs are supported. Please could you build for arm64 and include it in the artefacts you upload on release?

Here's my error (I'm using poetry which uses pip under the hood):

@DanielBok I can see you've made a couple of releases for the latest version of nlopt for different versions of python. Would it be ok to update your workflow to include using GitHub's Mac M1 runner to build and publish an arm64 wheel? I think it would just be a case of adding the macos-14 runner to this line

[cortadocodes]

@DanielBok I've made a pull request here - would you be able to allow the build workflow to run to test if it builds ok for M1?

I have a similar Problem on an M3 Mac.

Reproduction

To isolate the problem I created a conda environment that just contains Python and then pip-installed nlopt into it:

conda create -n testenv python=3.10 -y
conda activate testenv 
pip install nlopt
