Same issue on M1 MacOS, Python 3.10. I ran poetry add ecos, and it fails with:

Any ideas on how to fix that?

Installing 2.0.5 version worked for me in Mac M1 processor. Looks to be some issue with the latest version.
pip install ecos==2.0.5

[jacopofar]

@thirumalairajr could you share on which Python version you are? I'm trying to help a colleague with M1 but cannot get this to work with Python 3.9 nor building it

[baslia]

Hey, I have the same issue with M1 mac and python 3.9

[thirumalairajr]

@thirumalairajr could you share on which Python version you are? I'm trying to help a colleague with M1 but cannot get this to work with Python 3.9 nor building it

I am using Python 3.11.2

Same problem here!! M4 Pro

Ecos version 2.0.14 installs and runs fine on my M1 and M2 for Brew installed Python 3.13.2 on Mac OS 15.3.1. Installed by pip3.
