Python Bindings fails on Mac M2 #241

Open pkeshava opened 1 month ago

pkeshava commented 1 month ago

I've successfully used brew to install openems and have verified that AppCSXCAD runs. However, I cannot get the python bindings to install. I've tried many things including the recommended steps in the documentation along with the discussion in #190 with no luck. The main issue is that the linker cannot find the CSXCAD lib, i.e., regardless of whatever method I try, I eventually get the error:

ld: library 'CSXCAD' not found clang++: error: linker command failed with exit code 1 (use -v to see invocation) error: command '/usr/bin/clang++' failed with exit code 1

after I've run

/opt/homebrew/opt/python@3.13/bin/pip3 install python/. --break-system-packages --user

I suppose I have to use LDFLAGS=...? but I'm not sure of the path to the lib?? This error occurs regardless of whether I use a virtual env python or the system wide as shown above

May want to try #239 ? I was having several issues installing the Python modules on Linux, with that now it works like a charm.

That seems to have done the trick. Thank you!!

Did Homebrew successfully install the python packages to its managed version of python? You shouldn't have to install it separately.

Try running /opt/homebrew/bin/python3 and see if import openEMS works. To make a python environment you can install further packages into, I would create a venv from that version of python with the --system-site-packages option. This way, everything gets upgraded at the same time when you upgrade via Homebrew.
