Unable to install from formula

[ritesh]

I'm trying to install openEMS on mac using the instructions on the wiki for macOS (version 14.6.1, Sonoma).

brew tap thliebig/openems https://github.com/thliebig/openEMS-Project.git
brew install --HEAD openems

This fails firstly due to a mismatch in the version of hdf5. I tried to hack around this by changing the homebrew formula to depend on hdf5@1.10 (line 19). I'm a newbie, so I don't know if this will break other things!

depends_on "hdf5@1.10"

This seems to fix the compilation issues, but it fails to install the python dependencies - here I'm not sure how to proceed.

Has anyone had success in installing on macOS recently?

Hi. Try pip install setuptools and run it again. You may try this PR as well.
