Yeah, seems to be an issue with MAGICC's Fortran libraries on macOS:

dyld: Library not loaded: /usr/local/opt/gcc/lib/gcc/11/libgfortran.5.dylib

Maybe there is a mismatch of required libraries for the compiled downloaded version and what's available on the CI images.

I fixed this in #79. The mac ci image changed and the gfortran dylib was moved/not exposed in the same way.

I'm not an expert with making Mac binarys that work anywhere so there might have been something we could fix at compile time

[rgieseke]

Thanks @lewisjared!
I've merged #79 so after merging the main branch and fixing the conflicts this should hopefully work, @maritsandstad

[maritsandstad]

Thank you @lewisjared and @rgieseke!

Things seem to all go green now;-)

LGTM! Merge if you're happy @maritsandstad

As long as nothing explodes, this should be released as part of v0.11.0 https://github.com/openscm/openscm-runner/actions/runs/2881581512
