Building error: Already planning to copy library with same basename as: libstdc++.6.dylib

[MartinPdeS]

Hello, I would like to report this problem I am having. I am trying to build my code (python api wrapping c++ and fortran core) and I am facing this error message (at the end of message) that doesn't help me at all. I have been reading through a lot of documentation and forums but couldn't find anything to help. My workflow file is pretty simple:

================================================================

While it may not be a bug but an error from my side, I think the error message is not clear.

I am new at using delocate, so I don't really know what is the expected behavior, but with auditwheel i would expect delocate to produce my repaired wheel file.

Here is the link for the github workflow https://github.com/MartinPdeS/PyMieSim/actions/runs/3348332811/jobs/5547283200

Many thanks
