Install fails on MacOS: `chrpath` not found about pymfem HOT 5 CLOSED

I think we should start moving towards libraries like scikit-build to help simplify some of the build logic.

Thank you @justinlaughlin for digging into this. I commented out the if statement and just set haveWheel=False, and tried to run

python setup.py install

In a fresh virtual environment with packages in requirements.txt, the above command installed mfem without any issues and examples run seamlessly. After installing mpi4py, I also succeeded to install its parallel version.

I also have the same problem as above. I have tried running both commands:

pip install mfem pip install mfem --no-binary mfem

from pymfem.

I can not reproduce this error on my Mac. My operating system is older (Monterey), but I am suspecting this may relating to the version of setuptools, since in my environment, it does not call chrpath. I used python -m pip install ./

from pymfem.

Okay, I did some digging into setup.py.

• chrpath is only run if do_bdist_wheel==True
• do_bdist_wheel==True only if configure_bdist() is run
• configure_bidst() is only run if haveWheel==True
• haveWheel==True only if from wheel.bdist_wheel import bdist_wheel on line 38 has no import error.

Thus, if wheel is installed and has bdist_wheel, setup.py will try to build a wheel, and will fail if chrpath is not installed.

Looking at the CI scripts:

• In testrelease_binary.yml wheel is installed but chrpath is also installed on line 73 via yum.
• In test_with_MFEM_*.yml, the installation for wheel is commented out.

@dohyun-cse and @andy9t7 can you try adding the flag haveWheel=False in setup.py after line 41 where it is set? I am guessing you are running into this error but @sshiraiwa is not because you already have wheel installed. This needs to be fixed and made more robust, but I don't believe building the wheel is necessary, so the easiest hot-fix for now is to just set the flag to False.
