Failure to build on fresh ArchLinux

[appetrosyan]

Given that the AUR package has a missing MPI dependency I tried installing PolyChord in a fresh venv today. I don't think this has been reported yet, so odds are I'll close this issue myself, but leave it in, so if anyone later comes across it, they know how to fix it.

Here's the output of the build commmand:

× Building wheel for pypolychord (pyproject.toml) did not run successfully. │ exit code: 1 ╰─> [73 lines of output] running bdist_wheel running build running build_py make -C /tmp/pip-req-build-h_v66dsl/src/polychord /tmp/pip-req-build-h_v66dsl/lib/libchord.so make[1]: Entering directory '/tmp/pip-req-build-h_v66dsl/src/polychord' mpifort -ffree-line-length-none -cpp -fPIC -fno-stack-arrays -fallow-argument-mismatch -Ofast -DMPI -c utils.F90 [antares:111791] Error: Unable to get the user home directory [antares:111791] Error: Unable to get the user home directory -------------------------------------------------------------------------- It looks like opal_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during opal_init; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer):

note: This error originates from a subprocess, and is likely not a problem with pip.
ERROR: Failed building wheel for pypolychord
Failed to build pypolychord

This is running on a fresh pip virtual environment on an up to date version of Arch Linux with the pypolychord AUR package installed (i.e. it can be built).

This is the same result as if I run

pip install git+https://github.com/PolyChord/PolyChordLite@master --break-system-packages

Outside the venv.

It doesn't fail if you clone, and install via

sudo python setup.py install
