Python 3.10 tests currently failing

[JSKenyon]

Describe the bug Tests fail on Python 3.10 due to a binary incompatibility between the numpy version required by numba (currently < 1.23) and the numpy version used to build python-casacore. This cannot be resolved without a version of python-casacore which works with numpy < 1.23 or a version of numba which supports numpy>=1.23. Waiting for a numba release is the simpler approach but way take a few months.

To Reproduce Simply run the tests under Python 3.10.

Expected behavior QuartiCal should work under Python 3.10.

Use --no-binary ':python-casacore:' to force casacore to build against an older version of numpy. You'd need casacore on the system though.

Running:

pip install --no-binary "python-casacore" python-casacore

gives:

/usr/bin/ld: cannot find -lboost_python-py310-mt

Presumably this is a a libboost dependency but I am not sure what to install to satisfy it @bennahugo.

[bennahugo]

Yea you will probably need a reasonably new boost installed on the system

This is on 20.04. I still think I am justified in whining as this basically renders QuartiCal uninstallable under Python 3.10 without fiddling. I suspect that 20.04 doesn't have a sufficiently recent boost and installing that manually doesn't really resolve the issue. I have opened https://github.com/casacore/python-casacore/issues/235 as I believe that there should either be a final python-casacore 3.4 release which supports Python 3.10 or the python-casacore 3.5 release should work with the first version of numpy to support Python 3.10 (Numpy version 1.22.0).

[JSKenyon]

This has been fixed upstream.

[bennahugo]

Yup agreed.

Boost is only bundled for the python that is natively bundled with your version - here 3.8 in other words.

It may help to upgrade to Ubuntu 22.04 which ships 3.10 as the default
