[petsc-dev] PETSc-3.16.3 and Python-3.11

[Lisandro Dalcin]

Dear Antonio,

It is hard for us to do that, sorry. The problem is not petsc4py itself,
but Cython-generated code.

The first thing you need is to install in-development Cython (as long as it
already supports Py 3.11, I have not checked).
Then you can use petsc4py from a git checkout, although that may be a bit
inconvenient to implement in your build script.
Alternatively, you can keep using the latest release tarball, but then in
your build script run `rm src/petsc4py.PETSc.c`, that will force Cython to
run again.
Another way to force C sources regeneration could be `python setup.py
build_src --force`.

I hope that helps,
