Petsc & slepc4py problem

[Jcini]

Hi, I'm using homebrew Python 3.10.9 on M1 macOS 12.6. Previously I had problem install firedrake on Mac, and made a post #2753. By setting MACOSX_DEPOLYMENT_TARGET, I was able to install and run pytest code, and I also run the code from "A basic Helmholtz equation" from firedrake website.

However, I think my Petsc and slep4py was not fully/successfully installed. When I tried to run the following lines:

from firedrake import *
from firedrake.petsc import PETSc
from slepc4py import SLEPc

It says there is no module called slepc4py.

I tried the following ways:

1. I tried pip install slepc4py. It has this error (I copied from terminal): install_slepc4py.txt. It seems partially installed something, but now I got error when I run from firedrake import *.
2. I tried update firedrake, but error occurs, here is the log: firedrake-update.log. I also tried the following but I still cannot update.

cd src/firedrake
git pull
./scripts/firedrake-install --rebuild-script

3. I tried firedrake-update --remove-build-files, and here is the error (I copied from terminal): firedrake-remove-build-files.txt.

Thank you!

The right way to have Firedrake with slepc support is to pass --slepc to firedrake-install or firedrake-update. pip install slepc4py won't by itself work. However, the subsequent steps you took will possibly have messed up your Firedrake install. I suggest you start with a clean install and pass --slepc to firedrake-install. If your install does not run cleanly then post firedrake-install.log and, if the failure is again during the PETSc build, configure.log

Thank you! I tried firedrake-install --slepc and it seems to work. I can import these packages now.
