Installation Error on WSL

[calvin-reedy]

Hi! I've been trying to install Firedrake on WSL and even after running the update script, when I activate the virtual environment and run the "make check" command for the unit tests as suggested in the installation instructions, I get the following output:

Running serial smoke tests

Any suggestions?

Hi @calvin-reedy, sorry for taking so long to get back to you. This error looks a bit like you are using a petsc4py linked against an older version of PETSc. Running

$ ldd $VIRTUAL_ENV/lib/python3.10/site-packages/petsc4py/lib/default/*.so | grep petsc

should confirm this (I may have gotten the path wrong slightly). The fix would then I think be to run

$ pip cache remove petsc4py
$ firedrake-update

However, I do not actually recommend that you do this. We are deprecating firedrake-install today and will have an alternative, hopefully more robust, system instead. I recommend waiting and following those instructions.
