[petsc-users] Configure error with PETSc 3.17.4 on Ubuntu 22.04

[David Knezevic]

I get a configure error when building PETSc 3.17.4 on Ubuntu 22.04. The
configure.log is attached.

This error seems to only occur when we use --with-clanguage=cxx. We need to
use that object when building with complex numbers.

Guidance on how to resolve this would be most appreciated.

Thanks,
David
