Bug#1018785: Problem with python3-dolfinx-real or libfftw3_mpi.so.3

[Torquil Macdonald Sørensen]

Package: python3-dolfinx-real
Version: 1:0.4.1-4+b1

If I try to import the dolfinx package in a python3 session, I get the following error:

$ python3
Python 3.10.6 (main, Aug 10 2022, 11:19:32) [GCC 12.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import dolfin
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'dolfin'
>>> import dolfinx
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/usr/lib/petsc/lib/python3/dist-packages/dolfinx/__init__.py", line 33, in <module>
     from dolfinx import common
   File "/usr/lib/petsc/lib/python3/dist-packages/dolfinx/common.py", line 10, in <module>
     from dolfinx import cpp as _cpp
ImportError: /usr/lib/x86_64-linux-gnu/libfftw3_mpi.so.3: undefined symbol: fftw_join_taint
>>>

I'm not sure if this is a problem with python3-dolfinx-real or libfftw3-mpi3. Please reassign
if necessary. I have libfftw3-mpi3 version 3.3.8-2 installed.

Best regards,
Torquil Sørensen
