Attempting to use an MPI routine before initializing MPICH
I built ParaView from source on FreeBSD-14, with MPI enabled. Only MPICH-3.4.3 is installed on this machine, no OpenMPI nor any other MPI implementation. MPI4PY has been compiled on this machine, against MPICH. Compilation and installation are fine, without errors. But trying to launch paraview produces the error "Attempting to use an MPI routine before initializing MPICH", and then the program exits.
Any idea of a possible origin of this error?
