Dear all,
I'm trying to compile the 9.5.1 version without MPI on Ubuntu 20.04 but I'm
getting the following error:
/home/tom/p/dealii/source/lac/petsc_communication_pattern.cc: In member

and so on.
mpi_type_id_for_type is defined in source/base/mpi.cc, but inside #ifdef
... #endif:
#ifdef DEAL_II_WITH_MPI
// Provide definitions of template variables for all valid
instantiations.

#endif
which should't be defined without MPI if I'm correct so the compilation
error is about right.
Version 9.4.x compiles without problem.
Any advice please? Thanks
Tom
