I have switched desktop to a newer machine, gcc version 8.3.0 (Ubuntu 8.3.0-6ubuntu1)

turning on MPI, I can no longer compile with the following failure:

/usr/bin/cc -DMPICH\_SKIP\_MPICXX -DOMPI\_SKIP\_MPICXX -DPyMPI\_MISSING\_MPI\_Status\_c2f -DPyMPI\_MISSING\_MPI\_Status\_f2c -DPyMPI\_MISSING\_MPI\_Type\_create\_f90\_complex -DPyMPI\_MISSING\_MPI\_Type\_create\_f90\_integer -DPyMPI\_MISSING\_MPI\_Type\_create\_f90\_real -D\_MPICC\_H -Dvtkmpi4py\_MPI\_EXPORTS -DVTK\_IN\_VTK -Dmpi4py\_MPI\_EXPORTS -I/local/apps/ParaView/ParaView-v5.6.0Build -I/local/apps/ParaView/ParaView-v5.6.0Build/VTK/ThirdParty/mpi4py -I/local/apps/ParaView/ParaView-v5.6.0/VTK/ThirdParty/mpi4py -I/usr/include/x86\_64-linux-gnu/mpich -I/usr/include/python3.7m -I/local/apps/ParaView/ParaView-v5.6.0/VTK/ThirdParty/mpi4py/vtkmpi4py/src -w -O2 -g -DNDEBUG -fPIC -o CMakeFiles/mpi4py.MPI.dir/src/MPI.c.o -c /local/apps/ParaView/ParaView-v5.6.0/VTK/ThirdParty/mpi4py/vtkmpi4py/src/MPI.c

I’d appreciate any advice. TIA

Jean,  
I think I hit the same problem recently. Are you trying to compile paraview 5.6 with python 3.7?

You’ll need to use python 3.6 for paraview 5.6. I think master works with python 3.7.

Hello Dan

indeed, I am using the default python3 of Ubuntu 19.04 (i.e. python 3.7).

I confirm that PV master compiles OK.
