Hello,

I am having some trouble getting Paraview 5.6.3 to compile on Ubuntu 20.04. This is the version packed in the v2006 ThirdParty directory.


If I use the command

./makeParaview -mpi > log.makePV 2>&1

it works fine and compiles.


Ideally I want it compiled with python, so I am trying

/makeParaView -mpi -python3 -python-lib /usr/lib/x86_64-linux-gnu/libpython3.8.so.1.0 > log.makePV 2>&1

This crashes with some errors, see the whole file here. I think the relevant errors are these lines:

make[2]: *** [VTK/ThirdParty/mpi4py/vtkmpi4py/CMakeFiles/mpi4py.MPI.dir/build.make:63: VTK/ThirdParty/mpi4py/vtkmpi4py/CMakeFiles/mpi4py.MPI.dir/src/MPI.c.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:19613: VTK/ThirdParty/mpi4py/vtkmpi4py/CMakeFiles/mpi4py.MPI.dir/all] Error 2

I'm having real trouble trying to solve it, though.


Is anyone able to offer a solution?


Thank you!

I have managed to fix this. The problem was that mpi4py can't compile with the version of OpenMPI provided with Ubuntu 20.04 (4.0.3) until a small change is made to the file ParaView-v5.6.3/VTK/ThirdParty/mpi4py/vtkmpi4py/src/lib-mpi/config/openmpi.h


You need to add a new entry towards the bottom of the file:

#ifOMPI_NUMVERSION >= 40000
#undefPyMPI_HAVE_MPI_LB
#undefPyMPI_HAVE_MPI_UB
#endif/* OMPI >= 4.0.0 */

So that it matches the file here: https://bitbucket.org/mpi4py/mpi4py/...nfig/openmpi.h
