Hi All,

It seems that the AD build fails with OpenMPI 4.0.0. I don't really know where the source of error is, but I suspect it's with CGNS and how it's handled by OpenMPI?

The error is as follows:

In file included from ../../../Common/lib/../src/../include/./mpi_structure.hpp:42:0,
from ../../../Common/lib/../src/../include/geometry_structure.hpp:41,
from ../../../Common/lib/../src/fem_cgns_elements.cpp:34:

Makefile:13: recipe for target 'install-SU2_AD' failed

My pregonfigure command is:

export CXXFLAGS="-O3" && sudo ./preconfigure.py --enable-autodiff --prefix=/home/akb1r19/CFD_Solvers/SU2/Instldir --enable-mpi --with-cc=/usr/local/bin/mpicc --with-cxx=/usr/local/bin/mpicxx &>preconfig.out

Attaching the whole make output, and the preconfigure log files here too.
I have successfully been able to compile with AD on a cluster with Intel MPI (2017.4.239). I run the exact same commands and it compiles without issue. I haven't tried mpich yet to see if the error persists. Any thoughts?

Thanks,
Amir

I have a similar problem, would be a great help if anyone could help here.

It has occurred to me that perhaps I need to compile hdf5 on my system for the parallel integration of CGNS with OpenMPI?

I'm going to try it tomorrow and report back.

Hi all,

For those who are facing the same problem, I tried with OpenMPI 3.0.3 instead of 4.0.0 and the AD build was succesful.

Please refer to issue #659 on SU2's GitHub repository for more info.
