CFD Online Discussion Forums - Error during compilation (python-wrapper)

Hello,

I tried to compile the SU2 code on a machine (OS:Centos7) using the following modules:
module purge
module load gcc/10.2.0 # gcc/10.2.0
module load python/3.9.7 # python/3.9.7 (compiled with gcc/10.2.0)
module load openblas/0.3.19-st # openblas 0.3.19 (Single threaded)
module load impi/2019.5.281 # IMPI MPI library
module load cmake
export CC=mpicc
export CXX=mpicxx
export CFLAGS=" -O2 -fPIC "
export CXXFLAGS=" ${CXXFLAGS} "
export PYTHONPATH=/uufs/chpc.utah.edu/sys/installdir/su2/pylib/3.9.7/lib/python3.9/site-packages:$PYTHONPATH

I used the following flags:
./meson.py mybuild -Dcustom-mpi=true -Dwith-mpi=enabled -Denable-mpp=true -Denable-openblas=true -Denable-pywrapper=true \
-Denable-autodiff=true -Denable-mixedprec=true --prefix=/uufs/chpc.utah.edu/sys/installdir/su2/7.2.1

Please be sure to add the $SU2_HOME and $SU2_RUN environment variables,
and update your $PATH (and $PYTHONPATH if applicable) with $SU2_RUN

Based on the input to this configuration, add these lines to your .bashrc file:

export SU2_RUN=/uufs/chpc.utah.edu/sys/installdir/su2/7.2.1/bin
export SU2_HOME=/uufs/chpc.utah.edu/sys/srcdir/su2/7.2.1
export PATH=$PATH:$SU2_RUN
export PYTHONPATH=$PYTHONPATH:$SU2_RUN

Use './ninja -C mybuild install' to compile and install SU2

Message: To run SU2 with Mutation++ library, add these lines to your .bashrc file:

export MPP_DATA_DIRECTORY=$SU2_HOME/subprojects/Mutationpp/data
export LD_LIBRARY_PATH=$SU2_HOME/<build_dir>/subprojects/Mutationpp

At the end of the compilation I obtained the following error:
Build targets in project: 21

SU2 7.2.1 "Blackbird"

Subprojects
Mutationpp: YES

Found ninja-1.10.0.git at /uufs/chpc.utah.edu/sys/srcdir/su2/7.2.1/ninja

./ninja -C build install

ninja: build stopped: subcommand failed.

When I removed the option "-Denable-pywrapper=true" from the meson CMD line I was able to compile the code.

Before compiling the SU2 code I installed MPI4PY with the same version of gcc and impi.
module purge
module load gcc/10.2.0
module load python/3.9.7
module load impi/2019.5.281

export CC=mpicc
export CXX=mpicxx
export CFLAGS=" -m64 -O2 -fPIC "
export CXXFLAGS=" ${CFLAGS} "

cd /uufs/chpc.utah.edu/sys/srcdir/su2/pylib/mpi4py/3.1.3
python3 setup.py build
python3 setup.py install --prefix=/uufs/chpc.utah.edu/sys/installdir/su2/pylib/3.9.7
export PYTHONPATH=/uufs/chpc.utah.edu/sys/installdir/su2/pylib/3.9.7/lib/python3.9/site-packages:$PYTHONPATH

Any idea what I should do to resolve the compilation issue?

Thank you,

Wim
