Hi,

I want to compile SU2 with python wrapper support. Therefore I installed mpi4py, all path variables are set properly.

Compilation process:

1: ./meson.py build -Denable-autodiff=true -Denable-directdiff=true -Denable-pywrapper=true --reconfigure

./ninja -C build install


during compilation I get this error:

[742/795] Generating 'SU2_PY/pySU2/fe26689@@_pysu2@sha/pySU2.cxx'.

any advice?

Hey hxaxtma,

I had this problem too. I think it's an error from SWIG. I was able to fix it by using version 3.0.12 of SWIG. Hope this helps!
