swig source compilation fails

[Philippe Piot]

Hi, I am trying to compiled fenisc on MAC 10-12.6. All packages compiled fine until the swig source part of the msh compilation. I have the error below. Somehow some files appear to be missing in dolfin/swig directory. Should these have been produced during the dolfin compilation? I am using swig version 3.0.12 and trying to compile msh version 2018.1.0.dev0. Thank you for any hint (I tried to poke around but I am not very familiar with swig).

laser few lines of the "cmake .." command:

Hi,

swig backend has been recently removed by upstream DOLFIN, and I think it will be removed shortly from mshr too @benjamik

In the meantime, you should compile mshr with the cmake option

-DENABLE_SWIG_BINDINGS:BOOL=OFF

If you are planning on using mshr from python, you should also manually install the pybind11 wrappers for mshr using the setup.py script in the python subfolder.

HTH,

Francesco

a user from the google mailing list suggested to add -DENABLE_SWIG_BINDINGS:BOOL=OFF in the cmake.
