This works:

$ swig -v -python -c++ -o swiginac_wrap.c swiginac.i
Language subdirectory: python
Search paths:
   ./
   ./swig_lib/python/
   /opt/local/share/swig/3.0.7/python/
   ./swig_lib/
   /opt/local/share/swig/3.0.7/

In setup.py I found these lines:


# The command line argument for running swig in c++ mode has changed from
# Python 2.3 to 2.4. We support both.
swig_opt = '--swig-cpp'
if distutils.__version__ >= '2.4': swig_opt = '--swig-opts=-c++'

if argv[1] == 'build':
    argv[1] = 'build_ext'
if argv[1] == 'build_ext':
    argv.insert(2, swig_opt)

    
It should be adding ‘-c++’ to the swig command, but for some reason it is not:
