Anaconda/Python

[jacobwilliams]

The SWIG-produced Python interface doesn't work on a Mac with an Anaconda distribution of Python.

A workaround is to add -undefined dynamic_lookup to the linker properties in swig/CMakelists.txt like so:

Replace:

SWIG_LINK_LIBRARIES(PyOFInterfaceC ${PYTHON_LIBRARY} OpenFrames_Interface_C)

with:

  if(APPLE)
    # for anaconda
    SWIG_LINK_LIBRARIES(PyOFInterfaceC OpenFrames_Interface_C)
    SET_TARGET_PROPERTIES(${SWIG_MODULE_PyOFInterfaceC_REAL_NAME} PROPERTIES LINK_FLAGS "-undefined dynamic_lookup")
  else()
    SWIG_LINK_LIBRARIES(PyOFInterfaceC ${PYTHON_LIBRARY} OpenFrames_Interface_C)
  endif()

And this:

SWIG_LINK_LIBRARIES(PyOFInterfaceIFORT ${PYTHON_LIBRARY} OpenFrames_Interface_IFORT)

with this:

    if(APPLE)
      # for anaconda
      SWIG_LINK_LIBRARIES(PyOFInterfaceIFORT OpenFrames_Interface_IFORT)
      SET_TARGET_PROPERTIES(${SWIG_MODULE_PyOFInterfaceIFORT_REAL_NAME} PROPERTIES LINK_FLAGS "-undefined dynamic_lookup")
    else()
      SWIG_LINK_LIBRARIES(PyOFInterfaceIFORT ${PYTHON_LIBRARY} OpenFrames_Interface_IFORT)
    endif()

I think this breaks linking with the Python.org distribution though. Ideally, it should work for both.
