MacOS: Compiled successfully, but module is missing

[fhamborg]

I'm on MacOS 10.12.3 and followed the hints in the other issue on failing MacOS compilation (#19). Finally, I was able to get the compilation and python package setup run through, but I still cannot use the parser.

Sadly, I'm no expert on building BLLIP on Mac OS X (still). Is http://stackoverflow.com/questions/26958232/need-help-wrong-architecture-causing-app-to-crash-when-launching-in-ios-7-but helpful?

Unfortunately not, but I managed to avoid this problem by basically performing PyCharm remote development, i.e., I setup a Ubuntu VM which is now controlled by PyCharm. The code is executed on that VM rather than on MacOS. It's not good, but it works. I followed this guide: https://blog.jetbrains.com/pycharm/2015/03/feature-spotlight-python-remote-development-with-pycharm/

here is what I did to solve this problem on Mac el Capitan

1. of course, install swig with brew: brew install swig
2. in order to run: make (to compile), I need to specify the CC and CXX as stated in the README: CC=/usr/lib/bin/gcc-7 and CXX=/usr/lib/bin/g++-7
3. I tried to install the python package using pip install bllipparser, but got the same error. So, I decided to install from source code with python setup.py install. But the trick here is that I NEED to use the default CC and CXX (just open a new terminal :- ) )
4. Probably, one error (Expected in: flat namespace) will be returned, just add “‘-stdlib=libc++’” when building reranker_module in setup.py, instead of c++11. (https://stackoverflow.com/questions/16880571/why-does-clang-lack-forward-list)

Good luck ;-)
