I'm trying to wrap some basic C++ code. I tried to follow the
directions on the wiki, but I found them to be unclear and incomplete.
I also noticed a thread about this on Cython-dev, but it doesn't seem
to have been resolved. As a total rookie with Cython and wrapping
code in general, it would be nice to have a step by step example of
the process that is illustrative of how to wrap a C++ library,
including:
1) Source of the header file (Rectangle.h)
2) Source of the implementation file (Rectangle.cpp)
3) Source of the setup file (setup.py)
4) Source of the ??? file (Rectangle.pyx)
5) shell commands necessary prior to being able to import the
Rectangle class into python
6) example of using the wrapped C++ library inside the python interpreter
Things that were not helpful in the setup.py were things like:
include_dirs=[...], # usual stuff
libraries=[...], # ditto
extra_link_args=[...], # if needed
As an example of how to wrap a C++ class, I don't think extras that
aren't well explained help the situation. From the wiki, it wasn't
clear what exactly belonged in the .pyx file. It would be nice if
this could be clarified.
I think I can piece together steps 1), 2), 3) from the wiki and from
the previous thread on the subject, but steps 4), 5), and 6) are still
unclear to me. It would be a great help if these steps could be shown
explicitly. Can anybody help me out on how to do this?
Thanks,
~Luke
