I want to write a wrapper for C++ code. My ultimate goal is to access classes and their functions written in C++ using python but right now, I am just trying to write a simple wrapper for hello world program. So, I looked online and saw boost.python is able to perform such feat. Their tutorial though is not so clear. I am trying to follow it but I am getting lost. Also the tutorial is based on windows systems and i am using mac, so it is creating more confusion for me.
I installed boost and bjam through homebrew. 

brew install boost --with-python
brew install bjam

the code i am trying to wrap. 

#include <iostream>
char const* greet(){
    return "hello world!"
}

Can you help me how to proceed with this?

For now, I downloaded Jammrootscript as directed in tutorial and edited the use-project boostto the current location of boost(/usr/local/Cellar/boost)
then, when i try to run bjam from terminal, i get following error

Jamroot:17: in modules.load
*** argument error

    i never used boost but you can use something called ctypes. this link has a complete example. Good luck Commented Nov 2, 2015 at 15:04
  • @Saraiva hey thanks for pointing out ctypes but it seems ctypes is a lengthy process as I have quite elaborate classes to work with. I was hoping if i could figure out boost.python, I can do the warping easily. Commented Nov 2, 2015 at 15:18
  • i see. Anyway, tipically in a wrapper you only expose a well-defined interface. Thats how ctypes work and how (for instance) JNI works (i recently had to create a Java wrapper for a c++ code). No matter how complex the existing code is remember that a wrapper accesses the wrapped code through simple well-defined calls (thus the ctypes). Good luck with the boost, i'm sure you will make it work Commented Nov 2, 2015 at 15:25
  • check out this link it looks like it might help Commented Nov 2, 2015 at 15:33
  • Hey thanks for the links. but sadly the boost.python tutorial is still out of my head and not yet working. i am killing myself over it now -.- Commented Nov 3, 2015 at 12:08
