Using the code generated by Py ++ as a Python extension

I need to wrap an existing C ++ library for use in Python. After reading this answer on choosing the appropriate method for porting C ++ for use in Python , I decided to go with Py ++.

I went through the tutorial for Py ++ using the tutorial files, and got the expected result in generated.cpp, but I don’t know. I did not understand what to do to actually use the generated code as an extension that I can import into Python. I'm sure I need to compile the code now, but with what? Should I use bjam ?

Py ++ generates the syntax that you use with boost :: python to create python entry points in your application. Assuming everything went well with Py ++, you need to load the Boost framework and add the boost and boost :: python lib directory to your project, and then compile with the cpp created using Py ++.

You can use any build system you want for your project, but boost is built using bjam. You need to choose whether you want a static lib or dynamic boost python lib, and then follow the instructions for creating boost here .

If on windows you need to change the extension in your built-in library from .dll to.pyd. And yes, it must be a library project, it does not work with executable files.
