Embedding/Extending Python in C++

[Kirby]

I'm trying to add some type of scripting capabilites to a big C++ project, and my boss told me to look into Python as an option. Niether one of us know much about, but it seems like I can either embed or extend it. Embedding can run Python, and extending can make calls to a dll.

What I need is the capability to run Python from an executable, and make calls to functions in the executable from Python.

Possible, or should I look somewhere else?

One simple way to run python, or anything else, is going to fork a process and run a python interpreter. On linux, look at system(). On Windows, look at spawn().

I can embed and run the interpreter fine from C++, but I can't find out how to make function calls back to the executable. On Windows btw.

Have you looked into SWIG? I think there is a Windows port.

Just quickly glancing at it, SWIG may do the trick. :thumbsup:

If not, I guess I'll be back.

Not sure if this is exactly what you're looking for, but should give http://www.boost.org/doc/libs/.../python/doc/index.html a look.

you can't just plug one end into the other ?

I looked through boost pretty well since we're already using it, but couldn't find anything too useful.

That's what she said?

Well, SWIG still requires you to use a dll. :|

At this point, the only option I see is to embed python into the exe, then use sockets to talk back to it. Seems roundabout, but I'm out of ideas.
