OK, I'm new at this so please bear with me.
First off, I'm using boost::python so what low level functions do you mean
(can you give me one name so I know where to start looking)?
Second, what I did is the following:
Created an exe file (SimplePython.exe ) what has a standard greet() function
and the boost::python declaration:
I run the exe which feeds the interpreter with the script (via
To which the interpreter returns an exception saying "ImportError: No module
Can this be a path problem, do I somehow need to specify a dll/exe that has
c++ exported symbols?

Well, don't know for windows, but for Linux if your symbols are defined
inside your executable file, it works well ! Even your whole module can
be defined in your executable file. You just have to initialise it from
the C API with the low level functions (i.e. the ones who won't try to
look for a file named after your module name ...). Also, once your
module is loaded, every other "normal" import will just work !
