[C++-sig] A question about PyImport_AppendInittab

[Qun Cao]

Hi Everyone,

I am adopting the code in boost/libs/python/test/embedding.cpp for my
project.  Here is my question, in
embedding.cpp we have:

 if (PyImport_AppendInittab("embedded_hello", initembedded_hello) == -1)
        throw std::runtime_error("Failed to add embedded_hello to the
interpreter's "
                                 "builtin modules");

I noticed #define BOOST_PYTHON_MODULE BOOST_PYTHON_MODULE_INIT in
module.hpp file, so I guess "initembedded_hello" here is a pointer to
the module "embedd_hello".  However, in my project,
BOOST_PYTHON_MODULE{} definition code sits
in a different class class_wrapper.cpp than main.cpp, does that mean i
need to include class_wrapper.cpp in main.cpp?  That gives me wierd
problem in compilation though.

Also, generally, why main.cpp needs to know how a C++ wrapper module
is created?  Isn't it enough to tell it that there exists a python
module in class.dll and the embedded python interpreter will just
understand everything from there?

Thanks for any insights,
Qun
