Boost python允许您以非常紧密的集成方式将c 类公开给python-您甚至可以包装它们，以便可以从c 类派生python类，并将虚拟方法解析为python覆盖。

You can create a c++ object and pass a reference to it to an internal python interpreter like this:
#include <boost/shared_ptr.hpp>
#include <boost/make_shared.hpp>
#include <boost/python.hpp>
#include <string>
#include <iostream>
namespace bp = boost::python;
struct Foo{
Foo(){}
Foo(std::string const& s) : m_string(s){}
void doSomething() {
std::cout << "Foo:" << m_string << std::endl;
}
std::string m_string;
};
typedef boost::shared_ptr<Foo> foo_ptr;
BOOST_PYTHON_MODULE(hello)
{
bp::class_<Foo, foo_ptr>("Foo")
.def("doSomething", &Foo::doSomething)
;
};
int main(int argc, char **argv)
{
Py_Initialize();
try {
PyRun_SimpleString(
"a_foo = None\n"
"\n"
"def setup(a_foo_from_cxx):\n"
" print 'setup called with', a_foo_from_cxx\n"
" global a_foo\n"
" a_foo = a_foo_from_cxx\n"
"\n"
"def run():\n"
" a_foo.doSomething()\n"
"\n"
"print 'main module loaded'\n"
);
foo_ptr a_cxx_foo = boost::make_shared<Foo>("c++");
inithello();
bp::object main = bp::object(bp::handle<>(bp::borrowed(
PyImport_AddModule("__main__")
)));
// pass the reference to a_cxx_foo into python:
bp::object setup_func = main.attr("setup");
setup_func(a_cxx_foo);
// Now run the python 'main' function
bp::object run_func = main.attr("run");
run_func();
}
catch (bp::error_already_set) {
PyErr_Print();
}
Py_Finalize();
return 0;
}
