[Boost.Python] 在C++中调用python

python源程序如下(example.py)

class goods:
    def __init__(self, price):
        self.price = price

    def sale(self, amount):
        return self.price * amount


C++源程序如下(example.cpp)

#include <iostream>
#include <string>
#include <boost/python.hpp>
#include <boost/ref.hpp>

using namespace boost::python;

int main(int argc, char* argv[])
{
    Py_Initialize();

    object sys = import("sys");
    object path = sys.attr("path");
    path.attr("append")(".");

    object example = import("example");
    object goods = example.attr("goods")(1.23);
    object rc = goods.attr("sale")(1.1);

    std::cout << extract<float>(rc) << std::endl;

    return 0;
}


编译：g++ example.cpp -I/usr/include/python2.6 -lboost_python-mt-python26 -lpython2.6
