boost python代码涉及静态和重载成员函数

Question

我正在尝试编译一些包含静态和重载成员函数的boost python代码。有什么提示吗？我只是无法使用函数上的指针编译它(以前从未这样做过(，但可能还有另一条路要走？

#include<iostream>
#include <boost/python.hpp>
#include <boost/python/raw_function.hpp>

namespace python = boost::python;

class ORM
{
public:
static void print() {std::cout << "Fou statique!!!!" << std::endl;}
static void print(std::string st) {std::cout << st << std::endl;}
static void print(std::string st1, std::string st2) {std::cout << st1 << std::endl; std::cout << st2 << std::endl;}
};
void (ORM::*print1)() = &ORM::print;
void (ORM::*print2)(std::string st) = &ORM::print;
void (ORM::*print3)(std::string st1, std::string st2) = &ORM::print;

BOOST_PYTHON_MODULE(politopy)
{
python::class_<ORM>("ORM")
.def("print", &ORM::print1).staticmethod("print")
.def("print", &ORM::print2).staticmethod("print")
.def("print", &ORM::print3).staticmethod("print")
;
}

以下更改对我有效：您需要#include <string>才能使用std::string。您也不需要将函数指针分配为ORM的成员，只需在函数指针分配中指定参数类型即可。当您声明BOOST_PYTHON_MODULE()时，输入必须与您的库名称(即libpolitopy(匹配。此外，始终使用Py_Initialize()从C++初始化Python。最后，您只需要在print的最终声明中包含一次.staticmethod()标记。

#include <iostream>
#include <string>
#include <boost/python.hpp>
#include <boost/python/raw_function.hpp>
namespace python = boost::python;
class ORM
{
public:
static void print() {std::cout << "Fou statique!!!!" << std::endl;}
static void print(std::string st) {std::cout << st << std::endl;}
static void print(std::string st1, std::string st2) { std::cout << st1 << std::endl; std::cout << st2 << std::endl;}
};
void (*print1)() = &ORM::print;
void (*print2)(std::string) = &ORM::print;
void (*print3)(std::string, std::string) = &ORM::print;

BOOST_PYTHON_MODULE(libpolitopy)
{
Py_Initialize();
python::class_<ORM>("ORM")
.def("print", print1)
.def("print", print2)
.def("print", print3).staticmethod("print");
}
