使用boost :: python将C++类实例传递给python

sudo apt-get install libboost-all-dev python3-dev

#include<boost/python.hpp>
#include<Python.h>

class MyClass {
public:
    MyClass(int value) : value_(value) {}
    int getValue() const { return value_; }
private:
    int value_;
};

BOOST_PYTHON_MODULE(my_module) {
    using namespace boost::python;
    class_<MyClass>("MyClass", init<int>())
        .def("getValue", &MyClass::getValue)
        ;
}

g++ -shared -o my_module.so my_module.cpp -lboost_python3 -lpython3.8

import my_module

my_instance = my_module.MyClass(42)
print(my_instance.getValue())
