Невозможно скомпилировать сгенерированную Swig оболочку для расширения C ++ Python

Привет, я пытаюсь расширение Swig Python, в C ++, пример — на странице Mit

Мой заголовок — shape.h

#include <iostream>

class Shape
{
public:
Shape()
{
nshapes++;
}
~Shape()
{
nshapes--;
}
double  x, y;
void    move(double dx, double dy);
virtual double area() = 0;
virtual double perimeter() = 0;
static  int nshapes;
};

class Circle : public Shape {
private:
double radius;
public:
Circle(double r) : radius(r) { };
virtual double area();
virtual double perimeter();
};

class Square : public Shape {
private:
double width;
public:
Square(double w) : width(w) { };
virtual double area();
virtual double perimeter();
};

Соответствующий интерфейсный файл — shapeModule.i

%module shapes

%{
#include "shapes.h"%}

/* Let's just grab the original header file here */
%include "shapes.h"

Сначала я запустил команду swig — swig -c ++ -python shapeModule.i

Это сгенерировало следующие 2 файла —
shapesModule_wrap.cxx
shapes.py

Затем я запустил компилятор g ++ — g ++ forms.h shapeModule_wrap.cxx -I / usr / include / python2.7

Но я получаю много ошибок, которые я не могу понять —

Я не могу понять, в чем проблема. Я новичок в глотке, поэтому, пожалуйста, предоставьте несколько указателей. Плюс любой знает любые рабочие примеры с пошаговым руководством, которое также будет оценено.

большое спасибо

update — в ответе @ m7thon исправлены ошибки компиляции. Теперь я получаю ошибку при импорте модуля в Python —

Firstly, thanks for the response. that fixed my errors. :)

Бит Я получаю следующую ошибку при импорте —

Я запустил нм в файле _shapes.so, и я получил следующее для символа —

         U _ZN5Shape4moveEdd

Итак, я понимаю, что это не определено. Нашел об этом — Вот но все еще не уверен, как это исправить.
