Stroustrup的Graph.h

Question

我正在通过Stroustrup的“Programming Principles ...”的方式工作。我试图获得一个简单的窗口程序编译，并没有在Linux或Windows上运气。

最终，在多次出现问题后，我试图将Graph.h包含在他的网站中，而不是其他的。我的错误是如下（我不知道，因为我认为他的代码是正确的现在给做）

不知道这是否是失礼粘贴我的代码，但无论如何。 我到处寻找，并试图两天。我现在感到非常沮丧。请帮忙。

您是否包含正确的Point.h（Graph.h取决于Point.h）？在找到“原理”示例之前，编译器可能会找到其他一些Point.h文件。

g++ -M Window.cpp 

可能会帮助您确定。

我拉低了整个例如，发现我确实有修复Graph.h两行得到它来编译，但他们无关，与你在得到错误的行，Point.h，或Point类型。

在140-142 Graph.h行，我不得不改变：

private: // prevent copying 
    Vector_ref(const Vector&); 
    Vector_ref& operator=(const vector&); 

到：

private: // prevent copying 
    Vector_ref(const Vector_ref&); 
    Vector_ref& operator=(const Vector_ref&); 

我假设你已经做到了这一点，因为编译器越来越过去那些行不投诉。在此修复之后，Window.cpp编译正常（但不链接，因为我没有构建该示例所依赖的库）。

我用MinGW 4.5.1做了这个。
