Stroustrup的Graph.h

Question

我正在通過Stroustrup的「Programming Principles ...」的方式工作。我試圖獲得一個簡單的窗口程序編譯，並沒有在Linux或Windows上運氣。

最終，在多次出現問題後，我試圖將Graph.h包含在他的網站中，而不是其他的。我的錯誤是如下（我不知道，因爲我認爲他的代碼是正確的現在給做）

不知道這是否是失禮粘貼我的代碼，但無論如何。 我到處尋找，並試圖兩天。我現在感到非常沮喪。請幫忙。

Answer 1

您是否包含正確的Point.h（Graph.h取決於Point.h）？在找到「原理」示例之前，編譯器可能會找到其他一些Point.h文件。

g++ -M Window.cpp 

可能會幫助您確定。

我拉低了整個例如，發現我確實有修復Graph.h兩行得到它來編譯，但他們無關，與你在得到錯誤的行，Point.h，或Point類型。

在140-142 Graph.h行，我不得不改變：

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&); 

我假設你已經做到了這一點，因爲編譯器越來越過去那些行不投訴。在此修復之後，Window.cpp編譯正常（但不鏈接，因爲我沒有構建該示例所依賴的庫）。

我用MinGW 4.5.1做了這個。
