VS 2008 C++錯誤C2059和C2238

Question

我試圖移植在linux/g ++中開發的程序/遊戲，以便它在Windows 7 VS 2008 C++上運行。該程序使用諸如OpenGL，SDL和Boost等庫。

我已經解決了很多錯誤，但我有點卡在這一個。

我得到錯誤代碼C2059和C2238。實際的錯誤信息是：

TractorBeamShot.cpp 

的ViewFrustum.h文件如下：

/** 
    * viewFrustum: It's got useful functions to cull items that aren't in your view frustum 
    * 
    * 2-7-11 
    * CPE --- 
    */ 

    #ifndef __VIEW_FRUSTUM_H__ 
    #define __VIEW_FRUSTUM_H__ 

    #include "Items/Object3D.h" 
    #include "Utility/Plane.h" 
    #include "Utility/Matrix4.h" 
    #include <vector> 
    #include <set> 

    class ViewFrustum { 
    public: 

     ViewFrustum(); 
     virtual ~ViewFrustum(); 

     /* Takes in a list of all the Object 3D's around, and culls them down to only the ones 
     * that are inside the view frustum. 
     */ 
     virtual std::list<Drawable*>* cullToViewFrustum(std::vector<Drawable*>* all, bool skipParticles); 
     virtual std::list<Object3D*>* cullToViewFrustum(std::vector<Object3D*>* all); 

     /* Prints out details about all of the planes of the view frustum. 
     */ 
     virtual void print(); 

    private: 
     Matrix4 projMatrix; 
     Matrix4 modelViewMatrix; 
     Plane* top; 
     Plane* bottom; 
     Plane* left; 
     Plane* right; 
     Plane* near; 
     Plane* far; 

     /** 
     * A modified version of chedDrawableOutside, used by the AI. This stops the 
     * AI from targeting Drawable objects which are slightly outside the field 
     * of view, which still need to be drawn. 
     */ 
     bool checkTargetableOutside(Drawable* obj); 

     /* Returns true if the Drawable object is completely outside of the 
     * view frustum planes. 
     * Returns false if it's even part-way inside. 
     */ 
     virtual bool checkDrawableOutside(Drawable* obj); 
    }; 

    #endif 

違規的線（40-41）是：

Plane* near; 
    Plane* far; 

這是一種令人困惑因爲ViewFrustum obj已經編譯好了，但是當它到達UDP_Server.cpp和UDP_Client.cpp時，它會拋出一個錯誤。我不確定它是否重要，但UDP類使用Boost的異步和序列化模塊。我知道Boost有時會發出奇怪的警告，但我不確定Boost是否必須對此錯誤執行任何操作。

如果有人有任何想法，爲什麼這是或如果你需要更多的代碼張貼，請讓我知道。

有機會在此之前包含一個windows標頭，並且near和far被定義在那裏。這些都是16位時代的（遺留）事情。
