VS2005类向导的问题

李锦俊 — Sun, 31 Dec 2006 07:51:00 GMT

以前用VS 6和VS2003，类向导生成的都是虚析构函数，但是到了VS2005，默认就不是虚析构函数了。
这会带来什么问题？我今天就遇到了一次。当我用VS2005类向导生成一个类，如
class BaseClass
{
public:
    BaseClass(){};
   ~BaseClass(){};
   virtual void VFun() = 0;
}

然后，再生成一个类继承于他
class ProblemClass : public BaseClass
{
public:
    ProblemClass (){};
   ~ProblemClass (){};
   virtual void VFun(){};
}

然后，执行以下代码：

BaseClass *pClass = new ProblemClass ;
delete pClass ;

如无以外，在delete的时候就会出现堆错误

今天碰到了LINK2005的问题

烦人的错误。。搞了一个多小时才解决，写下来记录一下。

解决办法：保证需要链接的几个项目的运行时库使用同一个类型就OK了！例如我的工程中有GameCore、Plugin_D3D9RenderSystem、Plugin_Win32Platform三个工程，那么就去设置每个工程的C/C++ ->代码生成->运行时库，统一设置成“多线程 DLL(/MD)”，就可以了。如果其中一个不是MD，就会出现以下的错误。很烦人。希望同样遇到这个问题的朋友能少走弯路

以下是链接错误信息：
