程序中用到了多线程,
假如想强行链接,中VS2005中如何设置?

以下为运行错误:

网友回复:在工程属性设置里的Linker设置中把LIBCMT.lib设置为忽略试试。
网友回复:指定编译选项/MDd
并忽略LIBCMT.lib
网友回复:在你用到多线程的 .cpp 文件中加上一句：
#pragma comment(lib, "LIBCMT.LIB")

比如我的一个程序中使用的：

C/C code

#include "D3Dapp.h"

#include <process.h>

#pragma comment(lib, "LIBCMT.LIB")



//后台绘图线程

void Paint(void * obj)

{

    C3Dapp * C3Dobj = (C3Dapp *)obj;



    C3Dobj->Render();

}



HRESULT C3Dapp ::InitSence()

{

    CUSTVERTEX *                pWriteData;



    if (FAILED(m_lpD3dDevice->CreateVertexBuffer(sizeof(CUSTVERTEX) * 3,

    .............

网友回复:在哪里指定编译选项/MDd ?
初用此IDE不熟,谢谢!

网友回复:右击工程－－属性－－配置属性－－C/C －－代码生成－－运行时库－－多线程调试（/MDd）
右击工程－－属性－－配置属性－－链接器－－输入－－忽略特定库
