LIBCMTD.lib问题(在线等)
程序中用到了多线程,
如果想强行链接,中VS2005中如何设置?
以下为运行错误:

[解决办法]
在工程属性设置里的Linker设置中把LIBCMT.lib设置为忽略试试。
[解决办法]
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：
#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, .............
[解决办法]
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
