error LNK2019: unresolved external symbol ConnMgrConnectionStatus

在做今日插件的时候，添加网络层，可即使我添加了

#include <Ras.h>

#include <Connmgr.h>

#pragma comment ( lib, "Cellcore.lib" )

 

 #include <Ras.h> #include <Connmgr.h> #pragma comment ( lib, "Cellcore.lib" )

 

还是有下面的error：

 

 

1>ConnectManager.obj : error LNK2019: unresolved external symbol ConnMgrConnectionStatus referenced in function "private: int __cdecl ConnectManager::isConnectedNetwork(void)" (?isConnectedNetwork@ConnectManager@@AAAHXZ) 1>ConnectManager.obj : error LNK2019: unresolved external symbol ConnMgrEstablishConnectionSync referenced in function "private: int __cdecl ConnectManager::EstablishConnectionImpl(void)" (?EstablishConnectionImpl@ConnectManager@@AAAHXZ) 1>ConnectManager.obj : error LNK2019: unresolved external symbol ConnMgrReleaseConnection referenced in function "private: void __cdecl ConnectManager::CloseAllConnection(void)" (?CloseAllConnection@ConnectManager@@AAAXXZ) 1>Windows Mobile 5.0 Pocket PC SDK (ARMV4I)/Debug/memwatcher.dll : fatal error LNK1120: 3 unresolved externals 

 

 

工程属性linker->input->Ignore all default libraries->选NO里面去掉/NODEFAULTLIB就ok啦。"

或者linker->input->Additional Dependencies 中添加Cellcore.lib。
