我的任务
分享这个错误怎么办呢?warning LNK4006: _DllMain@12 already defined in Test2.obj; second definition ignored
我在支持MFC的dll中定义了 定义了dllmain函数
,就报错
DLLMODUL.OBJ : warning LNK4006: _DllMain@12 already defined in Test2.obj; second definition ignored
Creating library Release/MyGina.lib and object Release/MyGina.exp
网上查了很多资料,但好象都没有效果
不知道哪位能解决呢?
还有支持MFC的dll 在windows 登陆前调用能用MFC中的函数吗?
谢谢啊

Test2.obj
产生该文件的cpp中已经定义过dllmain了
重复定义了

mfc dll的app类中封装了dllmain,如果需要要自己写dllmain,建立工程的时候选win32 dll
第二个问题,用release版本发布后mfc dll和win32 dll应该一养的.

你创建的应该是MFC扩展DLL
向导已经为你生成了DLLMain入口函数
extern "C" int APIENTRY
DllMain(HINSTANCE hInstance, DWORD dwReason, LPVOID lpReserved)
{
// Remove this if you use lpReserved
UNREFERENCED_PARAMETER(lpReserved);
if (dwReason == DLL_PROCESS_ATTACH)
{
TRACE0("54.DLL Initializing!\n");
// Extension DLL one-time initialization
if (!AfxInitExtensionModule(My54DLL, hInstance))
return 0;
// Insert this DLL into the resource chain
// NOTE: If this Extension DLL is being implicitly linked to by
// an MFC Regular DLL (such as an ActiveX Control)
// instead of an MFC application, then you will want to
// remove this line from DllMain and put it in a separate
// function exported from this Extension DLL. The Regular DLL
// that uses this Extension DLL should then explicitly call that
// function to initialize this Extension DLL. Otherwise,
// the CDynLinkLibrary object will not be attached to the
// Regular DLL's resource chain, and serious problems will
// result.
new CDynLinkLibrary(My54DLL);
}
else if (dwReason == DLL_PROCESS_DETACH)
{
TRACE0("54.DLL Terminating!\n");
// Terminate the library before destructors are called
AfxTermExtensionModule(My54DLL);
}
return 1; // ok
}
你不能再整一个DLLMain

有类已经实现了dllmain
