[Ethereal-dev] _DllMain@12 already defined

[li]

I make a VC++ project to compile ethereal to a DLL, finally, I got this error -------------------------------------------- single-threaded and multithreaded libraries   mfcs42d.lib(dllmodul.obj) : error LNK2005: [EMAIL PROTECTED] already defined in MSVCRTD.lib(dllmain.obj) mfcs42d.lib(dllmodul.obj) : warning LNK4006: [EMAIL PROTECTED] already defined in MSVCRTD.lib(dllmain.obj); second definition ignored --------------------------------------------   I see the MSDN explanation One of the following may be a cause: The most common cause of this error is accidentally linking with both the single-threaded and multithreaded libraries. Ensure that the application project file includes only the appropriate libraries and that any third-party libraries have appropriately created single-threaded or multithreaded versions. The given symbol was a packaged function (created by compiling with /Gy) and was included in more than one file but was changed between compilations. Recompile all files that include the symbol. The given symbol was defined differently in two member objects in different libraries, and both member objects were used. An absolute was defined twice, with a different value in each definition. whether I linking with both the single-threaded and multithreaded libraries or DLLmain define twice?   could you tell me how to solve it?   if you need source code, I will send it to you?     Frank Li
