GetCreatureInWorld function

[Prefect]

hi all, i have a problem, i use SD2 and i need this function, i set access to FindPlayer() function by _declspec(dllexport) :

        // Player access
       static _declspec(dllexport) Player* FindPlayer(ObjectGuid guid);

But when i set same to GetCreatureInWorld :

        static _declspec(dllexport) Creature*   GetCreatureInWorld(ObjectGuid guid)

I get a compile error :

8>ScriptMgr.obj : error LNK2001: unresolved external symbol ""public: static class std::list<class Map *,class std::allocator<class Map *> > ObjectAccessor::i_mapList" (?i_mapList@ObjectAccessor@@2V?$list@PEAVMap@@V?$allocator@PEAVMap@@@std@@@std@@A)"

What i need to do to allow use this function from SD2 ?

*Sorry for bad english
