一段时间以来，我一直在为这个烦人的未解决的外部符号而苦苦挣扎。我只是似乎没有找到错误在哪里，我的库似乎是链接的，但不知何故编译器看不到它。
2>win_main.obj : error LNK2019: unresolved external symbol "void * __cdecl nedalloc::nedmalloc(unsigned int)" (?nedmalloc@nedalloc@@YAPAXI@Z) referenced in function "private: static void * __cdecl Seventh::AllocatedObject::allocateBytes(unsigned int)" (?allocateBytes@AllocatedObject@Seventh@@CAPAXI@Z)
2>win_main.obj : error LNK2019: unresolved external symbol "void __cdecl nedalloc::nedfree(void *)" (?nedfree@nedalloc@@YAXPAX@Z) referenced in function "private: static void __cdecl Seventh::AllocatedObject::deallocateBytes(void *)" (?deallocateBytes@AllocatedObject@Seventh@@CAXPAX@Z)
2>C:\Users\X\X\X\SeventhEngine\Debug\SeventhEngineExamples.exe : fatal error LNK1120: 2 unresolved externals
我正在尝试链接nedmalloc dll 导出的库，我已经使用框架依赖项链接了它，并将其包含在 Additional Libraries 中。NEDMALLOC_DLL_EXPORTS我还使用确保__declspec(dllexport)标志编译了库。
如果您想查看，可以查看完整的源代码（包括 VS2010 解决方案和项目）：

我几乎可以肯定这是一个设置问题。此外，请随时发布有关此设置的任何建议和意见。
提前致谢。
