很多问题似乎是重复的,但这不是。这是.lib链接错误,而不是.obj链接错误。
错误代码:
1>msvcprtd.lib(locale0_implib.obj) : error LNK2019: unresolved external symbol __imp__free_dbg referenced in function "public: static void __cdecl std::_Fac_node::operator delete(void *)" (??3_Fac_node@std@@SAXPEAX@Z)
1>msvcprtd.lib(locale0_implib.obj) : error LNK2019: unresolved external symbol __imp__malloc_dbg referenced in function "public: static void * __cdecl std::_Fac_node::operator new(unsigned __int64)" (??2_Fac_node@std@@SAPEAX_K@Z)

我忘记了核心库总是需要链接。
只需添加核心库依赖项(名为
$(CoreLibraryDependencies)
)或继承Additional Dependencies
字段的默认值(例如,这是Visual Studio创建的选项)。或者,这是需要链接的库列表(例如,发布版本):
