C++ Visual Studio 2012 链接器错误？

Question

我是 C++ 的新手，我正在使用 SFML 设置一个项目，它工作正常，根据 Visual Studio，我没有代码问题，但是当我调试时，我收到以下错误消息:

Error 1 error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall sf::String::String(char const *,class std::locale const &)" (_imp??0String@sf@@QAE@PBDABVlocale@std@@@Z) referenced in function "public: static void __cdecl Game::Start(void)" (?Start@Game@@SAXXZ) c:\Users\Harley\cppprojects\Pong\PongSFML\PongSFML\Game.obj PongSFML

我已经做了很多研究来尝试解决这个问题，但没有任何建议奏效或根本没有改变任何东西。我检查了我的附加依赖项，没有出现任何拼写错误:

sfml-main-d.lib;sfml-audio-d.lib;sfml-system-d.lib;sfml-window-d.lib;sfml-graphics-d.lib;

我的发布依赖项:

sfml-system.lib;sfml-window.lib;sfml-graphics.lib;sfml-audio.lib;kernel32.lib;user32.lib;gdi32.lib;winspool.lib;comdlg32.lib;advapi32.lib ;shell32.lib;ole32.lib;oleaut32.lib;uuid.lib;odbc32.lib;odbccp32.lib;

再次声明，我是 C++ 的新手，所以我可能会做一些非常愚蠢的事情。我不认为我的源代码与它有任何关系，但是有人建议我添加

#pragma comment(lib, "sfml-main-d.lib")
#pragma comment(lib, "sfml-system-d.lib")
#pragma comment(lib, "sfml-window-d.lib")
#pragma comment(lib, "sfml-graphics-d.lib")

在我的主要方法之上，所以我做到了。

有人知道我做错了什么吗？

谢谢

我不能添加评论，但是你可以将链接器设置为 /VERBOSE 这样你就可以看到链接器找到了哪些库以及 .lib'你指定的是否真的被链接进来了？

设置在C++ > Linker > Progress I think
