未解析的外部符号“ std :: basic_string”

Question

I am trying to compile a project with Maven via the Visual C++ compiler and I keep getting linkage errors in regards to the std::basic_string class. 我正在尝试通过Visual C ++编译器使用Maven编译项目，而关于std :: basic_string类，我一直收到链接错误。 I ensured that I include the < string > header file into the corresponding c++ file. 我确保将<string>头文件包含在相应的c ++文件中。

Did I miss something or did I make a silly mistake??? 我错过了什么还是我犯了一个愚蠢的错误？？？ Please let me know where I went wrong. 请让我知道我哪里出错了。

[ERROR] Parsor.obj : error LNK2001: unresolved external symbol

"__declspec(dllimport) public:
    int __thiscall std::basic_string<
        char,
        struct std::char_traits<char>,
        class std::allocator<char> >::compare(
            class std::basic_string<
                char,
                struct std::char_traits<char>,
                class std::allocator<char> > const &) const"

Answer 1

It seems that the linker settings might be incorrect in your VC++. 看来在VC ++中，链接器设置可能不正确。 Try a simple program to test std::strig functionality 尝试一个简单的程序来测试std :: strig功能
