错误：分配给＆＃39; mapped_type＆＃39; （又名＆＃39; int（*）（）＆＃39;）来自不兼容的类型＆＃39; int（Rsh :: *）（*）＆＃39;

Question

我不明白为什么会出现这个错误..

所有需要的lib已包含在其他.h

中

我有一个Rsh.h：

class Rsh
{
    private:
        map<string, int(*)(const string &, FILE*)>  supportedCmds;

    public:
                            Rsh                     ();
                            ~Rsh                    ();
        void                setup                   ();
};

和Rsh.cpp：

void                Rsh::setup()
{
    // Fill up list of supported commands
    supportedCmds["cd"]         = &Rsh::ashCd;
    supportedCmds["ls"]         = &Rsh::ashLs;
    supportedCmds["pwd"]        = &Rsh::ashPwd;
    supportedCmds["history"]    = &Rsh::ashHistory;
    supportedCmds["exit"]       = NULL;
}

输出g ++消息是这样的：

src/Rsh.cpp:24:26: error: assigning to 'mapped_type' (aka 'int (*)(const
      std::__1::basic_string<char> &, __sFILE *)') from incompatible type 'int (Rsh::*)(const
      string &, FILE *)'
        supportedCmds["cd"]                     = &Rsh::ashCd;
                                                  ^~~~~~~~~~~

      string &, FILE *)'
        supportedCmds["ls"]                     = &Rsh::ashLs;
                                                  ^~~~~~~~~~~

      string &, FILE *)'
        supportedCmds["pwd"]            = &Rsh::ashPwd;
                                          ^~~~~~~~~~~~

      string &, FILE *)'
        supportedCmds["history"]        = &Rsh::ashHistory;
                                          ^~~~~~~~~~~~~~~~

有什么建议吗？

已修复：map<string, int(Rsh::*)(const string &, FILE*)> supportedCmds; 感谢@WhiZTiM
