only static const int type 可以被定義

You have to define your static member outside the class definition and provide the initailizer there. // In a header file (if it is in a header file in your case) class A {   private:         static const string RECTANGLE; }; // In one of the implementation files const string A::RECTANGLE = "rectangle"; The syntax you were originally trying to use (initializer inside class definition) is only allowed with integral and enum types.
