问题

我想在类定义中分配值，该类定义位于类声明cpp的单独头文件中。

在编译时，我收到了这些错误消息：

error: ‘const std::map<unsigned int, std::basic_string<char> > bob::mRegexes’ is not a static member of ‘class bob’const std::map<uint,std::string> bob::mRegexes = {
                                   ^
error: ‘const std::map<unsigned int, std::basic_string<char> > bob::mResponses’ is not a  static member of ‘class bob’ const std::map<uint,std::string> bob::mResponses  = {

这两个都绝对令人生气，因为我不明白为什么编译器忽略typedef为std::string我觉得我在这里遗漏了一些东西，但我不是确定为什么bob.h文件看到的参数与bob.cpp不同。

bob.h

#ifndef BOB_H
#define BOB_H
#include <iostream>
#include <string>
#include <boost/regex.hpp>
#include <map>


typedef unsigned int uint;

// This was first to go when I started having problems.
/*using std::string;*/                                                                                                                                                                         
using std::map;
// boost::regex > c++11::regex (gcc doesn't follow standards).
using boost::regex;

class bob
{
  enum respond_to{
    QUESTION,
    YELL,
    NAME,
    DEFAULT,
    LENGTH
  };

public:
  static const respond_to mResponseTypes;
  static const map<uint,std::string> mRegexes;
  static const map<uint,std::string> mResponses;

  static std::string hey(std::string sentence);
  static const std::string* evaluate (const std::string& sentence);
  static const std::string* getResponse(const std::string& sentence, const respond_to& type) noexcept(true);
};
#endif

bob.cpp

#include "bob.h"

const std::map<uint,std::string> bob::mRegexes = {
  {QUESTION, "[a-z]+\\?"},
  {YELL,"[A-Z]+"}
};

const std::map<uint,std::string> bob::mResponses  = {
  {QUESTION,"Sure"},
  {YELL,"Whoah, chill out!"},
  {DEFAULT,"Whatever."}
};
