錯誤:: sregex_token_iterator

Question

我想搜索正則表達式並使用顏色打印它。我用boost :: sregex_token_iterator來做到這一點。這是我的代碼

boost::regex re("ab."); 
    string s=""; 
    string buf; 
    string infile("retest.txt"); 
    //string color="green"; 
    ifstream in(infile.c_str()); 
    int lcount=0; 
    while (getline(in,buf)) 
    { 
     boost::sregex_token_iterator p(buf.begin(), buf.end(), re, 0); 
     boost::sregex_token_iterator end; 
     lcount++; 
     cout <<"line : "<<lcount<<endl; 
     for (;p != end;++p) 
     { 
      string m(p->first, p->second); 
      cout<< m <<endl; 
      //cout <<*(p->first)<<endl; 
      //cout <<*(p->second)<<endl; 
      //unsigned int pos = buf.find(m); 
      buf = buf.insert(p->first,"\e[0;32m"); 
      buf = buf.insert(p->second+m.length()+7,"\e[0m"); 
     } 
     cout<<"\n"; 
     s.append(buf); 
     s.append("\n"); 
    } 
    in.close(); 
    cout <<"s is: "<<s<<endl; 
    return 0; 
    } 

，但我得到這個錯誤：

我知道的p->first的類型不是其插入功能接受一個。但我不知道如何將這些轉換爲對方。

Answer 1

問題似乎是boost配置爲使用不同版本的編譯器，而不是您當前使用的版本。

您可以添加編譯它的細節嗎？

Answer 2

這個問題可能是您使用std::string::insert。我無法看到插入（迭代器，字符串）版本之間的許多重載。

你可能想通過顯式聲明字符數組的長度來調用所需的版本：風格

void insert (iterator p, size_t n, char c)
