error while working with boost::sregex_token_iterator

I want to search for a regular expression and print it with a color. I used boost::sregex_token_iterator to do this. this is my code 

    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;
  }

but I get this error :

I know that the type of p->first is not the one which insert function accepts. but I don't know how to convert these to each other.

Point of style, always use preincrement (++lcount) unless you have a reason to use postincrement. – Alex Chamberlain
Have you snipped the error message? – Alex Chamberlain
@alex thanks for the tip . I'm new in c++ . what exactly "snip the error" means ? – vahidzolf
Did you copy and paste the entire error? It seems to be missing a bit. – Alex Chamberlain
oh yes . I snipped the error output . It's too long and I think the part that I've mentioned is the most important one. I got errors like this and each time I would came up with a solution but this time is a little bit different :) – vahidzolf

The issue might be your usage of std::string::insert. I can't see an insert(iterator, string) version among it's numerous overloads.

You might want to call desired version by explicitly stating length of char array:

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

The problem seems to be that boost is configured for use with a different version of the compiler rather than the one you are currently using.

Could you add the details of how you compiled it as well?
