 Hi, I have problem in my little test program:

 {{{
         std::string decoded = "this is standart string with
 username=\"myusername\" etc. ";

         static const boost::regex regUsername("username=\"(.*)\"");
         boost::cmatch matches;
         std::string::const_iterator begin;
         begin = decoded.begin();

         while(boost::regex_search(begin, decoded.end(), matches,
 regUsername)){
                 std::string text(matches[1].first, matches[1].second);
                 std::cout << "OUTPUT: " << text << std::endl;
                 begin = matches[1].second;
         }
 }}}

 compile error:
