Hi,
I using boost::bind() to create thread. But, I got errors at:
threadGroup.create_thread(boost::bind(&lab1::Server::Run, server));
Any help is really appreciated. 
Code is as follows: ---------------------------------------------
class Server {public:  // The constructor takes a port number and prepares to receive HTTP  // requests from clients on that port.  explicit Server(int port);
  // Closes the connection.  ~Server();
  //   void Run();  //Server(Server&);private:  // 'listening' socket used to establish HTTP connections  int listen_fd_;
  // Non-copyable, non-assignable  Server(Server&);  Server& operator=(Server&);}; 

int main(int argc, char *argv[]) {  if (argc != 2) {    std::cout << "Usage: lab1 <port>" << std::endl;    return 1;  }
// Convert the port from a string to an integer.  int port_number;  std::istringstream port_stream(argv[1]); // argv[1] is port number,   port_stream >> port_number;
  // Convert the thread number from a string to an integer.  int thread_number;  std::istringstream thread_stream(argv[2]); // argv[1] is port number,   thread_stream >> thread_number;  lab1::Server server(port_number);
boost::thread_group threadGroup;
for(int i=0;i<thread_number;i++)  {
     threadGroup.create_thread(boost::bind(&lab1::Server::Run, server));  }threadGroup.join_all();      return 0;}
