thanks,
But, this time, I got strange errors :
I cannot find where my code is wrong.
Any help is really appreciated.

threadGroup.create_thread(boost::bind(&lab1::Server::Run, &server));

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;
}
