无法编译boost :: asio :: basic_datagram_socket <boost::asio::ip::udp> :: basic_datagram_socket（）

Question

I'm trying to make a proper udpServer class that would be the parents of my udpServerBoost. (the udpServer is not implement atm)

And since i try to change my class constructor for let it create the io_service by itself I got an error when i'm compiling my src

src/UdpServerBoost.cpp: In constructor ‘UdpServerBoost::UdpServerBoost()’:

I already compiled the boost library with g++ and it worked. So I know that the problem doesn't come from it :(

So this is my source ! Thank's for reading ^^

Have a nice day

This is my udpServerBoost.cpp

UdpServerBoost::UdpServerBoost()
{
    boost::asio::io_service io_service;
    socket_ = udp::socket(&io_service, udp::endpoint(udp::v4(), 1300));

    memset(&recv_buffer_, 0, 2048);
    clientList_ = std::vector<ClientBoost>();
    startReceive();
    io_service.run();
}

And the .hpp

class UdpServerBoost
{
  public:
    UdpServerBoost();
    ~UdpServerBoost() {};

  private:
    void startReceive();

    void handleReceive(const boost::system::error_code &error,
                       std::size_t bytes_transferred);

    void handleSend(boost::shared_ptr<std::string> /*message*/,
                    const boost::system::error_code & /*error*/,
                    std::size_t /*bytes_transferred*/);

    ClientBoost getClient();

    void treatMessage(std::string mess);
    void sendToClient(ClientBoost client, std::string mess);

    std::vector<ClientBoost> clientList_;
    udp::socket socket_;
    udp::endpoint remote_endpoint_;
    boost::array<char, 2048> recv_buffer_;
};

Answer 1

You're default-constructing the socket. That's not allowed. You must at least provide a reference to its executor (io_service).

Try something like this:

class UdpServerBoost
{
  UdpServerBoost();

  boost::asio::io_service my_io_service_;
  udp::socket my_socket_;
};

UdpServerBoost::UdpServerBoost()
: my_io_service_()
, my_socket_(my_io_service_)
{
}
