我试图创建一个合适的udpServer类,它将成为我的udpServerBoost的父级。 (udpServer没有实现atm)
因为我试图改变我的类构造函数让它自己创建io_service我在编译我的src时出错了

我已经使用g ++编译了boost库,但它确实有效。所以我知道问题并非来自它:(
所以这是我的来源!感谢阅读^^
度过愉快的一天
这是我的 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();
}
.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_;
};
答案 0 :(得分:2)
你是默认构造套接字。这是不允许的。您必须至少提供对其执行者(io_service)的引用。
尝试这样的事情:
class UdpServerBoost
{
UdpServerBoost();
boost::asio::io_service my_io_service_;
udp::socket my_socket_;
};
UdpServerBoost::UdpServerBoost()
: my_io_service_()
, my_socket_(my_io_service_)
{
}
