我最近开始学习SFML,但是当我进入网络部分时,我总是遇到很多错误:

我正在使用CodeBlocks,编译器参数是:
mingw32-g++.exe -LC:\Users\Justin\AppData\Roaming\CodeBlocks\SFML-2.2\lib -o "bin\Release\SFML Test.exe" obj\Release\main.o -s -lsfml-graphics -lsfml-window -lsfml-system
这只发生在我使用网络功能时,没有别的(但我没有尝试过音频)。
提前致谢。
编辑:这是我的代码:
#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include <SFML/Network.hpp>
using namespace sf;
#include <iostream>
#include <string>
#define cout std::cout
#define endl std::endl
int main(){
IpAddress ip = IpAddress::getLocalAddress();
TcpSocket socket;
char connectionType, mode;
char buffer[2000];
std::size_t recieved;
std::string text = "Connected to: ";
cout << "Enter (s) for server; Enter (c) for client: ";
std::cin >> connectionType;
if(connectionType == 's'){
TcpListener listener;
listener.listen(123456);
listener.accept(socket);
text += "Server";
}else if(connectionType == 'c'){
socket.connect(ip, 123456);
text += "Client";
}else{
cout << "ERROR: Wrong Connection Type";
}
socket.send(text.c_str(), text.length());
socket.receive(buffer, sizeof(buffer), recieved);
cout << buffer << endl;
system("pause");
}
答案 0 :(得分:1)
与网络模块链接:
