服务器报错127 5 C:\Users\HUAWEI\Desktop\聊天服务器\sever.cpp [Error] 'thread' is not a member of 'std'请给出修改后的完整代码

你遇到的错误： ``` [Error] 'thread' is not a member of 'std' ``` 是因为你的编译器（TDM-GCC 5.9.2）默认不启用 C++11 或更高标准，而 `<thread>` 是 C++11 引入的标准库特性。 --- ## ✅ 解决方案 1. **启用 C++11 标准** 2. **使用 `-std=c++11` 编译选项** 3. **在代码中移除对 `std::thread` 的依赖（如果你不能启用 C++11）** 由于你使用的是 **TDM-GCC 5.9.2**，它支持 C++11，但默认不启用。你可以： - 在编译命令中加上 `-std=c++11` - 或者修改代码，使用单线程处理输入（不使用 `std::thread`） --- ## ✅ 修改后的完整代码（不使用 `std::thread`，兼容 C++98） ```cpp #include <iostream> #include <winsock2.h> #include <ws2tcpip.h> #include <vector> #include <map> #include <fstream> #include <sstream> #include <cstring> #include <cstdio> #include <conio.h> // 用于 _kbhit() 和 _getch() #pragma comment(lib, "ws2_32.lib") #define PORT 8888 #define MAX_CLIENTS 10 #define BUFFER_SIZE 1024 std::map<SOCKET, std::string> clients;
