Winsock2.h：没有这样的文件或目录

Question

我正在尝试使用mingw32 for Linux编译它 。

但是，我收到以下错误和警告：

# i586-mingw32msvc-gcc ms04-020.c -lws2_32 -o ms04-020.exe

如何修复Winsock2.h的错误？ 我确实设法在Windows 7上使用Visual Studio 2013进行编译，这是一个可接受的解决方案，但是使用Visual Studio 2010或更高版本进行编译会使应用程序与Windows 2000目标操作系统不兼容 。 因此，即使它以这种方式构建，二进制文件也不会执行。

正如你可以猜到的那样， winsock2.h与Windows的TCP / IP套接字实现直接相关，并且只存在于Windows系统上。

在Windows和Linux之间可能很难完全兼容include 。 恕我直言，你应该：

• 从源代码中删除#include <winsock32.h>以进行Linux编译或更好地编写：

   #ifdef _WIN32 #include <Winsock2.h> #endif 

• 添加（最终在#else部分中）缺少的标题

目前， warning: incompatible implicit declaration of built-in function 'printf'表明你缺少#include <stdio.h>
