Question

我正在尝试使用mingw32 for Linux编译this。

但是，我收到以下错误和警告：

如何解决有关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compiling with Visual Studio 2010 or later makes the application incompatible with the Windows 2000 target OS。因此，即使它以这种方式构建，二进制文件也不会执行。

正如您可以猜到的那样，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。

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’表示您缺少#include <stdio.h>

Winsock2.h：没有这样的文件或目录
