Winsock2.h：沒有這樣的文件或目錄

Question

我想用Linux的mingw32編譯this。

不過，我得到以下錯誤和警告：

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

如何解決有關Winsock2.h錯誤？我確實設法在Windows 7上使用Visual Studio 2013進行編譯，這將是一個可接受的解決方案，但compiling with Visual Studio 2010 or later makes the application incompatible with the Windows 2000 target OS。所以即使它以這種方式構建，二進制文件也不會執行。

正如你可以猜到它的名字，winsock2.h直接關係到Windows實現的TCP/IP套接字，並且只存在於Windows系統上。

在Windows和Linux之間可能很難兼容include。恕我直言，你應該：

• 從源中刪除#include <winsock32.h>爲Linux編譯或更好的寫：

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

• 附加（最終在#else部分）失蹤頭

目前， warning: incompatible implicit declaration of built-in function ‘printf’顯示你缺少一個#include <stdio.h>
