Build Fail：找不到winsock2.h文件

Question

添加了#define _WINSOCKAPI_，但构建失败了。

/*
 * $PostgreSQL: pgsql/src/include/port/win32/sys/socket.h,v 1.7 2006/10/04 00:30:10 momjian Exp $
 */
#ifndef WIN32_SYS_SOCKET_H
#define WIN32_SYS_SOCKET_H

/*
 * Unfortunately, <wingdi.h> of VC++ also defines ERROR.
 * To avoid the conflict, we include <windows.h> here and undefine ERROR
 * immediately.
 *
 * Note: Don't include <wingdi.h> directly.  It causes compile errors.
 */
#define _WINSOCKAPI_    //added this line but no help
#include <winsock2.h>
#include <ws2tcpip.h>
#include <windows.h>

#undef ERROR
#undef small

/* Restore old ERROR value */
#ifdef PGERROR
#define ERROR PGERROR
#endif

/*
 * we can't use the windows gai_strerror{AW} functions because
 * they are defined inline in the MS header files. So we'll use our
 * own
 */
#undef gai_strerror

#endif   /* WIN32_SYS_SOCKET_H */

Answer 1

您正尝试在绝对不是Windows的平台上编译特定于Windows的头文件。我无法想象你对此的期望;不管它是什么，但它没有。

Answer 2

尝试使用

#ifndef __APPLE__ ... #endif

然后，检查其他编译错误并包含苹果特定的套接字文件，这些文件也可以在BSD套接字下工作。
