【问题描述】：
我安装了 Xcode 4.3.1。尽管SCNetwork.h 中需要包含，但我收到未知类型名称socklen_t 错误
#ifndef _SCNETWORK_H
#define _SCNETWORK_H
#include <Availability.h>
#include <sys/cdefs.h>
#include <sys/types.h>
#include <sys/socket.h> // required include
#include <CoreFoundation/CoreFoundation.h>
我是否缺少任何包含？
从终端：

【问题讨论】：
-
<sys/socket.h>应该包含正确定义socklen_t的必要标头，因此您的项目或构建配置或其他东西可能有问题。发布预处理器输出（通过 Product → Generate Output → Generate Preprocessed File 菜单选项）。 -
预处理文件未突出显示。
-
那又怎样？如果您需要帮助，请发布预处理器输出。
-
我的意思是，我不能点击它，因为它没有突出显示。还有其他方法可以查看该输出吗？
-
嗯，这很奇怪。我对 Xcode 4.2 没有任何问题（它的语法也突出了预处理器的输出）。也许尝试退出 Xcode、重新加载和重新预处理？
