找不到 macOS 'wchar.h' 文件 [英] macOS 'wchar.h' File Not Found

问题描述

在使用 XCode 6.0.1 的 OS X 10.9.5 下，当我尝试从终端运行 make 时遇到以下问题:

Under OS X 10.9.5 using XCode 6.0.1 I am running into the following issue when I try to run make from the terminal:

fatal error: 'wchar.h' file not found

这个问题在最近升级到 Mavericks 之前没有发生.

This issue was not happening prior to a recent upgrade to Mavericks.

推荐答案

首先确保安装了最新的 XCode.接下来，我们需要安装/修复/更新命令行工具.为此，运行

First ensure that the latest XCode is installed. Next, we need to install/fix/update Command Line Tools. To do so, run

xcode-select --install

以前，XCode 期望它的活动开发者目录位于

Previously, XCode expected it's active developer directory to be located at

/Applications/Xcode.app/Contents/Developer/

但安装了最新的命令行工具

but the latest Command Line Tools is installed to

/Library/Developer/CommandLineTools/

所以我们需要切换 XCode 的位置.为此，运行

so we need to switch where XCode is looking. To do so, run

sudo xcode-select --switch /Library/Developer/CommandLineTools/

应该就是这样.这些步骤为我自己和两个同事解决了这个问题.

And that should be it. These steps solved the issue for myself and two coworkers.
