找不到stdio.h [英] Cannot find stdio.h

问题描述

我正在使用macOS.

I am using macOS.

我正在尝试构建mozilla-central的代码.

I am trying to build the code of mozilla-central.

运行命令./mach build时，编译在编译步骤失败.以下是相关的堆栈跟踪:

While running the command ./mach build, the build fails at the compile step. Here are the relevant stack traces:

根据我的说法，根本原因是:

According to me, the root cause is:

/usr/local/Cellar/llvm/6.0.1/include/c++/v1/stdio.h:108:15: fatal error: 'stdio.h' file not found, err: true

在线列出的解决方案是使用以下命令安装xcode命令行工具:

The solution listed online was to install xcode command line tools using:

xcode-select --install

我已经做到了.

推荐答案

根本原因是由于缺少/usr/include目录.

The root reason is due to a missing /usr/include directory.

有时，安装命令行工具(xcode-select --install)不会自动添加它.

Installing command-line tools (xcode-select --install), sometimes, will not automatically add it.

链接显示了正确的方法: 安装命令行工具后 在以下位置安装软件包:

The Link shows the correct way: After installing command-line tools Install the package at:

# run this in Terminal
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg

之后，

您应该具有包含头文件的目录/usr/include

you should have a directory /usr/include with header files
