遇到致命错误：找不到'type_traits'文件#include< type_traits&gt ;,而构建clang示例 [英] Getting fatal error: 'type_traits' file not found #include <type_traits>, while building clang example

问题描述

我正在尝试建立来自clang的PrintFunctionNames 示例。
但是我得到以下错误：

I am trying to build the PrintFunctionNames example from clang. However I get the following error:

[mac-osx:clang/examples/PrintFunctionNames] osx% clang++ -std=c++0x PrintFunctionNames.cpp

编辑1：

在进行Alex建议的更改时，我开始遇到标题问题。

on making the changes suggested by Alex, I start getting header issues. On fixing it via includes, same error is thrown again

推荐答案

OS X（macOS）您可以安装多个Xcode，并为不同的平台编译。
您应该使用 -isysroot 选项明确指定要构建哪个SDK。

OS X (macOS) has a bit different approach. You can have several Xcode installed and you compile for different platforms. You should use -isysroot option to explicitly specify against which SDK to build.

以下命令应该做的

clang++ -std=c++0x PrintFunctionNames.cpp -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk

安装这些SDK并更改 isysroot 的值以与您的设置相对应。

Otherwise, please check which SDKs are installed and change the value of isysroot to correspond to your setup.
