在我的优胜美地系统上，'/ usr'中的'llvm-gcc-4.2'是做什么的？ [英] What is 'llvm-gcc-4.2' doing in '/usr' on my Yosemite system?

问题描述

在我的（已迁移的）优胜美地系统上的 / usr 中，我有一些旧的目录（2011-12）对我来说不合适：

  /usr/llvm-gcc-4.2 
 /usr/include/gcc/darwin/4.2 
  

这些是什么？他们是最新的吗？我可以摆脱他们吗？我已经安装了最新的Xcode和命令行工具，如果这很重要的话。

解决方案

它们是Xcode命令行工具， code> llvm-gcc 不再使用，所以看起来它们还没有从以前的版本中清除过。

<我认为最好让他们独处，因为我不明白他们会如何引发问题;然而，如果他们似乎造成了问题，那么 mv 他们到xxx-DELETE_ME，看看你几个星期的时间。如果一切正常，然后删除它们。

In /usr on my (migrated) Yosemite system I have some old (2011-12) directories that look out of place to me:

/usr/llvm-gcc-4.2
/usr/include/gcc/darwin/4.2

What are these? Are they current; can I get rid of them? I have the latest Xcode and command line tools installed, if that matters.

解决方案

They are the Xcode command line tools, but llvm-gcc is no longer used, so it looks like they haven't been cleaned-up from a previous version.

I think it's best to leave them alone as I cannot see how they will cause an issue; however if they do seem to be causing issues, then mv them to xxx-DELETE_ME and see where you are in a few weeks time. If everything is OK then delete them then.
