如何解决“没有手动输入gcc”？ [英] How to fix "No manual entry for gcc"?

问题描述

我以某种方式丢失了gcc和g ++的手册页。我不确定在哪里寻找什么。我很确定这个手册页以前用过。在我使用大致相同的设置的工作中，它也适用于我的Mac。这可能是酿造的问题吗？或者它是XCode命令行工具中的错误？

I somehow lost the man pages for gcc and g++. I'm not sure where/what to look for. I'm pretty sure the man pages used to work some time ago. It also works on my Mac at work where I use roughly the same setup. Could it be a problem with brew? Or is it a bug in the XCode Command Line Tools?

更新：我只是试图重新安装XCode命令行工具。

Update: I just tried to re-install the XCode Command Line Tools. No luck.

~
✓  man gcc
No manual entry for gcc

~
✗  which gcc
/usr/bin/gcc

~
✓  gcc --version

推荐答案

gcc不再由Xcode安装，它确实安装了clang并将其称为gcc

gcc isn't installed anymore by Xcode, it really installs clang and calls it gcc

usxxplayegm1:~ grady$ which gcc
/usr/bin/gcc

usxxplayegm1:~ grady$ /usr/bin/gcc --version

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

你需要 man clang

我认为这是一个符号链接，但 ls -l <​​/ code>不会将其列为符号链接，因此无论是硬链接还是其他类型的欺骗。

I thought it was a symlink, but ls -l doesn't list it as a symlink, so either it is a hard link or some other sort of trickery.
