man找不到与符号链接指向的源文件相关的手册页

[英]man does not find man pages associated with the source files pointed to by symbolic links

原文 2014-09-22 18:28:48 2 1 linux/ gcc/ osx-mavericks/ manpage/ ln

My hard drive recently crashed, so I took the opportunity to upgraded from Mac OS X 10.6.8 to 10.9.5 from a fresh install. 我的硬盘驱动器最近崩溃了，所以我借此机会从全新安装从Mac OS X 10.6.8升级到了10.9.5。 Mavericks comes with "gcc" Apple LLVM version 6.0 (clang-600.0.51). Mavericks随附了“ gcc” Apple LLVM 6.0版（clang-600.0.51）。 I want to use gcc-mp-4.8 that I downloaded from Macports. 我想使用从Macports下载的gcc-mp-4.8。

So I renamed /usr/bin/gcc to /usr/bin/gcc_clang_6.0 所以我将/ usr / bin / gcc重命名为/usr/bin/gcc_clang_6.0
In /opt/local/bin (where all the executables from Macports are installed), I created the symbolic link ... sudo ln -s gcc-mp-4.8 gcc 在/ opt / local / bin（安装了Macports的所有可执行文件）中，我创建了符号链接... sudo ln -s gcc-mp-4.8 gcc

I can compile using the command "gcc" and save myself the extra 7 key strokes (yay!). 我可以使用命令“ gcc”进行编译，并为自己节省了额外的7个按键（是！）。 However, if I want to look at "man gcc", man cannot find it. 但是，如果我要查看“ man gcc”，则man找不到它。 I would really like to be able to view the man page without having to type "man gcc-mp-4.8" 我真的很希望能够不必输入“ man gcc-mp-4.8”即可查看手册页

Is there a way to fix this? 有没有办法解决这个问题？

Thanks! 谢谢！

Previously, I did not understand how and where man pages are stored. 以前，我不了解手册页的存储方式和位置。 So for instance you can type man -w gcc-mp-4.8 , so to symbolically link them, I used sudo ln -s $(man -w gcc-mp-4.8) /opt/local/man/man1/gcc.1.gz . 因此，例如，您可以键入man -w gcc-mp-4.8 ，以便以符号方式链接它们，我使用了sudo ln -s $(man -w gcc-mp-4.8) /opt/local/man/man1/gcc.1.gz 。
