How can I find out if I have Xcode commandline tools installed?
提问by P i
I need to use gdb.

-bash: gdb: command not found
ps-MacBook-Air:AcoustoExport pi$ sudo find / -iname "*gdb*"

和：
ps-MacBook-Air:AcoustoExport pi$ ls -la /usr/local/share/gdb
lrwxr-xr-x 1 pi admin 30 14 Jan 22:01 gdb -> ../Cellar/isl/0.12.1/share/gdb
Not quite sure what to make this, clearly it is something installed by homebrew. I don't know why it's there, I don't know whether I could use it instead. It isn't in the search path.
不太确定要做什么，显然这是自制软件安装的东西。我不知道它为什么在那里，我不知道我是否可以用它代替。它不在搜索路径中。
So I figure I need Xcode commandline tools.
所以我想我需要 Xcode 命令行工具。
Xcode is not currently available from the Software Update server

Thanks to the folks on Freenode's #macdev, here is some information:
感谢 Freenode 的 #macdev 上的人们，这里有一些信息：
In the old days before Xcode was on the app-store, it included commandline tools.
在 Xcode 出现在应用商店之前的过去，它包含命令行工具。
Now you get it from the store, and with this new mechanism it can't install extra things outside of the Xcode.app, so you have to manually do it yourself, by:
现在您可以从商店获取它，并且通过这种新机制，它无法在 Xcode.app 之外安装额外的东西，因此您必须自己手动完成，通过以下方式：
xcode-select --install
On Xcode 4.x you can check to see if they are installed from within the Xcode UI:
在 Xcode 4.x 上，您可以检查它们是否是从 Xcode UI 中安装的：
On Xcode 5.x it is now here:
在 Xcode 5.x 上，它现在在这里：
My problem of finding gcc/gdb is that they have been superseded by clang/lldb: GDB missing in OS X v10.9 (Mavericks)
我找到 gcc/gdb 的问题是它们已被 clang/lldb 取代：OS X v10.9 (Mavericks) 中缺少 GDB
Also note that Xcode contains compiler and debugger, so one of the things installing commandline tools will do is symlink or modify $PATH. It also downloads certain things like git.
另请注意，Xcode 包含编译器和调试器，因此安装命令行工具要做的一件事是符号链接或修改 $PATH。它还下载某些东西，比如 git。
