After install Xcode, where is clang?
提问by mko
I installed the newest version of Xcode.
我安装了最新版本的 Xcode。
gcc,cc,clang, either of them exist in the terminal.
gcc,cc,clang，它们中的任何一个都存在于终端中。
How can I find the c compiler in the terminal that Xcode use?
如何在 Xcode 使用的终端中找到 c 编译器？
回答by hamstergene
Type in Terminal
输入终端
xcodebuild -find make
xcodebuild -find gcc
xcodebuild -find g++
xcodebuild -find clang
xcodebuild -find clang++
Each command prints full path to the corresponding tool. They are the ones that are used by Xcode.
每个命令都会打印到相应工具的完整路径。它们是 Xcode 使用的那些。
You can also install Xcode Command Line Tools which will place tools and libs under standard Unix locations (/usr/bin, /usr/includeetc.) if you want to be able to just type makeor gccwithout any paths. Note that these tools will be unrelated to the ones that Xcode application uses and may be of different versions.
您还可以安装Xcode的命令行工具，这将使工具和库在标准的Unix位置（/usr/bin，/usr/include如果你想能够只是类型等），make或gcc没有任何路径。请注意，这些工具将与 Xcode 应用程序使用的工具无关，并且可能具有不同的版本。

Such commands have been made into a separate "command-line tools" package as of Xcode 4.3 or thereabouts
从 Xcode 4.3 开始，此类命令已被制作成一个单独的“命令行工具”包
They have been moved into the Xcode.appbundle as part of making Xcode a more standard App Store install. The separate CLI tools is also useful for projects like Homebrewwhich have no need for the full Xcode download
Xcode.app作为使 Xcode 成为更标准的 App Store 安装的一部分，它们已被移入捆绑包中。单独的 CLI 工具对于像 Homebrew这样不需要完整 Xcode 下载的项目也很有用
To install (from here):
安装（从这里）：

- Go to Preferences

It seems to have moved: jarmac:~ jar$ xcodebuild -find clang /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
它似乎已经移动：jarmac:~ jar$ xcodebuild -find clang /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang

It's in Xcode app bundle:
它在 Xcode 应用程序包中：
/Applications/Xcode.app/Contents/Developer/usr/bin/
