I want to compile C++ code on MacOS X, using the g++ compiler. How do I install it?

推荐答案

这是Apple的XCode工具包附带的编译器。他们已经黑了一点，但基本上只是g ++。

That's the compiler that comes with Apple's XCode tools package. They've hacked on it a little, but basically it's just g++.

你可以免费下载XCode（好吧，大多数情况下，你必须注册成为一个ADC成员，但这是免费的）在这里： http://developer.apple.com/technology/xcode.html

You can download XCode for free (well, mostly, you do have to sign up to become an ADC member, but that's free too) here: http://developer.apple.com/technology/xcode.html

编辑2013-01-25：这个答案在三年前是正确的。我不知道现在是否正确。虽然XCode工具仍然有一个命令行C ++编译器，我相信最近版本的OS X（我认为10.7和更高版本）已切换到 clang / llvm （主要是因为苹果想要开源的所有好处，而不需要贡献回来，ang是BSD许可）。其次，我相信自从苹果开始推广App Store以获得一切之后，获得XCode的程序已经改变。

Edit 2013-01-25: This answer was correct three years ago. I'm not so sure it's correct now. While XCode tools still has a command-line C++ compiler, I believe recent versions of OS X (I think 10.7 and later) have switched to clang/llvm (mostly because Apple wants all the benefits of Open Source without having to contribute back and clang is BSD licensed). Secondly, I believe the procedure for getting XCode has changed since Apple started promoting the App Store as the way to get everything.
