我可以使用C ++ 11与Xcode吗？

问题描述

我正在考虑在一些跨平台项目（Windows + Mac）中使用一些C ++ 11功能（例如 auto ）。在Windows上，Visual Studio支持即将到来的C ++ 11标准的一部分，这将允许我简化代码库的一部分，所以我很想开始使用这些功能。

但据我所知，目前的XCode版本（3.2.4 + GCC 4.2）不支持任何C ++ 11功能。我可以升级GCC版本或CLang版本吗？

解决方案

Xcode 4.2终于开始了添加对C ++ 0X的支持：

1. 在项目构建设置屏幕中，打开所有选项。 >




2. 在构建选项部分中，将编译器设置为Apple LLVM compiler 3.0。




3. 向下滚动到Apple LLVM Compiler 3.0 - 语言部分，并将C ++语言方言设置为C ++ 0X，将C ++标准库设置为libc ++。

std :: move（），move constructor和R-Value引用已知可以正常工作，我正在测试std :: thread和std :: atomic。

I am considering the use of some C++11 features (like auto for instance) in some cross-platform projects (Windows+Mac). On Windows, Visual Studio supports parts of the upcoming C++11 standard that would allow me to simplify parts of the code base so naturally I would be interested in starting to use these features.

But as far as I am aware, the current XCode version (3.2.4 + GCC 4.2) does not support any C++11 features at all. Can I upgrade the GCC version or the CLang version somehow? Or should I just bite my tongue and wait for Apple to package a new version sometime in the future?

解决方案

Xcode 4.2 had finally added support for C++0X:

1. In the project build settings screen, switch on "All" options.

2. In the "Build Options" section, set compiler to "Apple LLVM compiler 3.0".

3. Scroll down to "Apple LLVM Compiler 3.0 - Language" section and set "C++ Language Dialect" to "C++0X" and "C++ Standard Library" to "libc++".

The std::move(), move constructor and R-Value reference are known to work as expected, and I'm testing on the std::thread and std::atomic.
