问题:

How can I use the latest C++ 11 features in Clang? What (sub)set of features is supported?

回答1:

You will need clang 3.3 to use the most relevant feature set from C++ 11. Read C++ Support in Clang for the complete list of up-to-date supported features. Clang 3.3 is claimed to be C++11 feature complete.

Clang's command line is gcc-compatible so you have to enable C++11 support via the followinf command-line switch

-std=c++11

There is also a bunch of post-C++11 features (like decltype(auto), member initializers and aggregates) that are supported by Clang 3.3. Use this command line switch to enable them

-std=c++1y

Here is the always up to date list of features supported by clang:

To activate C++11, you have to add -std=c++11 in your clang calls, like for gcc. If you use an IDE that is clang-aware or gcc-aware, there is a specific project settings option available to do that.
