However, real projects have external dependencies, which is where it gets complicated. This second step is necessary because the new C++11 features depend on library support in the standard library, and the default standard library ‘libstdc++’ does not implement them, but ‘libc++’ does.įor a standalone project, all is well now. Select ‘ libc++’ as the standard library by setting “C++ Standard Library” to “libc++ (LLVM C++ standard library with C++11 support)” in the same section.Enable the C++11 language features in the “build settings” pane. Under “Apple LLVM compiler 4.1 – Language” (select “All” instead of “Basic” settings first), set “C++ Language Dialect” to “C++11 ”.Here is how it works with Xcode 4.5 under OS X 10.8 Mountain Lion. Visual Studio 2010 already supports some of these features out of the box, and Visual Studio 2012 implements even more (detailed list of features implemented by different compilers). The new C++11 standard includes many language and library features that make programming in C++ more enjoyable, such as lambdas, the auto keyword and smart pointers (in the STL).
