Is there a preprocessor directive for detecting C++11 Standard library?
c++, c++11, c-preprocessor, libc++
Solution
Testing for features is an active research direction for the Standard Committee going towards the next C++14 Standard (and beyond that). There is a Study Group 10 with its own freely accessible mailinglist where current development is being discussed. For the next meeting, this N3694 working paper has been submitted.
Problem
Is it possible to determine if C++ standard library has C++11 support using a preprocessor directive? I'm currently working on a project which uses the C++11 language dialect, but with the a C++ standard library without C++11 support (I need this to be able to link with non C++11 libraries). I'm aware of that I can test of C++11 support using the `#if __cplusplus >= 201103L`, but in my case this will evaluate to true. I need to know about the C++ standard library support for C++11.
