constexpr not compiling in VC2013

Question

This constexpr code does not compiled in Visual Studio 2013 version 12.0.21005.1 REL

Is there a newer Visual Studio compiler that works with constexpr?

Answer 1

constexpr is not supported in Visual Studio 2013 RTM, see the compatibility table. This is not only true for the RTM version, but also for the Visual Studio Updates.

If you want to stick to Visual Studio 2013, you could download the Visual C++ Compiler November 2013 CTP which comes with some new features, see MSDN blog. Unfortunately Microsoft has no merger with the latest Visual Studio Update features and the CTP features and clearly states that they don't plan to do so.

If we want it all, we need to wait for Visual Studio 2015, see the MSDN blog about VS 2015 Preview.
