Constexpr Not Compiling in Vc2013

constexpr not compiling in VC2013

Microsoft publishes a C++11 compatibility table, under which constexpr is clearly marked as not being available in Visual Studio 2013.

The November 2013 CTP has it, though.

Why does adding constexpr make VS2013 reject this?

Despite the 2013 in the name, VS2013 does not purport to be a compiler targeting the C++11 standard (which was when constexpr was introduced).

The value of __cplusplus will be 201103L for a C++11 compiler.

So your compiler encounters a token it does not recognise, and issues a diagnostic.

As per this microsoft devblog, constexpr is one of the C++11 core language features that is not supported in VS 2013. And it is only partially supported in "Nov 2013 CTP."

C++11 constexpr compilation error

Visual Studio 2013 does not support all the C++11 features. In the same time it supports tiny part of C++14 features like std::make_unique for example.

constexpr is not supported on Visual Studio 2013.

Why I am getting this error: constexpr' is not valid here

Non-static data members cannot be declared as constexpr. Use

class myClass
{
    static constexpr int x = 4;
};

instead.
