How to deal with noexcept in Visual Studio

May 16, 2023 by Tarik

Use a macro

#ifndef _MSC_VER
#define NOEXCEPT noexcept
#else
#define NOEXCEPT
#endif

And then define the function as

virtual const char* what() const NOEXCEPT override

You could also modify that to allow noexcept on later versions of VS by checking the value of _MSC_VER; for VS2012 the value is 1600.
