C2977: 'std::tuple' : too many template arguments (MSVC11)

Question

I\'m trying to build googletest with Visual C++ 11, but following code causes an error

template 

        

Answer 1

In Visual Studio 2012 (VC11) _VARIADIC_MAX is by default defined as 5 in header :

#if !defined(_VARIADIC_MAX)
 #define _VARIADIC_MAX  5

#elif _VARIADIC_MAX < 5 || 10 < _VARIADIC_MAX
 #error _VARIADIC_MAX must be between 5 and 10, inclusive
#endif /* !defined(_VARIADIC_MAX) */

if you have multiple VC11 projects include in a solution, it is better to set the macro to all by

1) Shift click to select all C++ projects in your solution

2) Properties, C/C++, Preprocessor, All Configurations All Platforms, Preprocessor Definitions,

3) add before a row

_VARIADIC_MAX=10;

You can change 10 to any number in 6~10.
