gtest编译出错： 编译时，error C2977 "std::tuple" too many template arguments问题的解决办法

1. 编译时，error C2977 "std::tuple" too many template arguments问题的解决办法

网文http://www.cnblogs.com/fresky/articles/2455058.html中的方案如下：

打开 c:\program files (x86)\Microsoft Visual Studio 11.0\VC\include\xstddef，把 _VARIADIC_MAX定义成10。

这个方案一方面需要Administrator，其实是需要System权限才能修改Windows 8中的System文件，另一方面，会对所有的C/C++代码造成影响

其实，更简单的方法是打开“解决方案资源管理器”，右键打开项目“属性”，在C/C++ --> “预处理器”--> “预处理定义”中增加以下行即可：

_VARIADIC_MAX=10

坑爹吧？

上面的问题是vc的tr1/tuple引起的，后来高手指点下知道gtest是有一个宏来控制这个东东的，，，

//   GTEST_HAS_TR1_TUPLE      - Define it to 1/0 to indicate tr1::tuple
//                              is/isn't available.
//   GTEST_HAS_SEH            - Define it to 1/0 to indicate whether the
//                              compiler supports Microsoft's "Structured
//                              Exception Handling".
//   GTEST_HAS_STREAM_REDIRECTION
//                            - Define it to 1/0 to indicate whether the
//                              platform supports I/O stream redirection using
//                              dup() and dup2().
//   GTEST_USE_OWN_TR1_TUPLE  - Define it to 1/0 to indicate whether Google
//                              Test's own tr1 tuple implementation should be
//                              used.  Unused when the user sets
//                              GTEST_HAS_TR1_TUPLE to 0.

// Determines whether Google Test can use tr1/tuple.  You can define

// this macro to 0 to prevent Google Test from using tuple (any

// feature depending on tuple with be disabled in this mode).

#ifndef GTEST_HAS_TR1_TUPLE

// The user didn't tell us not to do it, so we assume it's OK.

# define GTEST_HAS_TR1_TUPLE 1

#endif  // GTEST_HAS_TR1_TUPLE

// Determines whether Google Test's own tr1 tuple implementation

// should be used.

#ifndef GTEST_USE_OWN_TR1_TUPLE

// The user didn't tell us, so we need to figure it out.
