1. 編譯時(shí)，error C2977 "std::tuple" too many template arguments問題的解決辦法
打開 c:\program files (x86)\Microsoft Visual Studio 11.0\VC\include\xstddef，把 _VARIADIC_MAX定義成10。
這個(gè)方案一方面需要Administrator，其實(shí)是需要System權(quán)限才能修改Windows 8中的System文件，另一方面，會(huì)對(duì)所有的C/C++代碼造成影響
其實(shí)，更簡(jiǎn)單的方法是打開“解決方案資源管理器”，右鍵打開項(xiàng)目“屬性”，在C/C++ --> “預(yù)處理器”--> “預(yù)處理定義”中增加以下行即可：
坑爹吧？

上面的問題是vc的tr1/tuple引起的，后來高手指點(diǎn)下知道gtest是有一個(gè)宏來控制這個(gè)東東的，，，
// 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
