在Visual Studio 2012中进行Googletesting
我正在尝试开始unit testing。 我下载了gtest的最新版本，并将其提取到A:\gtest作为指定的指示，我打开gtest.sln。 Visual Studio只允许我打开sln，如果我同意更新它。 然后当我尝试build立时，我得到一堆错误：

我做错了什么或VS2012这个问题？ 我没有附加到谷歌testing，并不反对使用不同的框架，如果它与VS更好的工作，我刚刚听到gtest的很好的东西。
VC ++ 2012不会（也不会）支持可变参数模板; 因此，它的标准库实现尝试使用预处理器生成的重载和专业化来伪造它们。 正如这篇博客文章所指出的，人造variables模板参数的数量默认为5–问题在于gtest正试图用多达10个模板参数实例化std::tuple<> 。
正如博客文章所说，您可以在项目范围内定义_VARIADIC_MAXmacros以支持最多10个参数; 您可能希望通过项目的预处理器定义设置来完成此操作，但重要的是要确保每个TU在包含任何stdlib标头（直接或间接）之前对其进行定义。
我没有使用_VARIADIC_MAXmacros修改VS2012元组实现，而是通过在包括gtest头文件的gtest项目和项目中定义以下两个macros来解决这个问题：
GTEST_HAS_TR1_TUPLE=0 GTEST_USE_OWN_TR1_TUPLE=1
将GTEST_HAS_TR1_TUPLE设置为0可防止gtest尝试从STL头中使用元组类，并将GTEST_USE_OWN_TR1_TUPLE设置为1将指示gtest使用自己的元组实现，而不是省略需要元组支持的function。 我个人更喜欢这个选项来调整STL的实现，这个解决scheme应该适用于其他有类似问题的编译器。
这在r675版本中是固定的。 请参阅https://code.google.com/p/googletest/source/detail?r=675
另外，在获得最新版本之前，请将GTEST_USE_OWN_TR1_TUPLE=0添加到您的预处理器定义中。
