C++ c++；与gtest和boost的命名空间冲突

如果我同时包括gtest/gtest.h和boost/math/distributions/poisson.hpp，我得到

如何防止这两个库名称空间发生冲突？

您是否尝试过切换包含的顺序？另一个头文件可能会处理得更优雅一些。

尝试使用

BOOST\u构建已定义的\u TR1\u元组。看起来boost和您的
std
库都在定义
std:：tr1:：tuple
，我看不出如何禁用
std
版本。查看boost头，但似乎需要定义
boost\u有\u TR1\u TUPLE
来告诉boost已经定义了
std:：TR1:：TUPLE

当我试图编译一个包含这两个标题的文件时，我遇到了与您类似的错误，然后当我在Microsoft Visual Studio 2010中定义了
BOOST\u HAS\u TR1\u TUPLE
以包含BOOST/math/distributions/fisher\u f.hpp>时，它们消失了，
我需要定义
BOOST\u NO\u 0X\u HDR\u TUPLE
以及
BOOST\u HAS\u TR1\u TUPLE
，使用gtest设置gtest\u HAS\u TR1\u TUPLE在gtest中为0。在我的情况下，h有帮助
不幸的是，更改顺序（从gtest/BOOST到BOOST/gtest会造成更大的混乱）。这取决于编译器版本和gtest版本。GTest也定义自己的元组，除非编译器是GCC4+。因此，在本例中，boost将使用gtest实现，这可能是您不想要的。但是您也可以通过将gtest_use_OWN_TR1_tuple设置为0来使用gtest中的boost元组。
