c ++命名空间与gtest和boost冲突

Question

如果我包括GTEST/gtest.h和升压/数学/发行/ poisson.hpp我得到

/opt/local/include/boost/tr1/tuple.hpp:63: error: ‘tuple’ is already declared in this scope
/opt/local/include/boost/tr1/tuple.hpp:67: error: ‘make_tuple’ is already declared in this scope

/opt/local/include/boost/tr1/tuple.hpp:73: error: ‘tuple_element’ is already declared in this scope

如何防止这两个库命名空间发生冲突？

Answer 1

尝试用已BOOST_HAS_TR1_TUPLE定义的构建.它看起来像boost和你的std库都在定义std::tr1::tuple,我看不到如何禁用该std版本.看看boost标题虽然看起来BOOST_HAS_TR1_TUPLE需要定义来告诉std::tr1::tuple已经定义的boost .

当我尝试编译包含这些标题的文件时,我遇到了类似的错误,然后在我定义时它们就消失了BOOST_HAS_TR1_TUPLE.
