std type_traits conflict with Qt type_traits

I have Qt 5.8 installed and i get this error. I also have CONFIG += c++14 in my pro file and i also tried with c++11.

/usr/include/x86_64-linux-gnu/qt5/QtCore/qtimer.h:106: error: ‘is_same’ is not a member of ‘QtPrivate’!QtPrivate::is_same<const 

also

/usr/include/c++/5/type_traits:958: note:   ‘std::is_same’
     struct is_same;
