      Following build issue during the build with visual studio:

       

      qvariant.h(54): error C2888: 'const bool qIsRelocatable<QT_AME_NAMESPACE::QVariant>': symbol cannot be defined within namespace 'QT_AME_NAMESPACE'

       

      The problem isn't the code of qvariant.h, it's visual studio compiler issue as explain here.

      The workaround is to change:

      template<> constexpr inline bool QtPrivate::qIsRelocatable<QVariant> = true;

      by:

      namespace QtPrivate 
{
    template<> constexpr inline bool qIsRelocatable<QVariant> = true;
}

      Patch attached.
