Here's example 1, and under Qt6 the Qt::endl line causes compiler error: "MyLib::Qt has not been declared". This code is in my compat.h file which does not set a namespace. Why is it even referencing MyLib:: ?? Notice the SkipEmbyParts macro works fine.

// Example 1
#if QT_VERSION < QT_VERSION_CHECK(5, 14, 0)
#define QT_COMPAT_SKIPEMPTYPARTS                   QString::SkipEmptyParts
#define QT_COMPAT_ENDL                             "\n"
#else
#define QT_COMPAT_SKIPEMPTYPARTS                   Qt::SkipEmptyParts
#define QT_COMPAT_ENDL                             Qt::endl
#endif

And here's example number 2, in this case the ::Qt::flush causes compiler error: "Unexpected qualified id before '::' token". I tried to prefix my manipulator with :: so that no higher level namespace would be assumed...but that chokes too.

// Example 2
#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
#define QT_COMPAT_FLUSH                            flush
#else
#define QT_COMPAT_FLUSH                            ::Qt::flush
#endif

Can someone help me fix my macros?
