    • f66c1db16c050c9d685a44a38ad7c5cf9f6fcc96 (qt/qtbase/dev)

      Have link error:

      mydialog.obj:-1: error: LNK2001: unresolved external symbol "struct QMetaObject const MyLibrary::staticMetaObject" (?staticMetaObject@MyLibrary@@3UQMetaObject@@B)

      Error happen because of the following line in code (disappears when commented out):

      mydialog.cpp:

      QMetaEnum myEnum = QMetaEnum::fromType<MyLibrary::MyEnumClass>();

      mylibrary.h:

      namespace MyLibrary
{ 
Q_NAMESPACE 

enum class MYLIBRARYSHARED_EXPORT MyEnumClass
{
...
}; 

Q_ENUM_NS(MyEnumClass)

...
} // namespace MyLibrary

      Found no solution in Internet, seems Qt bug.
