[Aleksey_K 0]

Project builds just fine in Linux, however fails to link under Windows.

1st issue (solved)

2nd issue:

In the library .pro file VERSION variable is defined and resulting library has name MyLibrary1.lib. Thereafter I get error:

:-1: error: LNK1181: cannot open input file 'MyLibrary.lib'

What is better way to solve the problem here: remove VERSION or fix .pro file? How?

3rd issue:

Another 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

And how to solve the 3rd one?
