[KDE/Mac] [Kexi] Predicate qt5/macos porting

[Wojciech Kosowicz]

Hello, 

I have started porting Kexi application on MacOs X. It is ongoing with Qt5 porting. I started porting with Predicate repository that is future equivalent of KexiDB. I managed to port successfully on qt5 and it builds under Linux. However under MacOs  X I received messages like:

In file included from /Users/wojtek/macos/src/predicate/Predicate/expression/ExpressionData.h:26:
/Users/wojtek/macos/src/predicate/Predicate/Utils.h:530:24: error: calling a private constructor of class 'QString'

2 errors generated.

That turns out to be true as qstring does have this constructor as private if some conditions are fullfiled:

private:
#if defined(QT_NO_CAST_FROM_ASCII) && !defined(Q_NO_DECLARED_NOT_DEFINED)
    QString &operator+=(const char *s);
    QString &operator+=(const QByteArray &s);
    QString(const char *ch);
    QString(const QByteArray &a);
    QString &operator=(const char  *ch);
    QString &operator=(const QByteArray &a);
#endif

I installed using normal installer. So my question if anyone has run into this problem? :)
