Strange error with Qt-4.3.0rc1
Message 1 in thread
Hi List,
Got it working with Qt-4.2.3 but after compiling this against Qt-4.3.0rc1 I
get this :
CEventData.h: In member function âvoid
CEventData::qt_check_for_QOBJECT_macro(const T&) const [with T =
CEventObjectSelectedData]â:
/usr/local/Trolltech/Qt-4.3.0rc1/include/QtCore/qobject.h:409: instantiated
from âT qobject_cast(QObject*) [with T = CEventObjectSelectedData*]â
CEventObjectSelectedData.cpp:84: instantiated from here
CEventData.h:20: error: void value not ignored as it ought to be
Hmmmm. And on line 20 of CEventData, there is only the QOBJECT macro.... ???
//***************************************************************************
#ifndef CEVENTDATA_H
#define CEVENTDATA_H
#include <QtCore>
#include "EventLibExport.h"
class EVENTLIBINTERFACE CEventData : public QObject
{
Q_OBJECT <<<< Line 20
public:
CEventData();
virtual ~CEventData();
CEventData(const CEventData& eventData);
CEventData& operator= (const CEventData& eventData);
virtual CEventData* clone() const = 0;
virtual CEventData* create() const = 0;
virtual void copy(CEventData* destination) const = 0;
};

Did you make sure that moc is recreating all your generated files?
When you switch qt versions, make sure you make clean or make rebuild.
Cheers,
Peter

Hi Peter,
Yes, I did. Because of prior experiences and the speed of current hardware, a
complete rebuild is done every time.
But thank you. It was a good thought though.
I think this is more an issue for the Buglist. I think I'll post one. A shame
though, as some ORACLE issues were solved in this rc1 version.
Kind Regards,

What's in EventLibExport.h?
Try removing that header file - just for the purpose of isolating the problem.
Which compiler is this by the way?
