Hi all.
I am creating a DLL on Windows XP (i'm use 2005 Professional Edition) VC 2005 error:
After compilation , I get an error code from "Moc'ing imgdll.h ..."
Help understand what is going?

I have following files:
===================ImgDll_global.h================ ====
#ifndef IMGDLL_GLOBAL_H
#define IMGDLL_GLOBAL_H

#include <QtCore/qglobal.h>

#if defined(IMGDLL_LIBRARY)
# define IMGDLLSHARED_EXPORT Q_DECL_EXPORT
#else
# define IMGDLLSHARED_EXPORT Q_DECL_IMPORT
#endif

#endif // IMGDLL_GLOBAL_H
=========================imgdll.h================= =====
#ifndef IMGDLL_H
#define IMGDLL_H

#include <QGraphicsView>
#include "ImgDll_global.h"

class IMGDLLSHARED_EXPORT ImgDll : public QGraphicsView {
Q_OBJECT
public:
ImgDll(QGraphicsScene* pScene, QWidget* pwgt = 0);
~ImgDll();

public slots:
void f1(qreal value = 1.1);
void f2(qreal value = 1.1);
private:
qreal getCurr() const;
};
==========================imgdll.cpp============== =========
#include <QtCore/qmath.h>
#include "imgdll.h"

ImgDll::ImgDll(QGraphicsScene* pScene, QWidget* pwgt)
: QGraphicsView(pScene, pwgt){}
ImgDll::~ImgDll(){}
void ImgDll::f1(qreal value ){.....}
void ImgDll::f2(qreal value) {...}

After compilation Debug\BuildLog.htm contain following data:

What about adding IMGDLL_LIBRARY to the project defines?

Yes, you have defined "IMGDLL_LIB", not "IMGDLL_LIBRARY" as your code requires. Look carefully at the content of the first command line in your output listing.

Edit: Just noticed the OP was over two weeks ago. I hope you've figured this out by now. :)
