Problems with KDevelop when using Qt QGLWidget

[Peyre]

Hi,

I need to implement an application for my job and I have found quite pretty to
use KDevelop in that goal. Further more, I need to use OpenGL libraries for
rendering. Whereas everithing was alright up to now, the compiler fails since 
I use QGLWidget.

In fact, all I have done is to create a new class whose header is:

#ifndef MAINVIEW_H
#define MAINVIEW_H

#include <qwidget.h>
#include <qgl.h>

class MainView : public QGLWidget{
	Q_OBJECT
public: 
	MainView();
	~MainView();
};

#endif

I have not added anything yet in the mainview.cpp file.
When compiling the folowing messages are returned.

gmake: Entering directory `/home/peyre/these/dev/learning/sample3/sample3'
g++ -DHAVE_CONFIG_H -I. -I. -I.. -I/usr/local/qt/include  -I/usr/X11R6/include    -O0 -g3 -Wall    -c mainview.cpp

collect2: ld returned 1 exit status
gmake: *** [sample3] Error 1
gmake: Leaving directory `/home/peyre/these/dev/learning/sample3/sample3'
*** échoué ***

Maybe Qt is not installed correctly. If this is the case, could somebody help me
to install it in the good way.

I don't know what to do anymore and I'm feeling desperate, so PLEASE HELP !
