Undefined reference to '_imp__ZN9QGLWidgetC2ERQ9QGLFormat...'

[NorskQt]

Hi there,

I just quit MS .NET and started with QT. I was implementing an example from QT's tutorial "hellogl" starting from the scratch. I got the error message shown above + 14 more of them, related to formats and widgets. I searched every possible place to find answer why I have got this error message but I could not find any answer. So here I am! What is causing this error? Any idea?

I am very surprized that such a small code will create so many error messages.

Thanks for all the suggestions and help.
OS : Windows7

have you added opengl module t your pro file ?

[NorskQt]

I put this one in the header file :
#include <QTOpenGL/QGLWidget>

and the rest of the "Widget" code starts like this and foolows the example with a different name and namespace :

class QtLogo;

namespace VisualPresenters
{

class Canvas3D : public QGLWidget
{

    Q_OBJECT

public:
    Canvas3D(QWidget* parent = NULL);

    ~Canvas3D()

Thanks for the response. Should I need to add more or am I missing something here?

Regards.

You are right! I have added

QT += opengl

to .pro file and it seems that this part of the problem is solved.

Thank you!

OK! Next time I will put @tag to my code snippets.

Sorry! :o)

First: Qt is not QT(QuickTime)
Second: What do version of Qt you use? May be it was build without opengl support?
