Problem cross compiling (QT5) Qt3D to raspberry Pi

Beoborg

Hi,
I have created working cross compile environment to my linux mint laptop. I was able to deploy
simple helloworld app to my rpi. Now I have tried to get teapot example to work, but no luck.
Teapot qt example is here:
"http://doc-snapshot.qt-project.org/qt3d-1.0/qt3d-teapot.html"

There is something wrong with my teapotview constructor, but I don't now what it is..
Does anyone know what is the problem, I have run out of ideas here?

Error print:
@In file included from ../qt5-raspberrypi-example/main.cpp:2:0:
../qt5-raspberrypi-example/teapotview.h: In constructor 'TeapotView::TeapotView(QWidget*)':

QGLview is now a subclass of Qwindow not Qwidget.

Just change the constructor argument to:
@TeapotView(QWindow *parent = 0)@

And you should be good to go.

The documentation for QT3D is atrocious now'a'days.

But you can checkout updated examples directly from the git repos.
