As you asked in another thread(http://developer.qt.nokia.com/forums/viewthread/6068/) before, do you try other exmaples? You can just make a QGLWidget yourself, and build to see what happen with your SDK or environment. By the way, which platform you are working with?

Yeah , this is not the same project , I have started a fresh project myself and added basic codes to IntializeGL,ResizeGL,paintGL and to draw a triangle…

but the errors haven’t changed…

By the way, which platform you are working with?

I’m working in Windows Xp with Nokia’s QT SDK for Nokia N97 mini

Do you build for desktop or symbian device ? Can you send your code to me, i can try it on my computer for you. Email: chuckgao.cg@gmail.com

Sure,… Thank you Chuck.Gao

The code have some wrong syntax. right one is modified
1. GamePlay::InitializeGL() —> GamePlay::initializeGL() in both header and source file
2. glViewPort —> glViewport
3. draw() —> GamePlay::draw()

I can build it on both Desktop(also simulator) and Symbian device, but it’ll crash some where.

k, I have change it as you said… but still the same errors are there…

did you get the output?

no, it’s OK for me. Maybe there have some problem with your environment or SDK, i’m not sure. You can paste the log on this thread, i think someone can resolve your problem

how to get the log? I couldn’t copy the error, it’s disabled…!
There is no log file in the debug directory..

Is it would work if I re-install the SDK

Have you added #include <gl.h> yourself? If so there is no need, QGLWidget takes care of all that for you. I seem to think there can be issues if OpenGL headers and Windows headers are #include’d in the wrong order.

No, I didn’t add them… now I’m re-installing the Qt SDK…

Good luck :-)

Um…. Let’s see… what if it’s still not working :(

I have re-installed the SDK… Now the errors are gone ,.. and application is running successfully.. except I’m not getting the exact output….

@Chuck.Gao : what was the output you got with the project?

The Project type is Qt Mobile Application , doesn’t it support OpenGL and should I go for OpenGL ES…

The mobile use OpenGL ES, but not OpenGL.
Output for what ? Sorry, i can’t see anything until the application crash.

You said that you got my app running on your sdk… right?
did you get any output in that?

I have drawn a triangle in that app…
