[TJSonic]

When im trying to compile any GL application im getting an error:

What can it be?

Hi,

I am getting the same errors. Basically, can anyone please show how to use Qt OpenGL API on Symbian. I am trying to run the "Hello GL" example on Symbian. I am able to run it fine on Windows platform but not in Symbian.

Thanks in advance.

Regards,

Hi,

I came to know that Symbian uses "OpenGL ES" instead of "OpenGL". Then, I tried to run, "Hello OpenGL ES". Still, I got errors. But, i resolved them by including "#include <GLES/egl.h>".
Now, I am getting error, "Specified file '\S60\devices\S60_3rd_FP2_SDK_v1.1\epoc32\release\ WINSCW\udeb\QtOpenGL.lib' not found". I tried searching for this file but could not find it neither in Symbian SDK nor in Qt SDK folder.

Two things. Are you running on the simulator? If so, it doesn't support OpenGL, so it'll give you this error. Also you can't use deprecated OpenGL commands like GLBegin and many others. I'm struggling with this myself as all the frustrum, perpective and color and lighting information has to done in shaders now. The new versions of OpenGL will work the same way. For information on OpenGL ES and some code that helps either use the Qt3d engine on Gitorious for code or the Imagination technology SDK. You can download both for free, they have a lot of example code on how to use OpenGL ES. Unfortunately, I haven't found an example that uses a simple frustrum as the Hello OpenGL ES example uses ortho only.
