[Solved] Error while compiling QtWebKit 2.2 with 3D canvas

[Luc4]

Hi! I'm trying to build QtWebKit 2.2 with 3D canvas and support for WebGL for Qt Embedded against Qt 4.7.2. This is what I get:

Any idea why I'm getting this error? I found nothing around.
Thanks!

Problem was not 3d canvas but the 2d accelerated canvas option, which is not supported. Problem solved.
