Error with QT5.7.0 quick renderer 2d on a linuxfb device

[A Former User]

Hello everyone! After some hard time I finished building Qt5 on a embedded device that uses linuxfb only and no hardware acceleration. When I execute an example with my environment variable QT_QPA_PLATFORM = eglfs I get the following error:

Could not open egl display
Aborted

I did the procedure described in the Quick Renderer 2d page with the environment variable QMLSCENE_DEVICE=softwarecontext and the dummy openGL lib.
I have no problem using the linuxfb but I need eglfs in order to run qtwebengine.

Any idea about the problem?

Using QT_QPA_PLATFORM=linuxfb give me the following errors:

QOpenGLWidget is not supported on this platform.
This plugin does not support createPlatformOpenGLContext!
This plugin does not support createPlatformOpenGLContext!

Problem was really QT_QPA_PLATFORM=eglfs. After changed to linuxfb and solved QML dependencies it worked! :)
