Cross-compiling Qt 5.6 for HW accelerated OpenGL with eglfs fails: Failed to load EGL device integration "eglfs_brcm"
-
Hi all,
I'm following the guide for cross-compiling Qt 5.6 for HW accelerated OpenGL with eglfs on Raspbian Jessie, see:
https://wiki.qt.io/RaspberryPi2EGLFS#Step_by_step
I'm using a Raspberry Pi 2, host machine is running Ubuntu 16.04.
./qopenglwidget qt.qpa.egldeviceintegration: Failed to load EGL device integration "eglfs_brcm" Could not find DRM device! AbortedMore info:

AbortedSpecifying the platform:
./qopenglwidget -platform eglfsYields the same output. Running it and specifying linuxfb creates the user interface but fails after a while (probably to be expected, just to show that the app seems to be working but not using eglfs).

QOpenGLWidget: Failed to create contextI've searched for this problem but it seems too specific to yield enough results that help solve it or pinpoint to possible causes.
Can anyone provide some pointers as to how I can begin to solve this problem or tell me what the exact prerequisites are for making this work? I'm assuming that, since the guide was written, new Jessie updates were issued which could cause my problem.

@AimedSquid you could solve thel issue?, because I have the same error.

hi
could not find drm device
is becasue the device driver need its dtb
device tree overlay
there are two overlays and you need to add one to config.txt@eliar can you be more clear how to do that...
