Could not open egl display Error on imx6q

newbie9899

Hello,

I cross-compile Qt5 with buildroot-2016.11
My board is an imx6q from Toradex.

I have this problem when I want to execute my program:
QML debugging is enabled. Only use this in a safe environment.
QEglFSVivIntegration will set environment variable FB_MULTI_BUFFER=2 to enable double buffering and vsync.
If this is not desired, you can override this via: export QT_EGLFS_IMX6_NO_FB_MULTI_BUFFER=1
Could not open egl display
Aborted

My default graphical platform is eglfs
On buildroot I selected :

open GL support
- open GL API (OpenGL ES 2.0+)
- openGL module
freescale im.x librairies: imx-gpu-viv

Before I use buildroot-2014.08 and it works!
I need some help to resolve this problem!

Hi and welcome to devnet,

Did you try to contact the folks from Toradex directly ? They might have more experience with that kind of scenario.

I had a similar problem, I can try to help if I need to:

Using ldd, run on your application and post the output here.
ldd /path_your_app/app
Execute the command below and post the output here:
zcat /proc/config.gz
