[meta-freescale] Error 0x300b in Qt5 applications with EGLFS

But do you remember what specific versions and configurations you were using? Also how exactly are you defining no x11 in distro flags? Do you mean not adding it or is there a way to specifically block it?
Here’s the exact procedure I can follow today showing that it does not work. It’s possible I am doing something incorrect here but if that’s the case I would appreciate if someone could point it out. Starting from a fresh checkout of dora and the dora branch of meta-qt5.
repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b dora
git clone -b dora https://github.com/meta-qt5/meta-qt5.git
MACHINE=nitrogen6x . setup-environment build
I then add meta-qt5 to the bblayers.conf as well as adding the following to local.conf
CORE_IMAGE_EXTRA_INSTALL += " qtbase qtbase-tools qtbase-plugins qtbase-fonts cinematicexperience”
And then continue with.
Now qtbase fails because of eglvivante.h including X.h which in turns #define None 0L which breaks qurl.h. To work around this I add #define EGL_API_FB at the top of eglvivante.h as a hack and everything now compiles and the image is loaded onto the Nitrogen6X board.
Attempting to run the example results in the following.
root at nitrogen6x:/usr/share/cinematicexperience-1.0# ./Qt5_CinematicExperience
QXcbConnection: Could not connect to display
root at nitrogen6x:/usr/share/cinematicexperience-1.0# ./Qt5_CinematicExperience -p

X11 is said to be untested and causes compilation issues (eglvivante.h includes X.h whose #define None 0L breaks qurl.h). Framebuffer doesn’t appear supported as this thread demonstrates, same issue on Nitrogen6X as well so not isolated to Wandboard.
