It feels like I'm finally getting close to developing code on an i.MX6ULL EVK but my app won't run.

EGL_EXT_device_base missing


I'm using the fsl-image-qt5.

Build Configuration:

BB_VERSION = "1.30.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "Ubuntu-16.04"
TARGET_SYS = "arm-poky-linux-gnueabi"
MACHINE = "imx6ull14x14evk"
DISTRO = "fsl-imx-fb"
DISTRO_VERSION = "4.1.15-2.0.1"
TUNE_FEATURES = "arm armv7ve vfp neon callconvention-hard cortexa7"
TARGET_FPU = "hard"


There's report and resolution of the same error here: [OE] QT + eglfs backend - DragonBoard410c - 96Boards Forum

They're using Qt5.7 / Qt5.8 with eglf kms integration and it requires gbm ... I don't know what any of those things are yet.
