I'm sorry, but this really looks ugly, and doesn't seem needed at all.
We already have a working solution for this problem (which we already
had for the RPi, and we solved in a much nicer way I believe) :
(1) The OpenGL implementation should install proper pkg-config files
to allow Qt5 to get the right compilation flags/libraries. See the
"gpu-viv-bin-mx6q: add pkgconfig files for EGL and OpenGLESv2"
patch that Fatih has sent today.
(2) We already have a mechanism in qt5.mk to customize the EGL
platform hook implementation. It just need to be extended to cover
the i.MX6 case. I.e, next to:
ifeq ($(BR2_PACKAGE_RPI_USERLAND),y)
QT5BASE_EGLFS_PLATFORM_HOOKS_SOURCES = \
$(@D)/mkspecs/devices/linux-rasp-pi-g++/qeglfshooks_pi.cpp
endif
one should add:
ifeq ($(BR2_PACKAGE_GPU_VIV_BIN_MX6Q),y)
QT5BASE_EGLFS_PLATFORM_HOOKS_SOURCES = \
$(@D)/mkspecs/devices/linux-imx6-g++/qeglfshooks_imx6.cpp
endif
If someone makes a patch with both of these changes, then it'll have my
Acked-by.
Best regards,
Thomas
