[Interest] QtWebEngine on i.MX6 eglfs

[Filip Piechocki]

I am compiling Qt 5.9.1 inside a docker container running on the i.MX6
itself. My configure line:

./configure -opengl es2 -platform linux-imx6-g++ -prefix /usr -opensource
-confirm-license -release -c++std c++1z -make libs -nomake tests \
    -skip qtdatavis3d \
    -skip qt3d \
    -skip qtconnectivity \
    -skip qtgamepad \
    -skip qtcharts \
    -skip qtpurchasing \
    -skip qtscript

I;ve created a platform mkspec to get the i.MX6 specific device settings:

$ cat qmake.conf
#
# qmake configuration for linux-g++
#
QT_QPA_DEFAULT_PLATFORM = eglfs
MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

QMAKE_LIBS_EGL         += -lEGL -lGAL
QMAKE_LIBS_OPENGL_ES2  += -lGLESv2 -lEGL -lGAL
QMAKE_LIBS_OPENVG      += -lOpenVG -lEGL -lGAL

IMX6_CFLAGS             = -march=armv7-a -mfpu=neon -DLINUX=1 -DEGL_API_FB=1
QMAKE_CFLAGS           += $$IMX6_CFLAGS
QMAKE_CXXFLAGS         += $$IMX6_CFLAGS

COMPILER_FLAGS += -mfloat-abi=hard
LINKER_FLAGS   += -mfloat-abi=hard

EGLFS_DEVICE_INTEGRATION = eglfs_viv

load(qt_config)

There were some QtWebEngine deps lacking (libdbus-1-dev, gperf, bison,
flex) when compiling Qt, so then I did:

$ cd qtwebengine
$ qmake
$ make
