The main purpose is to build QT 5.4 libraries with OpenGL ES2 support for ARM embedded system (conga-QMX6 based on Freescale i.MX6 ARM Cortex A9).
1) First of all , you need to install LTIB. You can use this instructions for install LTIB under Ubuntu 14.04
2) Download source code of QT 5.4 from official site (by this link http://download.qt.io/official_releases/qt/5.4/5.4.1/single/qt-everywhere-opensource-src-5.4.1.zip)
3) Unpack downloaded file at any directory (for example into home dir).
4) Edit platform config file qmake.conf (located in qtbase/mkspecs/devices/linux-imx6-g++/ ):

include(../common/linux_device_pre.conf) EGLFS_PLATFORM_HOOKS_SOURCES = $$PWD/qeglfshooks_imx6.cpp ROOTFS=/home/tarkus/SARMAT/ltib/rootfs QMAKE_INCDIR += $$ROOTFS/usr/include QMAKE_LIBDIR += $$ROOTFS/usr/lib QMAKE_LFLAGS += -Wl,-rpath-link,$$ROOTFS/usr/lib QMAKE_LIBS_EGL += -lEGL 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 include(../common/linux_arm_device_post.conf) load(qt_config) |
5) Create bash script file into qtbase directory:

#!/bin/sh ./configure -v -opensource -confirm-license -make libs -device imx6 -prefix /opt/QtEmbedded-5.4.1-arm -device-option CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-fsl-linux-gnueabi- -no-pch -no-openvg -no-opengl -no-icu -no-c++11 -eglfs -no-xcb -directfb -opengl es2 -no-openssl -no-xvideo -no-cups -no-glib -qt-zlib -no-nis -no-cups -no-openssl -qt-libpng -qt-libjpeg -no-audio-backend -no-separate-debug-info -no-rpath -compile-examples |
Don’t forget to change paths in case of any difference. If you use this instruction no changes are needed.
6) Run configuration script, created in previous step.
7) Run commands ‘make & make install’ (under root user)
As the result QT 5.4 for ARM will be built and deployed into /opt/QtEmbedded-5.4.1-arm directory.
