5 QT application development Qt is the faster, smarter way to create innovative devices, modern UIs & applications for multiple screens. Cross-platform software development at its best. The MYD- Y6ULX uses Qt 5.6.2 version. In Qt application development, it is recommended to use QtCreator IDE.It can be developed Qt application more easier, automated cross- compiler for the development board of the ARM architecture. -
Page 31: Install Qtcreator
In order to QtCreator use Yocto SDK, we need add environment to QtCreator, modify the file "/opt/qtcreator-4.1.0/bin/qtcreator.sh". Add below command before the line "#! /bin/sh": $ vi /opt/qtcreator-4.1.0/bin/qtcreator.sh source /opt/myir-imx6ulx-fb/4.1.15-2.0.1/environment-setup-cortexa7hf-neon-poky-linux-gnueabi #! /bin/sh # Use this script if you add paths to LD_LIBRARY_PATH # that contain libraries that conflict with the # libraries that Qt Creator depends on. -
