This guide is tested with only xcb platform for widget applications
On Linux, the xcb QPA (Qt Platform Abstraction) platform plugin is used. It provides the basic functionality needed by Qt GUI and Qt Widgets to run against X11. https://doc.qt.io/qt-5/linux-requirements.html
you can watch also Youtube video (this one is for different configuration but it can give an idea):
Qt Configuration on jetson nano Plese watch the video carefully. :)
Update and upgrade the ubuntu(jetpack 4.6)
sudo apt update
sudo apt upgradeInstall qt5-default for xcb option
sudo apt-get build-dep qt5-defaultIf you see an error like this:
E: You must put some 'source' URIs in your sources.listThen you will need to enable the "Source code" option in Software and Updates > Ubuntu Software under the "Downloadable from the Internet" section. This setting can also be found by running software-properties-gtk.
Otherwise If this package is not installed correctly after configuration you will see like this:
ERROR: Feature 'xcb' was enabled, but the pre-condition 'features.thread && libs.xcb && tests.xcb_syslibs && features.xkbcommon-x11' failed.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/opt/qt5jnano/sysroot/usr/local/qt5jnano'.
Prior to reconfiguration, make sure you remove any leftovers from
the previous build.Do not worry about the notes. This is for only base module.
After configuration compile the base.
