ldd /usr/local/qt5/bin/qdbusviewer
source /etc/profile.d/qt_xcb.sh
export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins
export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins/platforms
sudo ln -sf /usr/lib/aarch64-linux-gnu/qt5/plugins/platforms/libqxcb.so /usr/local/qt5/plugins/platforms
export QT_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins

@Sreeja Why does your app search for plug-ins in /home/cig/tools/plugins/platforms?

I have tried giving different export Path for QT_QPA_PLATFORM_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins
export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins/platforms. where i find libqxcb.so file.
