Port codec Librasries
In this section, we will copy codec related files from original VLP Yocto build.
i.e. core-image-qt-smarc-rzg2l.tar.bz2 or core-image-weston-smarc-rzg2l.tar.bz2
Pleaes copy this .bz2 file to Ubuntu SD card and run below instruction on reference board
unzip core-image-qt-smarc-rzg2l.tar.bz2 or core-image-weston-smarc-rzg2l.tar.bz2 to folder "yocto"

Port Qt
You can port Qt by following 3 methods
- Port from VLP
- Compile & Install Qt from source
- Install Qt by apt-get
Port from VLP
In this section, we will copy Qt5.6.3 related files from original VLP Yocto build.
i.e. core-image-qt-smarc-rzg2l.tar.bz2
Pleaes copy this .bz2 file to Ubuntu SD card and run below instruction on reference board
unzip core-image-qt-smarc-rzg2l.tar.bz2 to folder "yocto"
(For other version of Qt, you can modify Yocto meta-qt5\recipes-qt\qt5, please inqury Qt company for higher version QT integration)
| Port Qt lib |
| cd yocto cp -rd usr/share/qt5 /usr/share/ cp -rd usr/lib64/qt5 /usr/lib/aarch64-linux-gnu/ cp -rd usr/lib64/libQt* /usr/lib/aarch64-linux-gnu/ cp -rd usr/lib64/pkgconfig/Qt* /usr/lib/aarch64-linuxgnu/pkgconfig/ export QT_QPA_PLATFORM=wayland export QT_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins/ |
Start Weston RZ-G/RZ-G2 BSP Porting Ubuntu#Start Weston desktop
Then run the Qt example in /usr/share/qt5/examples
Compile from source
You can download qt5 source to reference board and compile on board.
Or cross compile qt5 on PC
Or compile qt5 in PC QEMU
Here we compile qt5 on board
| compile qt5 |
| download qt5 source code by git (ignore) mkdir qt5-build cd qt5-build make make install （rsync to SD） |
We suggest to compile the qt5 with scrips
Notes: About the flags parameter in configure of Qt5. -qpa should be set as wayland or wayland-egl. We didn't support xcomposite-egl option
Install Qt by apt-get
apt-get install qt5-default qtwayland5
Notes: The above installation commands can only run part of Qt functions. If you need more functions, you need to continue installing Qt related packages.
Qt APPs development and testing
This section introduce how to develop Qt application on PC.
SDK build and installation
bitbake core-image-qt -c populate_sdk
The generated installation file is located at:
build/tmp/deploy/sdk/poky-glibc-x86_64-core-image-qtaarch64-smarc-rzg2l-toolchain-3.1.14.sh
Install this SDK to PC, default folder is /opt/poky/3.1.14
setup SDK runtime environment
source /opt/poky/3.1.14/environment-setup-aarch64-poky-linux
