See Qt5.1x.x_Release.md in tool-chain package for details
Note that the names of all paths in the document cannot be changed, otherwise it will cause compilation or running errors.
- Compile
On the host side, enter the Qt project directory, qmake && make.
- Run
Demos are provided in the tool chain. After the deployment is completed, the user can build the demo on the host side and run the demo on the tartget side to test whether the deployment is successful.
After deciding which backend to use, you can modify the /etc/profile.d/target_qtEnv.sh in target, uncomment the environment variables of corresponding backend to keep it in effect.
# For example, using XCB, then uncomment the XCB part
#XCB
export QT_QPA_PLATFORM=XCB
export QT_QPA_EGLFS_INTEGRATION=XCB_EGL
