porting qt to rockchip platforms
On ubuntu of x86 platform
The following operations are performed on ubuntu on the x86 platform
Cross-compilation tools

* If you encounter an error similar to the following, /dir/to/source/sol.hpp:7194:59: error: ‘numeric_limits’ is not a member of ‘std’ add the following line to the file #include <limits>
sudo chmod +x auto.sh sudo ./auto.sh
- after success you can see

qt creator installation
download installation tools
wget https://download.qt.io/archive/qt/5.12/5.12.2/qt-opensource-linux-x64-5.12.2.run or you can download them from [here]
installation
sudo chmod +x qt-opensource-linux-x64-5.12.2.run sudo ./qt-opensource-linux-x64-5.12.2.run
env
indeed tools
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev -y
add kits
add gcc and g++
Then you can add gdb as you would gcc above
add a new device
let's coding
creat a new project
main code
then choose Debugger->rock->Debug, just click it
copy the project to you board which has a desktop
scp build-demo4-ext4-Debug radxa@192.168.2.211:~
on board
The following operations are performed on ubuntu on the rk3566 or rk3568 rk3588 platform
- env
sudo apt-get install libqt5gui5 -y
- Execute the program
sudo chmod +x ./demo4
./demo4
or click it
