• Create a new automatic configuration script file

vi auto.sh

#!/bin/sh

mkdir -p  /opt/qtInstallDir

* 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

test@test-desktop:/opt$ ls /opt/qtInstallDir/
bin  doc  include  lib  mkspecs  plugins  translations

test@test-desktop:/opt$ ls /opt/qt5.9.4-arm/
 bin  lib  mkspecs

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 

add gdb 

add a new device

let's coding

creat a new project

main code

then choose Debugger->rock->Debug, just click it

on board

• env

sudo apt-get install libqt5gui5 -y 

• copy the project to you board which has a desktop

scp build-demo4-ext4-Debug radxa@192.168.2.211:~

• Execute the program

./demo4
or click it
