In our test our QtE-Demo application was under the /root directory. Make sure your "/etc/rc.local" file has the following contents:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">

</syntaxhighlight>

−
如果是 Qt4，请将setqt5env改为setqt4env。

If this is a Qt4 system you need to change "setqt5env" to "setqt4env".

1 Qt Versions

Qt has various versions for various platforms. Each Qt version has its own features and here a list of versions:

CPU Qt Version Display Driver OpenGL QtWebEngine Capacitive Touch ARM Board
S5P4418 Qt 5.9.1 EGLFS Yes Yes Multiple-point touch NanoPi S2/NanoPi M2A/NanoPi Fire2/NanoPC T2/Smart4418
S5P6818 Qt 5.9.1 EGLFS Yes Yes Multiple-point touch NanoPi M3/NanoPi Fire3/NanoPC T3
Allwinner H3 Qt 4.8.6 LinuxFB No No Single-point touch NanoPi-Duo/NanoPi-M1-Plus/NanoPi-M1/NanoPi-NEO-Air/NanoPi-NEO-Core/NanoPi-NEO
Allwinner H5 Qt 4.8.6 LinuxFB No No Single-point touch NanoPi-M1-Plus2/NanoPi-NEO-Core2/NanoPi-NEO-Plus2/NanoPi-NEO2
Amlogic S905 Qt 5.9.1 LinuxFB No No Single-point touch NanoPi-K2

2 Install Cross Compiler for Qt

(Note: we suggest users use a host PC running a 64-bit Ubuntu 16.04)
Here is a list of cross compilers for various CPUs and ARM boards:

CPU Qt Version Compiler & QtSDK
S5P4418 Qt 5.9.1 download link
S5P6818 Qt 5.9.1 download link
Allwinner H3 Qt 4.8.6 download link
Allwinner H5 Qt 4.8.6 download link
Amlogic S905 Qt 5.9.1 download link

Install a cross compiler by running the following commands: 

chmod 755 ./install.sh
sudo ./install.sh

3 Cross Compile Qt Program

We took QtE-Demo as an example to show how to compile a Qt program.

3.1 S5P4418 Platform

git clone https://github.com/friendlyarm/QtE-Demo
mkdir build && cd build
/usr/local/Trolltech/Qt-5.9.1-nexell32/bin/qmake ../QtE-Demo/QtE-Demo.pro
make

3.2 S5P6818 Platform

git clone https://github.com/friendlyarm/QtE-Demo
mkdir build && cd build
/usr/local/Trolltech/Qt-5.9.1-nexell64/bin/qmake ../QtE-Demo/QtE-Demo.pro
make

3.3 Allwinner H3 Platform

export PATH=/opt/FriendlyARM/toolschain/4.9.3/bin/:$PATH
git clone https://github.com/friendlyarm/QtE-Demo
mkdir build && cd build
/usr/local/Trolltech/QtEmbedded-4.8.6-arm/bin/qmake ../QtE-Demo/QtE-Demo-Qt4.pro
make

3.4 Allwinner H5 Platform

export PATH=/opt/FriendlyARM/toolschain/a64-32bit-tootchain/bin/:$PATH
git clone https://github.com/friendlyarm/QtE-Demo
mkdir build && cd build
/usr/local/Trolltech/QtEmbedded-4.8.6-arm-a64/bin/qmake ../QtE-Demo/QtE-Demo-Qt4.pro
make

3.5 Amlogic S905 Platform

export PATH=/opt/FriendlyARM/toolschain/a64-32bit-tootchain/bin/:$PATH
git clone https://github.com/friendlyarm/QtE-Demo
mkdir build && cd build
/usr/local/Trolltech/QtEmbedded-5.9.1-arch64/bin/qmake ../QtE-Demo/QtE-Demo.pro
make

4 Run Qt Application on ARM Board

Before you run a Qt application on a board you need to setup the board's environment variables by running the following commands on that board:

For Qt5 run setqt5env: 

. /usr/bin/setqt5env

For Qt4 run setqt4env: 

. /usr/bin/setqt4env

Run QtE-Demo: 

./QtE-Demo -qws

5 Auto-Run Qt Application on System Startup

In our test our QtE-Demo application was under the /root directory. Make sure your "/etc/rc.local" file has the following contents: 

. /usr/bin/setqt5env
/root/QtE-Demo -qws&

If this is a Qt4 system you need to change "setqt5env" to "setqt4env".

6 Display Rotation

Here is a list of methods you can use to rotate your display for various platforms:

CPU Qt Version Display Rotation
S5P4418 Qt 5.9.1 export ROTATION=-90
. setqt5env
./YourApp

Applicable rotation degrees: 0, 90, 180, -90
S5P6818 Qt 5.9.1 export ROTATION=-90
. setqt5env
./YourApp

Applicable rotation degrees: 0, 90, 180, -90
Allwinner H3 Qt 4.8.6 . setqt4env
export QWS_DISPLAY='Transformed:Rot90'
./YourApp

Applicable rotation degrees: 0, 90, 180, 270
Allwinner H5 Qt 4.8.6 . setqt4env
export QWS_DISPLAY='Transformed:Rot90'
./YourApp

Applicable rotation degrees: 0, 90, 180, 270
Amlogic S905 Qt 5.9.1 . setqt5env
export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0:rotation=90
./YourApp

Applicable rotation degrees: 0, 90, 180, 270
