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
下面以下载并编译一个 QtE-Demo 为例，分别说明在各个平台编译一个 Qt应用程序的步骤：
3.1 S5P4418平台的编译
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平台的编译
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平台的编译
export PATH=/opt/FriendlyARM/toolschain/4.9.3/bin/:$PATH git clone https://github.com/friendlyarm/QtE-Demo mkdir build && cd build /usr/local/Trolltech/QtEmbedded-4.8.6-arm/bin/qmake ../QtE-Demo/QtE-Demo-Qt4.pro make
3.4 Allwinner H5平台的编译
export PATH=/opt/FriendlyARM/toolschain/a64-32bit-tootchain/bin/:$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平台的编译
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 在开发板上运行Qt程序
运行Qt程序之前，需要先设置环境变量，在开发板上执行以下命令即可：
Qt5，使用 setqt5env:
. /usr/bin/setqt5env
Qt4，使用 setqt4env:
. /usr/bin/setqt4env
例如运行上一章节编译的QtE-Demo:
./QtE-Demo -qws
5 开机自动运行Qt程序
以运行上一章节中的 QtE-Demo 程序为例，假设它放在 /root 目录，则你可以编辑 /etc/rc.local 文件，确否有以下内容：
. /usr/bin/setqt5env /root/QtE-Demo -qws&
如果是 Qt4，请将setqt5env改为setqt4env。
6 屏幕旋转
根据你所用开发板的CPU型号，点击下表中的链接，下载链接内的所有文件到本地:
| CPU名称 | Qt版本 | 屏幕旋转方法 |
| S5P4418 | Qt 5.9.1 | export ROTATION=-90 . setqt5env ./YourApp 可设置角度值为: 0, 90, 180, -90 |
| S5P6818 | Qt 5.9.1 | export ROTATION=-90 . setqt5env ./YourApp 可设置角度值为: 0, 90, 180, -90 |
| Allwinner H3 | Qt 4.8.6 | . setqt4env export QWS_DISPLAY='Transformed:Rot90' ./YourApp 可设置角度值为: 0, 90, 180, 270 |
| Allwinner H5 | Qt 4.8.6 | . setqt4env export QWS_DISPLAY='Transformed:Rot90' ./YourApp 可设置角度值为: 0, 90, 180, 270 |
| Amlogic S905 | Qt 5.9.1 | . setqt5env export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0:rotation=90 ./YourApp 可设置角度值为: 0, 90, 180, 270 |
