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:
 
 
===S5P4418平台的编译===
 
<syntaxhighlight lang="bash">
 
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
 
</syntaxhighlight>
 
===S5P6818平台的编译===
 
<syntaxhighlight lang="bash">
 
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
 
</syntaxhighlight>
 
===Allwinner H3平台的编译===
 
<syntaxhighlight lang="bash">
 
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
 
</syntaxhighlight>
 
===Allwinner H5平台的编译===
 
<syntaxhighlight lang="bash">
 
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
 
</syntaxhighlight>
 
===Amlogic S905平台的编译===
 
<syntaxhighlight lang="bash">
 
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
 
</syntaxhighlight>
 
 
===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:
 
<syntaxhighlight lang="bash">
 
. /usr/bin/setqt5env
 
</syntaxhighlight>
 
 
Qt4,使用 setqt4env:
 
<syntaxhighlight lang="bash">
 
. /usr/bin/setqt5env
 
</syntaxhighlight>
 
 
例如运行上一章节编译的QtE-Demo:
 
<syntaxhighlight lang="bash">
 
./QtE-Demo -qws
 
</syntaxhighlight>
 
 
===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:
 
<syntaxhighlight lang="bash">
 
. /usr/bin/setqt5env
 
/root/QtE-Demo -qws&
 
</syntaxhighlight>
 
如果是 Qt4,请将setqt5env改为setqt4env。
