linux arm上怎么编译qt5.14.2

以下是在Linux ARM上编译Qt5.14.2的步骤：

1. 安装必要的软件包：

sudo apt-get update
sudo apt-get install build-essential libgl1-mesa-dev libfontconfig1-dev libdbus-1-dev libfreetype6-dev libicu-dev libinput-dev libxkbcommon-dev libsqlite3-dev libssl-dev libpng-dev libjpeg-dev libglib2.0-dev zlib1g-dev libraspberrypi-dev

2. 下载Qt5.14.2源代码

wget http://download.qt.io/official_releases/qt/5.14/5.14.2/single/qt-everywhere-src-5.14.2.tar.xz
tar -xf qt-everywhere-src-5.14.2.tar.xz
cd qt-everywhere-src-5.14.2

3. 配置Qt

./configure -release -opengl es2 -device linux-rasp-pi3-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -no-use-gold-linker -v

4. 编译Qt

make -j4

5. 安装Qt

make install

6.将Qt添加到环境变量中

echo 'export PATH=~/raspi/qt5pi/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

7.测试Qt

cd ~/raspi/qt5pi/examples/widgets/analogclock
~/raspi/qt5pi/bin/qmake
make
./analogclock -platform eglfs

完成以上步骤后，您将在Linux ARM上成功编译Qt5.14.2。
