交叉编译Qt5.12.8到树莓派3B+

硬件

主机系统：Ubuntu16.04

树莓派3B+系统：Raspbian

 

1 准备Raspberry Pi

/etc/apt/sources.list中的编辑源列表，并取消注释deb-src行

sudo nano /etc/apt/sources.list

更新，下载需要的开发包

sudo apt-get build-dep qt4-x11
sudo apt-get build-dep libqt5gui5
sudo apt-get install libudev-dev libinput-dev libts-dev libxcb-xinerama0-dev libxcb-xinerama0

2准备Linux主机

创建文件夹

mkdir ~/raspi
cd ~/raspi

克隆交叉编译工具链

git clone https://github.com/raspberrypi/tools

将工具链二进制目录添加到PATH。打开.bashrc并在文件末尾添加行

nano ~/.bashrc
export PATH=$PATH:～/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin
