交叉编译QT5的库，参考资料

构建sysroot
在主控板上安装rsync,首先确保主控板已经脸上基础的网络
# pull一下源
sudo apt update
# 安装rsync
sudo apt-get install rsync
# 安装ssh客户端
sudo apt-get install openssh-client
# 安装ssh服务端
sudo apt-get install openssh-server

sudo apt-get update
sudo apt-get install rsync
sudo apt-get install openssh-client
sudo apt-get install openssh-server
sudo apt-get install libclang-dev
sudo dnf install clang-devel
sudo apt install libssl-dev gperf pkg-config git bison ninja-build make build-essential libclang-dev libfontconfig1-dev libfreetype6-dev libx11-dev libx11-xcb-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libxcb-glx0-dev libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev libxcb-util-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev libatspi2.0-dev libgl1-mesa-dev libglu1-mesa-dev freeglut3-dev建议提前固定好设备的IP，我这里使用路由器固定设备IP为192.168.50.112
将当前开发板上的文件系统同步到虚拟机rootfs_copy文件夹
- 在虚拟机上创建rootfs_copy文件夹
mkdir -p ~/WorkSpace/rootfs_copy - 在虚拟机上创建~/.ssh/config 文件:
vim ~/.ssh/config - 在主控板上允许虚拟机登录
# 通过其他用户登录（如 linaro）
ssh linaro@192.168.50.112
# 切换到 root（需要知道 root 密码）
su - root
# 编辑 SSH 配置文件
nano /etc/ssh/sshd_config
# 输入以下内容
PermitRootLogin yes # 允许 root 登录
PasswordAuthentication yes # 允许密码认证
# 保存后重启ssh服务
systemctl restart ssh- 开始同步
sudo rsync -avx root@192.168.137.202:/ ~/WorkSpace/rootfs_copy
nfs挂载和rsync同步文件，有些软连接库是使用绝对路径，交叉编译Qt源码时会出错。我们可以使用symlinks修改绝对路径为相对路径，在虚拟机上使用安装命令：
sudo apt-get install symlinks使用命 令：sudo symlinks -rc ~/WorkSpace/rootfs_copy。
