qt5.14.1:qt5.14.1.run
opencv4.5.5:opecv4.5.5压缩包
1.国内换中科大源，加快下载速度
cd /etc/apt/
sudo gedit sources.list
替换成如下内容
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
保存
打开命令行
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential
2.ARM扩大SWAP分区
1）
cd /opt
sudo mkdir image
cd image
sudo touch swap
sudo dd if=/dev/zero of=/opt/image/swap bs=1024 count=2048000
sudo mkswap /opt/image/swap
sudo swapon /opt/image/swap
#确认新增加的2G交换空间已经生效，使用命令free
free -m
2）
sudo gedit /etc/fstab
#在文件最后加入：
/opt/image/swap /swap swap defaults 0 0
