前言

Qt6.22LTS版本正式推出了,刚好有个项目,使用的linux屏资源比较好,准备使用Qt6.22,记录下在ubuntu20.04.3下安装Qt6.22的步骤

一、安装步骤1.安装ubuntu20.04.3

直接到ubuntu网站,下载该安装镜像,在虚拟机下安装即可

2.更新ubuntu镜像下载源2.1 修改 sources.list文件

不要使用ubuntu桌面的设置来设置为国内下载源,直接修改/etc/apt/sources.list文件

使用 sudo gedit /etc/apt/sources.list打开该文件

删除文件内所有内容后,使用阿里云镜像

# 阿里云镜像 deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse # deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse # deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse # deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse # deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse # deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse2.2 更新操作

在终端内运行

sudo apt update sudo apt upgrade

若执行 sudo apt upgrade 提示以下错误,是因为某个进程锁住了文件,我是直接重启后再upgrade,或参考其他方法,杀死进程,删除导致锁定的文件

Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend xxxx3.替换系统的vim

ubuntu自带的vim是tiny版,经常会有奇怪的字符,替换系统自带的vim

sudo apt remove vim-common sudo apt install vim4. 安装ifconfig支持

ubuntu默认没有安装ifconfig,需要手动安装

sudo apt install net-tools5.安装sshd

ubuntu默认没有安装sshd,需要手动安装

sudo apt install openssh-server6.安装gcc编译器

sudo apt-get install build-essential sudo apt-get install libgl1-mesa-dev

安装完毕后,控制台输入gcc -v查看版本号,我的是9.4

注:安装libgl1-mesa-dev,避免Qt在编译工程时出现

/usr/bin/ld: cannot find -lGL错误7.安装Qt
