初学银河麒麟linux笔记 第三章 QT缺少的模块下载、更新软件源操作

在共享文件夹里将WINDOWS里已经编写好的QT程序编译之后，提示

Qt5: Unknown module(s) in QT: serialport

经查询，需要安装对应的模块库，写入

sudo apt-get install libqt5serialport5-dev libudev-dev

 但命令端提示

“无法定位软件包”

经查询，是软件源需要进行更新，国内比较常用的是清华的软件源

首先

sudo cp /etc/apt/sources.list /etc/apt/sources.list.old //先把源文件复制到sources.list.old

然后对etc/apt/里的sources.list进行修改，我这里由于一直设置的只读，因此采用的vim修改，即

cd /etc/apt/
sudo vim sources.list

弹出编辑页面，将软件源复制进去

我这里采用的是

deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://archive.kylinos.cn/kylin/KYLIN-ALL 4.0.2sp2-desktop main restricted universe multiverse

注意：银河麒麟系统里每个“https”都要改为“http”，否则识别不出。当地址变红说明格式正确

改完后，按esc按钮，再按":"可输入执行指令，按回车键结束

一般是采用“w”保存，“q”退出。由于我的文件是只读且权限是root，因此采用了

:w !sudo tee %

进行保存。

退出修改界面后，可在窗口上查看文件是否发生变化

确定修改完毕后，保持联网状态，输入

sudo apt-get update

可能会出现这个问题

E: 无法获得锁 /var/lib/apt/lists/lock - open (11: 资源暂时不可用)
E: 无法对目录 /var/lib/apt/lists/ 加锁

这时进行解锁

sudo rm /var/lib/apt/lists/lock

然后再进行更新

sudo apt-get update

一般就没问题了

等待软件源更新完毕之后，再安装对应的模块库

sudo apt-get install libqt5serialport5-dev libudev-dev

安装完毕后编译qt，模块已成功下载，该问题已解决。

下面是ＱＴ依赖的所有的库，构建运行过程中缺少哪一个库，找到后执行sudo apt-get install＋库
