可以运行qtcoreator

编译时报错

1、cannot find -lGL

查看是否已安装
locate libGL
配置
sudo ln -s /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so
安装
sudo apt-get install mesa-common-dev
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev
如果安装不了，参考下一步中的替换apt源

2、缺少x11/xlib.h和xcb/xcb.h

sudo apt-get install libx11.dev

安装时可能报错依赖库版本错误解决办法：

sudo gedit /etc/apt/sources.list

该命令的作用是用gedit打开安装来源文件sources.list，替换安装源，使用阿里的云，将文件内容替换为以下内容

3、解决修改.pro文件保存时qt程序自动退出问题，主要受权限影响，修改权限即可。

4、18.04源

5、在Ubuntu上安装GCC

默认的Ubuntu存储库包含一个名为build-essential的元包，它包含GCC编译器以及编译软件所需的许多库和其他实用程序。

执行以下步骤安装GCC Compiler Ubuntu 18.04：

01、首先更新包列表：

sudo apt update

02、键入以下命令安装build-essential软件包：

sudo apt install build-essential

该命令将安装一堆新包，包括gcc，g ++和make。

03、要验证GCC编译器是否已成功安装，请使用gcc --version命令打印GCC版本：

gcc --version

Ubuntu 18.04存储库中可用的默认GCC版本是7.4.0

用到的指令
查看环境变量：env
临时指定链接库查找路径（多个路径可以用：隔开）：
export LD_LIBRARY_PATH=LD_LIBRARY_PATH:.:～/Qt5.12.10/5.12.10/gcc_64/lib
内核版本：umame -a
增加库路径：
gedit /etc/ld.so.conf
增加路径即可

自动化安装脚本
