Recently I was learning qt. Since the files developed by qt have good portability, I want to compile in the liunx environment, but the error keeps
reporting and my mentality collapses : /home/zhangfakai/Qt5.14.1/5.14.1/gcc_64/include/QtGui /qopengl.h:141:
error: GL/gl.h: No such file or directory
解决方法
打开终端，执行两条指令
sudo apt-get install mesa-common-dev
sudo apt-get install libgl1-mesa-dev libglu1-mesa-dev
> 再运行就成功了
