The following error occurred when graphically configuring the Linux 4.19 kernel on my Ubuntu 18.04. It was
solved after running the following command. Mark it here.
sudo apt-get install qttools5-dev
If there are still problems with make xconfig, then adding sudo
will still cause problems. After checking, the following blog helped me
https://blog.csdn.net/qq_41634294/article/details/89409782The
solution is :
sudo vi /etc/environment
Add at the end
QT_X11_NO_MITSHM=1
After saving,
everything is normal after running source /etc/environment. So far, only these two problems have been found.
