Dear ROOT users, I am installing ROOT with gcc7.5.0 on ubuntu18 and the following error occurred.
There are more errors later but I think this ‘incomplete type’ is the cause. I can post full error log if necessary.
I have installed ROOT on this computer before, I’m actually reinstalling. And my copy of ROOT source code works fine on another computer.
Also, I encountered ‘redefination error’ when I build ROOT without ‘-j4’.
I guess there’s something wrong with my complier, but I don’t know where to start.
Thanks in advance.
