Hi experts!
I’m a root beginner.
How can i access to directory $ROOTSYS ?
I typed cd $ROOTSYS but there’s no reaction. After i typed pwd, then i located in /home/usr
So $ROOTYS is not defined in your case. You should define it. The simplest is to “source” the script file “thisroot.sh” sitting next to the root.exe module. You "cd’ in that folder (where root.exe is) and type:
$ source thisroot.sh
Of course it is recommended to put that command in your .profile file in order to have it executed each time you start a new terminal.
I looked at the route manual and followed it. However, there was a lot of trial and error in the download process. So, there are multiple root folders.
