Fresh ROOT installation --> Uninstall and then Install Root

[glitch401]

I have been trying to reinstall root from scratch.

I have followed up with discussions in this forum, such as :

How to uninstall the old root?

I want to install a new root .Please tell me how to uninstall the old root? Delete directly?

HOWTO Uninstall root?

Hi there, This might be a very naive question, but I have to ask it… I’ve been having problems with my root software. There are some basic functions or operations I cannot perform, and I’m almost sure it is because I did no install root in a proper way, so I want to do it again, from the very beginning. So, could you tell me how I can uninstall root? I think my problem was I installed it in my own $HOME (Ubuntu), and apparently I didn’t do a correct configurations procedure . Thanks a…

for the uninstallation process.
and deleted the directory mentioned in $ROOTSYS
removed the source path for ‘thisroot.sh’ from .bashrc
But still
while building fresh, I get an error, using cmake --build . --target install
pointing to the directory I had build root last

So is there some history file for root that I need to delete?

ROOT Version: 6.16.00
Platform: Ubuntu 18.04.2 LTS
Compiler: Not Provided

Seems like I have found a solution to the problem :

There is a file in the home dir (Ubuntu 18.04)
by the name : ‘.root_hist’

It should be deleted for complete uninstallation
followed by deletion of the built dir of root ,
and
removal of the line :
source <path/to/installation/thisroot.sh>

else there will be problems while reinstalling ROOT .

Cheers ,
Indranil.
