Hello ROOTers,
I tryed to install ROOT v6-20-04 with this official guide but doesn’t work:
## Building
Clone the repo
$ git clone https://github.com/root-project/root.git
$ cd root
$ git checkout -b v6-20-04 v6-20-04 (return in the folder previus cd root)
Make a directory for building
$ mkdir build
$ cd build
Run cmake and make
$ cmake -Dall=ON -Dfortran=ON ../root
$ make -j8
Setup and run ROOT
$ source bin/thisroot.sh
$ mousepad ~/.bashrc (add this line)
source /home/.../bin/thisroot.sh
alias root='root -l'
$ root
