bookworm version (bullseye, buster, stretch, squeeze)
ROOT is not part of Debian as of the last stable version 12 (bookworm). This is a quick installation guide from source that avoids debianization.
Download the source.
Install dependencies,
sudo apt-get install dpkg-dev cmake g++ gcc binutils git python3-dev python3-numpy libx11-dev libxpm-dev libxft-dev libxext-dev libgif-dev libtiff-dev libxml2-dev libbase-ocaml-dev
Define ROOT version,
export ROOTVER=6.28.04
Create a directory, for instance root, then untar the source,
mkdir root cd root tar -zxvf ../root_v$ROOTVER.source.tar.gz
Create a working directory,
mkdir build cd build
then configure, compile and install,
cmake ../root-$ROOTVER/ -DCMAKE_INSTALL_PREFIX=/usr/opt/root-$ROOTVER -Dgnuinstall=ON make -j4 sudo make install sudo ln -sfn /usr/opt/root-$ROOTVER /usr/opt/root
The option '-j' in make means the number of jobs to run simultaneously, in this case, four. In multi-core systems this reduces the compilation time considerably.
Update the dynamic linker,
sudo ldconfig
Define the ROOT environment variables in your .bashrc,
export ROOTSYS=/usr/opt/root export PATH=$PATH:$ROOTSYS/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib/root
If the system has many ROOT users, it may be advantageous to define these variables system-wide in /etc/bash.bashrc instead.
Run root at the terminal-emulator.
