1. Look at the pre-requisites on the CERN website
- For ubuntu, you need to do:
sudo apt-get install dpkg-dev cmake g++ gcc binutils libx11-dev libxpm-dev libxft-dev libxext-dev python3 libssl-dev
- and I strongly suggest installing the optionnal packages too:
sudo apt-get install gfortran libpcre3-dev xlibmesa-glu-dev libglew-dev libftgl-dev libmysqlclient-dev libfftw3-dev libcfitsio-dev graphviz-dev libavahi-compat-libdnssd-dev libldap2-dev python3-dev python3-numpy libxml2-dev libkrb5-dev libgsl0-dev qtwebengine5-dev nlohmann-json3-dev
2. Download the latest release from the CERN download page
- a. Click on the latest release
- b. Under Binary distributions (ie already compiled for a specific platform), download the tar.gz file appropriate to your platform
- To get your ubuntu version, type cat /etc/lsb-release in a terminal
- To get you gcc version, type gcc --version. Your release number need to be the mentioned one (whatever the minor version is, ie like 4.8[.1]).
3. Extract the compressed tarball:
tar xzvf root_v6.30.06.Linux-ubuntu22.04-x86_64-gcc11.4.tar.gz
- This should create a directory called root. You can move this directory wherever you want.
4. To use RooT, you need to source the script thisroot.sh available in root/bin.
- To make root available anytime from your terminal, edit your .bashrc file, and add the following line at the end (replace ~/root with where you put the extracted directory):
# Enabling RooT source ~/root/bin/thisroot.sh
Et Voila !
