Now CMake developer team in Kitware Inc provides APT repositiory. on Ubuntu, these libs must be installed: sudo apt install pkg-config curl git build-essential libssl-dev libclang-dev cmake. Please be aware this assumes that you’ve already installed the required packages listed here under the Ubuntu section, I’ve neglected to mention this so far because I’m assuming you have these packages already from attempting to compile ROOT yourself, but it could be worth running the provided apt install commands just to make sure.Edit: As GNUton has pointed out, the following only works on Ubuntu. bashrc file, so that it’s run on every terminal invocation automatically. You’d need to run the source command every time you open a new terminal unless you were to use an approach such as adding it to the. This sets up the root environment, after you’ve run source bin/thisroot.sh, you can run root in the terminal and it’ll work, you can also run python where import ROOT would then work. You don’t need the source distribution with the precompiled download, you need to extract the contents of the binary archives, and then run the command source bin/thisroot.sh, you may need to change the exact path to thisroot.sh depending on where you’ve actually placed the extracted ROOT folder and your current working directory, but I presume you’ll be ok with working out the exact paths if needs be. There’s also a Conda package available that would likely be preferable to compiling your own versions too, which doesn’t have the same integration issues as the snap has but has a slightly harder setup, if you end up using ROOT in more complex ways in the future (e.g, maybe by linking ROOT and Geant4 together at a binary level), this is a very good option too. This is also available in the other builds but might require additional setup. With the Snap, it might also be easier for yourself with getting started by trying to run root -notebook, which would open a browser environment with Jupyter Notebooks for running ROOT interactively and might be easier to get accustomed to. GCCC is the standard C/C++ compiler, but you can also use Clang/LLVM. Once you have logged into your Ubuntu instance, run these commands to update your system. Connect by SSH using the credentials we emailed you. Sign in to your system or register a newly created one by logging in to your VPSie account. Step 1: Configure the VPSie cloud server. If you wish to use pyroot with the ROOT snap however, you need to run pyroot in the terminal rather than python. In Ubuntu, you can install these tools with the package build-essential. We will now look at how to install CMake on Ubuntu 20. For that, you can just run sudo snap install root-framework in the terminal, root will then by instantly available to you without requiring you run the source command, and it’ll also be added to your start menu. Once downloaded, you’d need to extract the archive (Which should be doable either graphically or with tar xf archive_ in the terminal), and each time you need to use root, you’d need to source the thisroot.sh file in the terminal which would make root and its other commands available to use.Īlternatively, I’d recommend trying the Snap package which is provided by myself, and is focused more on use cases like yourself where you just want a usable version of ROOT with minimum configuration and don’t need to consider integrating it with other projects in complex ways. You can take a look at the recent releases here and download a copy for Ubuntu 20.04. Officially, ROOT provides precompiled versions for Ubuntu 20.04. Assuming your teacher doesn’t have special requirements for ROOT, the usual advice would be to not bother compiling your own version and to resort to the precompiled binaries provided by ROOT & the community.
