Example for setting up ROOT from CVMFS

. /cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.24.02/x86_64-centos7-gcc48-opt/bin/thisroot.sh

Git

The entire ROOT source can be obtained from our public Git repository:

git clone https://github.com/root-project/root.git

The release specific tag can be obtained using:

cd root
git checkout -b v6-24-02 v6-24-02

Windows

Windows 10/7/… are supported. We offer two packaging types:

  • exe: a regular Windows installer package also setting up the required environment variables. With uninstall via “Control Panel” / “Add or Remove Programs”. Simply download and start. You can double-click ROOT to run it; ROOT files get registered with Windows.
  • tar: unpack e.g. with 7zip. Start ROOT in a Microsoft Visual Studio Prompt (in Start / Programs / Microsoft Visual Studio / Tools). If you installed ROOT to C:\root then call C:\root\bin\thisroot.bat before using ROOT to set up required environment variables.

Important installation notes

  • You must download the binary built with the exact same version of Visual Studio than the one installed on your system.
  • Do not untar in a directory with a name containing blank characters.
  • Take the release version if performance matters.
  • If you want to debug your code you need the ROOT debug build (you cannot mix release / debug builds due to a Microsoft restriction).
