Example for setting up ROOT from CVMFS
. /cvmfs/sft.cern.ch/lcg/app/releases/ROOT/6.22.06/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 v6-22-06 v6-22-06
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).
