Set ROOT Environment Variables: Windows

To set up your ROOT environment, create the following environment variables:

ROOTSYS=%GLAST_EXT%\ROOT\v5.20.00-gl3\vc8 HOME=[yourHomeDirectory, e.g., c:\] PATH=%ROOTSYS%\bin;%ROOTSYS%\lib;%PATH%;%HOME% TEMP=C:\Temp TMPDIR=C:\Temp

Notes:

• While GLAST Offline Software releases use a specific version of ROOT, this does
  not necessarily limit the user to running the same version of ROOT for analysis.

Caution: A specific version of any release of Glast software uses a specific version of ROOT; any and all documentation assumes that the appropriate version of ROOT is being used.

For version numbers used with a specific release of Glast software, see Glast Package and External Library Content.

• If you are not familiar with setting up the environment variables for your machine,
  refer as necessary to Set Environment Variables (Developers): Windows Desktop Installation.
