At times we need to build a new version of the skimmer, or build a version for a particular OS or version of ROOT. Documentation concerning the skimmer is available in our Confluence pages here:

The instructions here differ somewhat from what is written in the FermiGuide.

In the bin directory of the skimmer distribution, you will see two scripts: make_fermi and make_tskim.
Note: Some earlier versions of the skimmer may have a script named make_skimmer in place of the more recent make_fermi script.
make_fermi will attempt to build the skimmer for both RHEL3 and RHEL4-32 using a variety of versions of ROOT. We use this script if this is a fresh installation of a version of the skimmer. There is no set up required to use this script. Just run make_fermi and the skimmer will be built.
