Getting the code
To download the code you can either check-out a working copy from git or download a tar file of the source from the download area.
Specific versions can then be checked out, e.g. R02-00-00 to get release version 2.0.0. We recommend using the most recently released tag. For example:
git clone -b R02-00-00 https://phab.hepforge.org/source/evtgen.gitAlternatively, do:
git clone https://phab.hepforge.org/source/evtgen.git cd evtgen git checkout R02-00-00
Alternatively, the download area contains gzipped tar files of the tagged versions.
In order to keep up to date with announcements of new releases etc. please subscribe to the evtgen-announce mailing list.
Compiling the code
Instructions for creating the EvtGen library can be found here.
There is also an example script that can be used to install EvtGen with HepMC3, Pythia, Photos and Tauola packages.
