1 How to install HepMC on your laptop (Linux/Mac OSX) and link to Pythia
3 As of Pythia 8.175 support for older HepMC versions have been dropped,
4 so you have to use HepMC version 2.06 (or later), Here is an example
5 for HepMC 2.06.08 that works for me, but it comes with no guarantee.
7 1) Create a directory where you want to do the installation, e.g.
13 http://lcgapp.cern.ch/project/simu/HepMC/download
14 in a browser, scroll down to "HepMC 2.06.08" and pick the version relevant
15 for your platform from the list to the right.
17 3) In the pop-up menu pick "Save to file" and then the above hepmc directory.
18 You should now have the appropriate version in that directory,
19 e.g. HepMC-2.06.08-x86_64-mac106-gcc42-opt.tar.gz on a current Mac.
23 with "file" the name of the downloaded file. This will create a new directory,
24 e.g. x86_64-mac106-gcc42-opt/, where ready-to-use libraries can be found.
26 5) Now move to your pythia8175 (or later) directory and configure with
27 ./configure --with-hepmc=mypath/hepmc/newdir --with-hepmcversion=2.06.08
28 where "mypath" is the absolute path to the hepmc directory (use pwd if
29 in doubt) and "newdir" is the name of the new directory created in step 4.
30 (Re)compile with "make" (or "gmake") as usual.
32 6) Move to the examples subdirectory and do
35 Only one of them will work, depending on which shell you use, but the other
38 7) You should now be able to make and run e.g. main41 to produce HepMC
