Here my hero lays the quest. No mere mortal is capable of building BeAGLE on his system and not everyone is able to run it on farms. But if you are still dare to try, here are the steps:
.. code ::
# Everything in CSH, you are doomed with your bash, zsh and others
setenv EICDIRECTORY /cvmfs/eic.opensciencegrid.org/x8664_sl7/MCEG/releases/env/EIC2021a/
setenv BEAGLESYS $EICDIRECTORY/PACKAGES/BeAGLE
setenv LHAPDF_DATA_PATH /cvmfs/sft.cern.ch/lcg/external/lhapdfsets/current
setenv LHAPDF_DATA_PATH ${LHAPDF_DATA_PATH}:${EICDIRECTORY}/share/LHAPDF/
setenv LHAPATH /cvmfs/sft.cern.ch/lcg/external/lhapdfsets/5.9.1/share/PDFsets
setenv LHAPDF5 /cvmfs/sft.cern.ch/lcg/external/lhapdfsets/5.9.1/share/PDFsets
setenv LD_LIBRARY_PATH $EICDIRECTORY/gcc-8.3/lib:$LD_LIBRARY_PATH
source /cvmfs/eic.opensciencegrid.org/gcc-8.3/opt/fun4all/core/gcc/8.3.0.1-0a5ad/x86_64-centos7/setup.csh
# (nice idea would be to add this to a single file to source. But for hardcore knights of keyboard and console
# it is adviced not to do so, memorize the commands and type them in manually every time to feel the glory)
# Now when you are equipped, let the quest begin:
mkdir My_Beagle_Quest # We name it awkwardly, so it is inline with everything else
cd My_Beagle_Quest
mkdir outForPythiaMode
cp $BEAGLESYS/nuclear.bin .
cp $BEAGLESYS/Examples/eD_18x135_Q2_1_10_y_0.01_0.95_test40k_Shd1_tau7_kt=ptfrag=0.32_shdfac=1.32.Jpsidiffnodecay.highpf.inp example.inp
cp $BEAGLESYS/Examples/eAt1dfJn .
$BEAGLESYS/BeAGLE < example.inp
#(!) Beware, example.inp has 1mil events to generate. You probably would like to decrease the number for the first run
