Get PYTHIA and install it

wget https://pythia.org/download/pythia82/pythia8235.tgz
tar zxf pythia8235.tgz
mv pythia8235.tgz pythia8235
cd pythia8235
./configure
make -j
make install
cd ..

Get the Eigen library

wget -O eigen.tar.bz2 https://gitlab.com/libeigen/eigen/-/archive/3.3.9/eigen-3.3.9.tar.bz2
tar jxf eigen.tar.bz2
mv eigen-3.3.9 eigen
mv eigen.tar.bz2 eigen/

Define different environment variables

You can create a file "prepare.sh" with proper links to the different libraries

#emacs prepare.sh
#vi prepare.sh

Content of "prepare.sh":

export EIGEN_INSTALL_DIR=`readlink -f ./eigen`
export EIGEN3_ROOT=`readlink -f ./eigen`
export GSL=$(gsl-config --prefix)
export GSL_HOME=$(gsl-config --prefix)
export GSL_ROOT_DIR=$(gsl-config --prefix)
export JETSCAPE_DIR=`readlink -f .`
export SMASH_DIR=${JETSCAPE_DIR}/external_packages/smash/smash_code
export PYTHIAINSTALLDIR=`readlink -f .`
export PYTHIA8DIR=${PYTHIAINSTALLDIR}/pythia8235
export PYTHIA8_ROOT_DIR=${PYTHIAINSTALLDIR}/pythia8235
export CC=gcc
export CXX=g++
export OpenMP_CXX=g++

---

Then run:

source prepare.sh
