By default the program makes use of the LHAPDF library, to build LHAPDF:
wget http://www.hepforge.org/archive/lhapdf/LHAPDF-6.X.Y.tar.gz -O- | tar xz
cd LHAPDF-6.X.Y
./configure --prefix=$PWD/../local
make -j2 && make install
cd ..
After, add the following lines to the shell (bash) login script:
export LHAPDFSYS=/yourpath/LHAPDF-X.Y.Z
export PATH=${PATH}:${LHAPDFSYS}/bin
LD LIBRARY PATH=${LD LIBRARY PATH}:${LHAPDFSYS}/lib
To compile and to run SuperChic2:
make
cd bin/
./init < input.DAT
./superchic < input.DAT
