When I try to link PROPhet to LAMMPS-16Mar18, I got the following errors.

force.o: In function LAMMPS_NS::Pair* LAMMPS_NS::Force::pair_creator<LAMMPS_NS::PairNN>(LAMMPS_NS::LAMMPS*)': /home/lammps-16Mar18/src/Obj_serial/../force.cpp:258: undefined reference to LAMMPS_NS::PairNN::PairNN(LAMMPS_NS::LAMMPS*)'

re-install PROPhet, or link PROPhet in the Makefile.package
(a) add -IPROPhet_DIR to PKG_INC
(b) add -LPROPhet_DIR to PKG_PATH
(c) add -lPROPhet_lammps to PKG_LIB
