After many times installation of lammps (intel compiler), here is my conclusion of easiest way to compile lammps. (lammps version: Feb 16, 2016, compiler version: intel XE 2016 update 1). cd to the src directory. (1) cd lib/meam vi Makefile.lammps.ifort change to: meam_SYSLIB = -lifcore -lsvml -liomp5 -limf meam_SYSPATH = -L/share/apps/intel/compilers_and_libraries_2016.1.150/linux/compiler/lib/intel64 make -f Makefile.ifort (2) cd ../reax make -f Makefile.ifort (3)cd ../poems make -f Makefile.icc (4) cd to ../../src make no-voronoi make yes-meam make yes-reax make yes-poems make yes-user-reaxc make yes-shock make yes-user-atc make yes-user-MISC ## make yes-user-quip make yes-user-sph make yes-user-eff make yes-user-phonon make yes-user-diffraction make yes-user-mgpt make yes-user-qmmm make yes-user-qtb make yes-user-smd make yes-user-smtbq make -j 8 ompi_icc done!
