# To compile and link LAMMPS to the reax library generated by this Makefile,
# you need to first install the reax package (make yes-reax), after which the
# file Makefile.package should look something like:

# PKG_INC =  -I../../lib/reax
# PKG_PATH = -L../../lib/reax
# PKG_LIB =  -lreax 

# PKG_SYSPATH = $(reax_SYSPATH) 
# PKG_SYSLIB =  $(reax_SYSLIB) 
 
# The reax_SYSPATH and reax_SYSLIB variables contain compiler options
# giving the paths of needed FORTRAN libraries, and their names, respectively
#
# For Makefile.gfortran, try
#
# reax_SYSPATH = -L/usr/lib
# reax_SYSLIB = -lgfortran
