# Instructions to compile INTERPOLATE.EXE
# This can be run a s a shell script / batch file in the interpolate directory
# Switches used:
# -dbl     must be used. Inverse Distance weighting does not# work well when very
#          near a know data point unless double precision is used.
# -nfix    free format code is used, fixed format code works with this option
# -in      implicit none insures all variables are expilcitly declared
# -trap    traps for real operation numerical errors
#          d - traps for divide-by-zero
#          i - traps for invalid operation
#          o - traps for numerical overflow
# -ap      protects arithmetic precision by always reading values from memory for all optimization levels
# -o2      maximum optimization level

# Alternately, the gfortran install looks like:

gfortran -static -fdefault-real-8 -ffree-form -fimplicit-none -ffpe-trap=zero,invalid,overflow -O2 -o interpolate interpolate.f95 idfind.f95 mirroring.f95 polysizing.f95 readpoly.f95 stripack.for trarcs.for vrout.for

And for INTERP_WDB

gfortran -static -fdefault-real-8 -ffree-form -fimplicit-none -ffpe-trap=zero,invalid,overflow -O2 -o interp_wdb interp_wdb.f95 stripack.for
