# Short explanation of the compiler and the linking library FLAGS:
#
# the -L is immediately followed by the library-path, thereafter each library libX.a, libY.a, etc are
# separately listed as -lX -lY etc. 
#
#   Compiler flags                    Specification
#
#  -O3                                is the  optimalisation flag (causing faster executables)
#  -J${MOD_PATH}                      is the  path of the directory with all the *.mod files
#  -Wall                              is the  optimalisation flag
#  -ffree-line-length-none            is the -ffree-line-length-n, sets n columns after which characters are ignored, -ffree-line-length-none = -ffree-line-length-0
#  -fbounds-check                     is the  flag for checking array boundaries
#  -fcheck-array-temporaries          is the  flag for checking array substitution
#  -p                                 is the  flag for profiling with gmon (better to turn off if using valgrind)
#  -g                                 is the  flag which should be turned on if the valgrind debugger is used
#
# Linking flags of libraries:
#  -L${NETCDF_PATH}/lib               is the  netcdf library path
#  -lnetcdf                           is the  netcdf c library
#  -lnetcdff                          is the  netcdf fortran library


# Other gfortran compiler flags (for better checks with compilation):
# -Wuninitialized -O -ftrapv -fno-automatic -fimplicit-none

# Linking the fortran compiler with  -g -w  for debugging with valgrind but omit profiling while using valgrind:
# valgrind --log-file=log-valgrind.bug --tool=memcheck --leak-check=yes --show-reachable=yes --num-callers=20 --track-fds=yes ./src/oblimap_par_gcm_to_im_program config-files/oblimap/ccsm-to-im/config_oblimap_ccsm_to_im_greenland
