#==========================================================================
#  Start of user-defined options. In some macro definitions below: "on" or
#  any other string means TRUE while blank (or spaces) is FALSE.
#==========================================================================
#
#  The CPP option defining a particular application is specified below.
#  See header file "ROMS/Include/cppdefs.h" for all available idealized
#  and realistic applications CPP flags. For example, to activate the
#  upwelling test case (UPWELLING) set:
#
#    ROMS_APPLICATION ?= UPWELLING
#
#  Notice that this makefile will include the associated application header
#  file, which is located either in the "ROMS/Include" or MY_HEADER_DIR
#  directory.  This makefile is designed to search in both directories.
#  The only constrain is that the application CPP option must be unique
#  and header file name is the lowercase value of ROMS_APPLICATION with
#  the .h extension. For example, the upwelling application includes the
#  "upwelling.h" header file.

ROMS_APPLICATION ?= UPWELLING

#  If application header files is not located in "ROMS/Include",
#  provide an alternate directory FULL PATH.

MY_HEADER_DIR ?=

#  If your application requires analytical expressions and they are
#  not located in "ROMS/Functionals", provide an alternate directory.
#  Notice that a set analytical expressions templates can be found in
#  "User/Functionals".
#
#  If applicable, also used this directory to place your customized
#  biology model header file (like fennel.h, nemuro.h, ecosim.h, etc).

MY_ANALYTICAL_DIR ?=

#  Sometimes it is desirable to activate one or more CPP options to
#  run different variants of the same application without modifying
#  its header file. If this is the case, specify such options here
#  using the -D syntax.  For example, to write time-averaged fields
#  set:
#
#    MY_CPP_FLAGS ?= -DAVERAGES
#

MY_CPP_FLAGS ?=

#  Activate debugging compiler options:

   USE_DEBUG ?=

#  If parallel applications, use at most one of these definitions
#  (leave both definitions blank in serial applications):

     USE_MPI ?=
  USE_OpenMP ?=

#  If distributed-memory, turn on compilation via the script "mpif90".
#  This is needed in some Linux operating systems. In some systems with
#  native MPI libraries the compilation does not require MPICH type
#  scripts. This macro is also convient when there are several fortran
#  compiliers (ifort, pgf90, pathf90) in the system that use mpif90.
#  In this, case the user need to select the desired compiler below and
#  turn on both USE_MPI and USE_MPIF90 macros.

  USE_MPIF90 ?=

#  If applicable, activate 64-bit compilation:

   USE_LARGE ?= on

#  If applicable, link with NetCDF-4 library. Notice that the NetCDF-4
#  library needs both the HDF5 and MPI libraries.

 USE_NETCDF4 ?=

#  We are going to include a file with all the settings that depend on
