1. Modify ./Lib/MCT

cd Lib/MCT
mkdir lib
mkdir include
./configure

- edit Makefile.conf
- set LIBDIR and INCLUDEDIR to */Lib/MCT/lib and */Lib/MCT/include
- change fortran compilers to ifort and icc

# INCLUDE PATHS (PREPEND INCLUDE FLAGS -I, -M or -p)
INCPATH         =  -I/nopt/nrel/apps/compilers/intel/2020.1.217/impi/2019.7.217/intel64/include

# COMPILER AND OS DEFINE FLAGS
DEFS            = -DSYSLINUX -DCPRINTEL

make 
make install

----

2. Modify coawst.bash

- set coawst application name, notice it should be capitalized
export COAWST_APPLICATION=SANDY_WW3_WRF

export MY_ROOT_DIR=/projects/oracle/branko/COAWST

export MCT_LIBDIR=${MY_ROOT_DIR}/Lib/MCT/lib
export MCT_INCDIR=${MY_ROOT_DIR}/Lib/MCT/include

- modify the following line, by removing the "slash"
#export   MY_ROMS_SRC=${MY_ROOT_DIR}/
export   MY_ROMS_SRC=${MY_ROOT_DIR}

export MY_HEADER_DIR=${MY_PROJECT_DIR}/Projects/<project name>
export MY_ANALYTICAL_DIR=${MY_PROJECT_DIR}/Projects/<project name>

export WWATCH3_NETCDF=NC4

- set WW3_SWITCH_FILE to appropriate switch file WW3/model/bin directory
export WW3_SWITCH_FILE=switch_sandy_WW3_WRF

- have prepend path under openmpi be blank so default mpif90 path is used for
  ifort alogn with:
which_MPI=openmpi

- turn off USE_LARGE and USE_NETCDF4 by setting

export USE_LARGE=
export USE_NETCDF4=

(Brian's note:  I needed to remove compiling WW3 util ww3_prtide from 
WW3/model/bin/make_MPI to get WW3 to compile.)

- run coawst.bash
% ./coawst.bash

- choose options 15 and 1 for WRF compilation


----

- If compiling WW3 for the first time then choose:
   - update WWATCH3_DIR (u)
   - update settings (y)
   - printer <enter>
   - FORTRAN compiler
   - add icc for C compiler
   - scratch space <enter>
   - source code (save)
   - listings (save)
   - new setting (y) [y - means OK]

-----

At this point the compilation will likely fail,
however, as Brian mentioned what is missing is just a few
modifications to the last linking step. 
That last step is included in the file:

goodcompile.ww3wrf.command

In this file -lnetcdff is added and the order of linked libraries is
modified in particular 

So, now all that is left to be done is to execute:

% ./goodcompile.ww3wrf.command


When successful, will get executable ‘coawstM’, along with real.exe, etc.

Notice that wrf.exe is not created, instead libwrflib.a is created.
