Do I have to build GOTM and 0d drivers separately before building fabm?

[tongyaopu]

Here is my understanding from the wiki page. I want to know if there is anything redundant.

I am not comfortable with how the directory is structured with my method:
src/fabm, src/fabm/src/drivers/gotm, src/fabm/src/drivers/0d, src/gotm for the source file
build/fabm, build/fabm-0d, build/fabm-0d/fabm, build/gotm for the build file
local/fabm/0d, local/gotm for the executables

Does 0d driver belong to fabm? or should 0d and gotm be separated from fabm?

My building and compiling steps:

FABMDIR="~/src/fabm" 	# Path to FABM source code
GOTMDIR="~/src/GOTM6" 	# Path to GOTM source code 
compiler="/opt/homebrew/bin/gfortran" 	# fortran compiler on this computer


# >>>> build and install python driver >>>>

# >>>> build and install GOTM >>>>

It will depend on what you need. This compiles and install pyfabm, which you need if you want to use FABM from Python:

# >>>> build and install python driver >>>>
mkdir -p ~/build/python-fabm
cd ~/build/python-fabm
cmake $FABMDIR/src/drivers/python
make install

This compiles and installs the 1D GOTM water column model, with FABM integrated:

# >>>> build and install GOTM >>>>
mkdir -p ~/build/GOTM && cd ~/build/GOTM
cmake ~/src/gotm6 -DCMAKE_Fortran_COMPILER=$compiler
make install

And this compiles and installs the 0d FABM box model:

# >>>> build and install FABM-0d >>>>
mkdir -p ~/build/fabm-0d && cd ~/build/fabm-0d
cmake $FABMDIR/src/drivers/0d -DGOTM_BASE=~/src/GOTM6 -DCMAKE_Fortran_COMPILER=/opt/homebrew/bin/gfortran 
make install

All of these have their uses, but you're unlikely to need them all at once.

The last snippet only compiles the FABM library for different hosts and does not serve a purpose as far as I can see, since the above hosts all already have FABM integrated:

# >>>> compile with FABM? >>>
cmake $FABMDIR -DCMAKE_FORTRAN_COMPILER=$compiler -DFABM_HOST=GOTM
cmake $FABMDIR -DCMAKE_FORTRAN_COMPILER=$compiler -DFABM_HOST=0d -DGOTM_BASE=$GOTMDIR 
cmake $FABMDIR -DCMAKE_FORTRAN_COMPILER=$compiler -DFABM_HOST=python
make install
