The makelmdz_fcm script to compile LMDZ
The makelmdz_fcm script is the bash script that you use to compile LMDZ. This is where one sets various options (e.g which physics package to compile the model with, what grid resolution to use, etc.).
To list available options, run "makelmdz_fcm -h", which should return something like:
Usage :
makelmdz_fcm [options] -arch nom_arch exec
[-h] : brief help
[-d [[IMx]JMx]LM] : IM, JM, LM are the dimensions in x, y, z (default: 96x72x19)
[-p PHYS] : set of physical parametrizations (in libf/phyPHYS), (default: lmd)
[-prod / -dev / -debug] : compilation mode production (default) / developement / debug
[-c false/MPI1/OMCT] : coupling with ocean model : MPI1/OMCT/false (default: false)
[-v false/orchidee2.0/orchidee1.9/true] : version of the vegetation model to include (default: false)
false : no vegetation model
orchidee2.1 : compile using ORCHIDEE 2.1 (or more recent version)
orchidee2.0 : compile using ORCHIDEE 2.0
orchidee1.9 : compile using ORCHIDEE up to the version including OpenMP in ORCHIDEE : tag 1.9-1.9.5(version AR5)-1.9.6
true : (obsolete; for backward compatibility) use ORCHIDEE tag 1.9-1.9.6
[-chimie INCA/false] : with INCA chemistry model or without (default: false)

[-ext_src path] : path to an additional set of routines to compile with the model
[-arch_path path] : path to architecture files (default: arch)
-arch nom_arch : target architecture
exec : executable to build
The user must at the very least provide the name of the executable (typically "gcm") and the mandatory option "-arch" with the target architecture name (e.g. "local" or "gfortran_CICLAD").
Some extra info about various makelmdz_fcm options
-d IMxJMxLM
As LMDZ works on a fixed grid (set when compiling), option "-d" is also almost always used to specify the number of grid points iimxjjmxlllm (where iim is the number of points along longitude, jjm is the number of points along latitude and llm the number of atmospheric layers).
If compiling the 1D model, then only the number of layers (llm) needs be specified, e.g. -d 78 to compile lmdz1d.
-j n
With this option one can speed up compilation by letting make compile simultaneously (and if possible) up to n routines in parallel (note that this "parallel compilation" has nothing to do with the code being compiled for serial or parallel use as specified via option -parallel ...). In practice using -j 8 or -j 4 works well.
-parallel none/mpi/omp/mpi_omp
This option is to specify whether the model should be compiled in serial mode (default) or in parallel using MPI (mpi) only, or using OpenMP (omp) only, or both MPI and OpenMP (mpi_omp).
In practice, one most often needs to run in parallel and using both MPI and OpenMP, so -parallel mpi_omp is advised.
-io ioipsl/mix/xios
This option specifies which IO (Input/Output) library is going to be used by the model. Default is -io ioipsl, which is becoming depreciated for the GCM but mandatory for the 1D model. Note that when compiling with XIOS: -io xios on still needs to also use the IOIPSL library (which handles the reading of the run.def and companion files).
-full
Impose a full cleanup (i.e. removing past object and library files) to ensure recompiling the model from scratch.
