# Author : Laurent Fairhead et Frédéric Hourdin
# Usage  : install_lmdz.sh -help
#
# bash installation script of the LMDZ model on different computer types :
# Linux PC, "mesocentre" (IPSL-UPMC, IPSL-X), super-computer (IDRIS)
#
# The model is downloaded in the following directory tree
# $MODEL/modipsl/modeles/...
# using the "modipsl" infrastructure created by the "IPSL"
# for coupled (atmosphere/ocean/vegetation/chemistry) climate modeling
# activities.
# Here we only download atmospheric (LMDZ) and vegetation (ORCHIDEE)
# components.
#
# The sources of the models can be found in the "modeles" directory.
# In the present case, LMDZ, ORCHIDEE, and IOIPSL or XIOS (handling of
# input-outputs using the NetCDF library).
#
# The script downloads various source files (including a version of NetCDF)
# and utilities, compiles the model, and runs a test simulation in a
# minimal configuration.
#
# Prerequisites : gfortran, bash or ksh, wget, gunzip, tar, ...
#
# Modif 18/11/2011
#    changes for option real 8.
#      We compile with -r8 (or equivalent) and -DNC_DOUBLE for the GCM
#      but with -r4 for netcdf. Variable real must be set to
#      r4 or r8 at the beginning of the script below.

#          Avec orchidee2.1, on va compiler LMDZ avec le cle cpp ORCHIDEE_NOLIC. On ne va donc pas prendre en compte les avancements fait dans le trunk qui permet que les fractions lic soitent traité par ORCHIDEE. Ca marche très bien sans cela puisque dans tout façon c'est en cours de développement et ce n'est pas activé par default. En fait on devrait compiler le trunk avec -v orchideetrunk mais avec landice_opt>2, ce qui ne change rien par rapport à orchidee2.1
#Si on voudrait activer landice_opt=2 , il faut compiler avec -v orchideetrunk.
