# The following script can be used to compile one of the utilities
# program. Example of use :
# > compile concat
# > compile zrecast
## BUT first you must customize this script to your personal settings:
# 1) set up the correct environment; e.g. environment variable
#    NETCDF_HOME should point to your NetCDF distribution root directory
#    (and possibly you might need to "module load ..." a few things)
# 2) put the appropriate compiler and compiler options
#    in variables COMPILER and COMPILER_OPTIONS
# 3) Note that when you will run the executable, you might need to
#    also add the paths to the used libraries (e.g. $NETCDF_HOME/lib)
#    in environment variable LD_LIBRARY_PATH (most often the "module load ..."
#    command does this, so you should run it before running the executable) 

# Setup: (see at the end of this script for real world examples)
# possibly source some modules here and adapt variables below:
NETCDF_HOME="/path/to/the/NetCDF/root/directory"
COMPILER="gfortran"
COMPILER_OPTIONS="-O2"

# Compilation:
# (on some very old systems the Fortran NetCDF library is included
#  in the C library and "-lnetcdff" should be replaced with "-lnetcdf")

$COMPILER $COMPILER_OPTIONS $1.F90 \
-I$NETCDF_HOME/include \
-L$NETCDF_HOME/lib -lnetcdff \
-o $1.e

#
# Example of a setup on a simple Linux system where the netcdf library
# is in a personal location /home/myacount/netcdf directory:
# NETCDF_HOME=/home/myaccount/netcdf
# COMPILER="gfortran"
# COMPILER_OPTIONS="-O2"
# And of course the LD_LIBRARY_PATH environement variable should contain
# path "/home/myaccount/netcdf/lib" to be able to run the executable
#
# Example of a setup on LMD CentOS7 machines using gfortran and NetCDF 4.5:
# module purge
# module load gnu/7.2.0
# module load netcdf4/4.5.0-gfortran72
# NETCDF_HOME=/opt/netcdf45/gfortran72
# COMPILER="gfortran"
# COMPILER_OPTIONS="-O2"
# And of course modules above need be loaded before running the executable
#
# Example of a setup on the Ciclad cluster using ifort and NetCDF 4.3
# module purge
# module load intel/15.0.6.233
# module load netcdf4/4.3.3.1-ifort
# NETCDF_HOME=/opt/netcdf43/ifort
# COMPILER="ifort"
# COMPILER_OPTIONS="-O2 -ip"
# And of course modules above need be loaded before running the executable
#
# Example of a setup on the Occigen supercomputer
# module purge
# module load intel/17.0
# module load intelmpi/2017.0.098
# module load hdf5/1.8.17
# module load netcdf/4.4.0_fortran-4.4.2
# NETCDF_HOME=$NETCDFHOME
# COMPILER="ifort"
# COMPILER_OPTIONS="-O2 -ip"
