How to install ORCHIDEE on an linux pc (Ubuntu or Fedora distribution)

This installation guide has been tested on a laptop computer using Ubuntu 12.04 version. Softwares used : gcc (C compiler), gfortran (Fortran 90 compiler), subversion (version control system), netcdf 3.6.3
Follow the steps and you will be able to compile and launch ORCHIDEE in sequential on a point to test it !

1.a Installing netcdf library (package installation) (not tested)

Now, netcdf is available as a package for linux distribution. For Ubuntu, a package exists. This installation was not tested, but it is OK, go to step 2 !

1.b Installing netcdf library (manual installation)

The most difficult part consists to install the netcdf library. The version chosen is netcdf 3.6.3 ; it is entirely sufficient for your laptop.

Download netcdf : Open a terminal and type the following command (> represents the prompt) to download netcdf 3.6.3 :

    >   wget http://www.unidata.ucar.edu/downloads/netcdf/ftp/netcdf-3.6.3.tar.gz

Extract the archive :

    >    tar -xvzf netcdf-3.6.3.tar.gz

A directory called netcdf-3.6.3 will be created. Go inside it :

    >    cd  netcdf-3.6.3

If you type ls, you will find :

    > ls
acinclude.m4  config.guess  configure     cxx      dods.m4   fortran     libsrc     Makefile.am  man4      ncdump  nc_test   README
aclocal.m4    config.h.in   configure.ac  cxx4     examples  INSTALL     libsrc4    Makefile.in  missing   ncgen   nc_test4  RELEASE_NOTES
compile       config.sub    COPYRIGHT     depcomp  f90       install-sh  ltmain.sh  man          ncdap.m4  nctest  nf_test   win32

Now focus on the script called configure. To know more about this script and the different options available, look at ​http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-install/Configure.html#Configure.
I execute this script like this :

      >  ./configure  --disable-largefile --disable-cxx

In my case, I deactivate the creation of large netcdf files (larger than 2 GB) with the option --disable-largefile. I also deactivate the creation of netcdf libraries for C++ because I don't need it. But to create netcdf libraries for FORTRAN, you have to create netcdf libraries for C. If you have a C compiler and a FORTRAN compiler, you will have no problems. Now you need to be root user. If you are on Ubuntu system (or Debian), type :

      >  sudo su

On Fedora :

      >  su

Enter your password then execute in the following order :

      > make

( compile netcdf on your computer.) Then

      > make check

( Test the buiding ) and finally the installation :

      > make install

If your installation was successful, the following message will appears :

+-------------------------------------------------------------+
| Congratulations! You have successfully installed netCDF!    |
|                                                             |
| CAUTION:                                                    |
|                                                             |
| If you have not already run "make check", then we strongly  |
| recommend you do so. It does not take very long.            |
|                                                             |
| Before using netCDF to store important data, test your      |
| build with "make check".                                    |
|                                                             |
| NetCDF is tested nightly on many platforms at Unidata       |
| but your platform is probably different in some ways.       |
|                                                             |
| If any tests fail, please see the netCDF web site:          |
| http://www.unidata.ucar.edu/software/netcdf/                |
|                                                             |
| NetCDF is developed and maintained at the Unidata Program   |
| Center. Unidata provides a broad array of data and software |
| tools for use in geoscience education and research.         |

+-------------------------------------------------------------+

After, you can delete the directory netcdf-3.6.3 (still in root) :

     >  rm -rf netcdf-3.6.3.tar.gz netcdf-3.6.3

2. Installing ORCHIDEE

After this hard task, you need to install the modipsl environment into MY_ORCHIDEE (you can change the name of this directory) :

      >  svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk MY_ORCHIDEE

Then go to :

      >  cd MY_ORCHIDEE/util

You can install a public version on your laptop. Execute :

      > ./model ORCHIDEE_TAG

If you are a developer of ORCHIDEE, you can download your own version with the script recup_my_ORCHIDEE (see SVN course for that). Nearly the end ! Edit AA_make.gdef and replace the following line by :

#-Q- gfortran  F_C = gfortran -c

by

#-Q- gfortran  F_C = gfortran -c -cpp

and execute the script called ins_make :

    >  ./ins_make -t gfortran

Then go to modeles/ORCHIDEE_OL :

    >  cd ../modeles/ORCHIDEE_OL

and finally compile :

   >  make; make teststomate; make forcesoil

CONGRATULATIONS, it's done !
