= How to install ORCHIDEE with modipsl and libIGCM for offline use =

Here I describe how to install a version of ORCHIDEE created after the re-organization of driver sources, this means all versions of ORCHIDEE containg the src_driver directory. If the branch or personal version you want to use contains both ORCHIDEE and ORCHIDEE_OL directories, then you can extract using the script '''recup_my_ORCHIDEE'''. Otherwise if you have only ORCHIDEE directory, extract using the script '''model''' as below. The configuration files will then be the latest trunk version.


== Method 1 : for ORCHIDEE/trunk ==
To extract and compile the latest trunk version of ORCHIDEE and configuration files for offline simulations :
{{{
svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
cd modipsl/util
./model ORCHIDEE_trunk
cd ../modeles/ORCHIDEE/
gmake driver
}}}


== Method 2 : for branche other version on svn ==
If you want another version of ORCHIDEE, before compiling change the version of ORCHIDEE, in this case you will keep the configuration files from the trunk version : 
{{{
svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
cd modipsl/util
./model ORCHIDEE_trunk
cd ../modeles
rm -fr ORCHIDEE
svn co svn://forge.ipsl.jussieu.fr/orchidee/branches/xxxxxxx/ORCHIDEE ORCHIDEE     # or a copy from a local version of ORCHIDEE
cd ../util ; ./ins_make      # Create makefiles
cd ../modeles/ORCHIDEE
gmake driver
}}}

== Method 3 : for branche or other version on svn ==
Do as method 1 but modifiy the file mod.def to extract a specific version of ORCHIDEE. The file mod.def specifices all componentes to be extracted with the script model for each configuration predefined.
{{{
svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
cd modipsl/util
vi mod.def                  # Edit the line corresponding to extraction of ORCHIDEE sources for target ORCHIDEE_trunk

Change following line :
#-C- ORCHIDEE_trunk  trunk/ORCHIDEE                           HEAD   15 ORCHIDEE         modeles
into, with correct path to your branch or perso directory, HEAD can also be changed to a specific revision number :
#-C- ORCHIDEE_trunk  branches/mybranch/ORCHIDEE               HEAD   15 ORCHIDEE         modeles

./model ORCHIDEE_trunk
cd ../modeles/ORCHIDEE
gmake driver
}}}
