There are different predefined configurations in modipsl containing LMDZ and ORCHIDEE. Different configurations are adapted to different versions of the modeles.

See also the list of condigurations under "LMDZOR" section in ​http://forge.ipsl.jussieu.fr/igcmg_doc/wiki/Doc/Config

• LMDZOR_v6.3_work : Working configuration which uses the latest revision of ORCHIDEE/trunk (after nitrogen cycle was introduced). The version of LMDZ is currently the same as in LMDZOR_v6.1.X LMDZ6/branches/IPSLCM6.0.15. Compilation is the same fr this configuration than for LMDZOR_v6.2_work, only ORCHIDEE version differs between both.
  

• LMDZOR_v6.2_work : Working configuration which uses ORCHIDEE_2_2 and LMDZ6/trunk. Note that this configuration has a new way to compile and it is only adapted to be used at TGCC/irene for the moment. Please contact the referent person before first use.
  

• LMDZOR_v6.1.X : Configurations used for CMIP6 production simulations using stable versions of LMDZ and tag ORCHDIEE_2_0, ​read more about LMDZOR_v6. Take the highest number for X (currently LMDZOR_v6.1.10).
  

• (Obsolete LMDZOR_v5 : Contains a trunk version 2076 of LMDZ5 and ORCHIDEE tagged version 1.9.5 (CMIP5 version))
  

• (Obsolete LMDZOR_v5.2 : Contains the same LMDZ5 as LMDZOR_v5 and revision 2247 on the trunk of ORCHIDEE)

Usage of these configurations are covered by the igcmg_doc documentation : ​https://forge.ipsl.jussieu.fr/igcmg_doc/wiki/Doc

Quick summary for installing LMDZOR_v6.1.10

svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
cd modipsl/util
./model LMDZOR_v6.1.10
cd ../config/LMDZOR_v6
gmake

Install a branch ORCHIDEE with LMDZ

If you want to extract a branch of ORCHIDEE instead of the trunk, first you need to know if the branch is updated or created after the nitrogen cycle was introduced in the trunk, ORCHIDEE/trunk revision 5639. If this is the case, then use the configuration LMDZOR_v6.3_work otherwise use one of the LMDZOR_v6.1.X configurations. See here an example for extraction and compiling of ORCHIDEE-MICT with the default LMDZ6 version. In the example below you can change ORCHIDEE-MICT into another branch name.

svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl
cd modipsl/util
vi mod.def   

    Modifiy the line 
#-C- LMDZOR_v6.1.10  tags/ORCHIDEE_2_0/ORCHIDEE         5661    14   ORCHIDEE     modeles
    into
#-C- LMDZOR_v6.1.10  branches/ORCHIDEE-MICT/ORCHIDEE    HEAD    14   ORCHIDEE     modeles


./model LMDZOR_v6.1.10
cd ../config/LMDZOR_v6
gmake
