#
#  DESCRIPTION	: This script is used to compile all components needed for the ORCHIDEE offline drivers. The following components 
#                 will be compiled: IOIPSL, XIOS and ORCHIDEE.
#                 Default compilation is set up for the machines irene/TGCC, jean-zay/IDRIS, obelix/LSCE and ciclad and 
#                 climserv/IPSL. For other machines compiling option needs to be specified for each of the components. 
#                 The script first sources a arch.env file, from folder ARCH, containing modules needed for the current machine. 
#                 This means that the modules do not need to be sourced before starting the compilation. Output from compilation 
#                 are stored in a separate file out_compile_orchidee.date. 
#                 For help about the script, use: ./compile_orchidee_ol.sh -h

#
########################################################################

./compile_orchidee_ol.sh [Options] 

Options: 
  [-full]: full recompilation of all components 
  [-full_orch], [-full_xios]: recompile only orchidee or xios component
  [-arch XXX]: Force to use arch-XXX.fcm and arch-XXX.path files with specific compilation options for current platform. The files must be 
   available in modles/ORCHIDEE/arch, modeles/XIOS/arch and modeles/IOIPSL/arch folders. If the file config/ORCHIDEE_OL/ARCH/arch-XXX.env 
   exist, it'll be sourced in the beginning of this compilation script.
  [-debug], [-dev], [-prod](default): use compilation options for debug, dev or production mode, only one option can be used
  [-all_exec]: also compile other exectables than the drivers (testrouting, forcesoil and teststomate)
  [-without_xios]: no compilation or linking to XIOS. Default compilation is done with XIOS
  [-parallel seq] / [-parallel mpi](default): compile without MPI for use in sequential mode / with MPI (default). 
   When using [-parallel seq], [-without_xios] must as well be set.
  [-netcdf_lib_seq]: option to tell XIOS that linking with netcdf4 sequential library will be used instead of default netcdf4 parallel library


Example 1: Default compilation of ORCHIDEE with XIOS and IOIPSL
./compile_orchidee_ol.sh

Example 2: Compile in debug mode
./compile_orchidee_ol.sh -debug

Example 3: Default compilation with full recompilation of all components
./compile_orchidee_ol.sh -full

Example 4: No compilation or linking to XIOS
./compile_orchidee_ol.sh -without_xios

Example 5: Compilation without MPI for sequential use only. Note that XIOS must be deactivated as well.
./compile_orchidee_ol.sh -parallel seq -without_xios
