makeorchidee_fcm [Options] 

[ -parallel|-p PARALLEL_TYPE ] : activate parallelization with 3 options : 
    PARALLEL_TYPE =
    ( mpi | MPI )  : use Message Passing Interface standard
    ( omp | OMP )  : use OpenMP standard
    ( mpi_omp | MPI_OMP ) : use both MPI and OpenMP

[ -driver ] : compilation of ORCHIDEE driver if equal TRUE

[ -a|-arch ARCHitecture ] : if TRUE, change architecture for ARCHitecture

[ -prod ] : compilation for production (all optimization)

[ -dev ] : compilation for development (low optimization and -g)

[ -d|-debug ] : compilation for debugging (no optmization and all debug options)

[-fcm_path path]           : path for fcm (default: the default fcm path in environment)

[ -doc ] : generate documentation with Doxygen
