Compile NEMO

generic example : ./makenemo -n MY_CONFIG -j 6 -m MY_ENV

• Replace -n MY_CONFIG by names you find in NEMO/tests prefixed with -a or NEMO/cfgs prefixed with -r.
• Replace MY_ENV by linux_gfortran or by any name you chose when you created your arch file.

  # Let's go !
  cd NEMO
  # generic example : ./makenemo -n MY_CONFIG -j 6 -m MY_ENV 
  ./makenemo -h
  # compile ORCA2 configuration in the preset environment
  ./makenemo -r ORCA2_ICE_PISCES -j 6 -m linux_gfortran
  # compile CANAL configuration in the preset environment
  ./makenemo -a CANAL -j 6 -m linux_gfortran
