The Fortran makefile for calc_etadot

The Fortran program calc_etadot will be compiled during the installation process to produce the executable called calc_etadot.

Flex_extract includes several makefiles which can be found in the directory flex_extract_vX.X/Source/Fortran, where vX.X should be substituted by the current flex_extract version number. A list of these makefiles is shown below:

Remote/Gateway mode:
Files to be used as they are!
makefile_ecgate: For use on ECMWF’s server ecgate.
makefile_cray: For use on ECMWF’s server cca/ccb.
Local mode
It is necessary to adapt ECCODES_INCLUDE_DIR and ECCODES_LIB if they don’t correspond to the standard paths pre-set in the makefiles.
makefile_fast: For use with the gfortran compiler and optimisation mode.
makefile_debug: For use with the gfortran compiler and debugging mode. Primarily for developers.

If you want to use another compiler than gfortran locally, you can still take makefile_fast, and adapt everything that is compiler-specific in this file.

For instructions on how to adapt the makefile (local application mode only), please see Local installation.
