OpenIFS 38r1 and 40r1v1 fails with ecCodes

OpenIFS 38r1 (all versions) and 40r1v1 need a small code change to work with the ECMWF ecCodes library. This is because of the use of a deprecated grib related subroutine that was replaced in ecCodes.

The compilation will fail with a message similar to:

[FAIL]  CALL GRIB_NEW_FROM_TEMPLATE(KHANDLE,TRIM(CDNAME),STATUS=IRET)
[FAIL] Error: Keyword argument requires explicit interface for procedure ‘grib_new_from_template’ at (1)
[FAIL] compile    0.0 ! grib_api_interface.o <- ifsaux/module/grib_api_interface.F90

For these versions, make the following change to the code.

Edit ifsaux/module/grib_api_interface.F90

Change line 671 (in subroutine IGRIB_NEW_FROM_TEMPLATE) from:

CALL GRIB_NEW_FROM_TEMPLATE(KHANDLE,TRIM(CDNAME),STATUS=IRET)

to

CALL GRIB_NEW_FROM_SAMPLES(KHANDLE,TRIM(CDNAME),STATUS=IRET)

This change has been tested against grib-api and eccodes libraries and gives bit identical results.

 

OpenIFS 40r1 fails with grib_api less than 1.11.0

The minimum version of the grib_api library for OpenIFS 40r1 is 1.11.0.

If you see the following error when compiling, please upgrade your version of grib-api / ecCodes:

Error: There is no specific subroutine for the generic 'grib_write_bytes'
