IntroductionThe ECMWF grib_api software library provides a set of functions/subroutines and command line tools for encoding and decoding WMO FM-92 GRIB edition 1 and edition 2 messages. The OpenIFS model uses GRIB for its input and output files. The grib_api software library must be build and installed before you try to build OpenIFS on your system. Although you may have a version of grib_api on your system already that would most likely work, it is recommended that you build and install grib-api yourself to ensure the same compiler and compiler version is used. Otherwise you may see error messages about conflicting module versions when compiling OpenIFS. For more information about grib_api and to download it please visit the grib_api website. |
