BuildRequires: g2clib-static
BuildRequires: openjpeg-devel

# a note on the build requirements:
# pygrib installation instructions mention these requirements:
#    $GRIBAPI_DIR, $JASPER_DIR, $OPENJPEG_DIR, $PNG_DIR and $ZLIB_DIR 
# (see https://jswhit.github.io/pygrib/docs/index.html)
#
# grib_api-devel is mentioned above.
# g2clib-devel is included in the pygrib sources, but has been removed
# to comply to Fedora policy, so has been added as requirement
# jasper-devel is BR by grib_api-devel
# libpng-devel and jasper-devel are BR for g2clib-devel
# jasper-devel BRs libjpeg-devel and others
# libpng-devel BRs zlib-devel
# However, pygrib does not need header files from these packages
# during the build, therefore no explicit BuildRequires is needed
# for jasper, openjpeg, png or zlib
#
# in addition python3-pyproj has been added as BR
# below since it is needed to run the test.py script in the check stage 

%global _description \
Cython wrapper to provide python interfaces to the grib library. \
 \
GRIB is the the World Meteorological Organization (WMO) standard for \
distributing gridded data. This module contains python interfaces for reading \
and writing GRIB data using the ECMWF GRIB API C library, and the NCEP GRIB2 \
C library, as well as command-line utilities for listing and re-packing GRIB \
files.
