Installation:
tar xvf ggrib.tar
cd ggrib
make -f ggrib.make
The TAR-file includes an SGI binary of ggrib, which makes compilation unnecessary for those fortunate owners of SGI's.
The library gribw must be compiled in advance using gribwlib.make.
This software along with the other files listed in ggrib.make
are all contained in the tape archive gribw.tar found at ftp://wesley.wwb.noaa.gov/pub/gribw.
