19991230: Garp 2.1 update, gdthgt update

Gempak Users,

COMET has provided a Garp 2.1 release which addresses some
remaining Y2K issues with that program. I have also updated
gdthgt for grid files that span the year end period.

The patch has been placed in the ~gbuddy/nawips-5.4/patches
directory as gempak5.4_patch14.tar.gz

Before installing this patch, you may want to move your current
$NAWIPS/garp tree to $NAWIPS/garp2.02 so that you can refer to
settings in your $GARPHOME/config/Garp_defaults file for your
data directory locations and dataset names (model keys, names etc).

**Note that this patch assumes that you have the current distribution
from ~gbuddy/nawips-5.4/gempak54upc_pl12.tar.gz


The instructions for installing this patch are as follows:

0) in $NAWIPS, move your current garp tree

        mv garp garp2.02

1) download the compressed tar file to your local $NAWIPS directory

2) unpack the tar file with the command:
        gunzip -c gempak5.4_patch14.tar.gz | tar xvf -

3) Rebuild updated gemlib routines

        cd $GEMPAKHOME/source/gemlib/tg
        make clean
        make all
        make clean

        cd $GEMPAKHOME/source/gemlib/ti
        make clean
        make all
        make clean

4) Build an updated version of gdthgt (also used by Garp!!!)

        cd $GEMPAKHOME/source/programs/gd/gdthgt
        make clean
        make all
        make install
        make clean

5) Build and install Garp 2.1

        cd $GARPHOME
        make all
        make install
        make clean


It is very important that you follow the above steps in order
since the update of garp relies on the gdthgt library and the
updated gemlib routines!

I will be updating the complete distribution tarfile tomorrow.
I will also update the Linux and Solarix x86 binary distribution
tarfiles tomorrow (12/31/1999).

Without this patch, Garp2.02 will display incorrect forecast time
labels on the generated maps and gdthgt will not display labels
for time periods which run over the year end.

Garp 2.1 will display time selction widgets using 4 digit years
in the selection boxes.
