19990506: LDM - dcgrib errors with ETA data



Michael,

Devin's problems were for something else- in particular for
projections such as mrf grid #201 that had been defined in
patches that they did not download. 

The grid #211 projection has always been supported, so if
you are having trouble with the ETA on grid Q, you should
send me a copy of your pqact.conf entries. From your
error messges before, the #207 alaskan grids were being 
sent to the decoder which signifies that the pattern was not
restricting the grids to only Q.

You can always download gempak updates from the gbuddy account
using the password XXXXXX, host ftp.unidata.ucar.edu.
You will find the lastest dcgrib code in:
~gbuddy/nawips-5.4/patches/dcgrib*tar.Z.

To install the dcgrib code:

download the tarfile to your $NAWIPS directory and unpack with
zcat dcgrib.tar.Z | tar xvf -

The build dcgrib with:
cd $NAWIPS/unidata/ldmbridge/dcgrib
make clean
make all
make install
make clean
