[GEMPAK #WFY-237676]: 20201007: Gempak

Hi Gyorgyi,

Ouch!

re:
> I already updated one using your tar file, and it was easy. I am grateful
> for that.

I found out this morning that the procedure that I listed in my previous
email was not fully correct (unless the build was/is new).

Here is what I wrote before:

<as 'gempak'>
cd ~gempak/NAWIPS
wget ftp.unidata.ucar.edu:pub/gempak/Y2K21/gempak_y2k21.tar.gz

tar xvzf gempak_y2k21.tar.gz
make
make install

This morning I learned that the procedure should be:

<as 'gempak'>
cd ~gempak/NAWIPS
wget ftp.unidata.ucar.edu:pub/gempak/Y2K21/gempak_y2k21.tar.gz

tar xvzf gempak_y2k21.tar.gz
make distclean
make
make install

<as 'ldm'>
ldmadmin restart

The differences are running 'make distclean' before running 'make' and then
'make install' and then restarting the LDM to make sure that any running
GEMPAK decoders exited before new ones are run on the LDM restart.

re:

Very good.  New, source code installations that have the fixed source
code installed before doing a 'make' should result in fully functional
decoders.

NB:

I updated the gempak_y2k21.tar.gz file to contain a fix for NEXRAD Level2
use just yesterday afternoon (the code changes came from Steve Chiswell).
The new compressed tarball is now out in the pub/gempak/Y2K21 directory on
our anonymous FTP machine.

re:
> Thank you for your help as always.

No worries.  Please let us know if you run into any problems after updating
your GEMPAK installations.

Cheers,

Tom
