Gilbert,

re: directories, etc. for 'mcidas' under Fedora

One mistake in my last line.  It should be:

make install.all VENDOR=-g77

>OK. Did that on weather2. Now, the ADDE stuff doesn't work.

Which ADDE stuff?  The pointing to datasets and definition of datasets
does not get touched with either a 'make clobber' or 'make install...'.

I just logged onto weather2 (via weather3) and see the problem:
/usr/bin/compress and /usr/bin/uncompress are not there.  The specifying
of MCCOMPRESS=TRUE in your environment forces you to have compress/uncompress
installed in order for the "compress" compressed ADDE transfers to
work.

compress is contained in ncompress-4.2.4-34 rpm.  Here is how I found
this out on our machine that had a _full_ Fedora install:

% rpm -q -f /usr/bin/compress 
ncompress-4.2.4-34

So, you need to grab that RPM and install compress/uncompress (actually,
uncompress is just a link to compress after the installation).

>(just fixed it---still didn't help anything).

re: exporting X displays back to the UPC
>Arrgh!

I found out that the problem is that you are setting the DISPLAY
environment variable.  To tunnel X, DISPLAY has to be set by ssh.

re: changes needed in CFDGONLY.BAT

OK, sounds good.

re: cron job that runs CFDGONLY.BAT
>Yes, I run it out of McIDAS.

So, why are the files owned by 'ldm'.  With that ownership, and with
the write permissions set to only allow owener to write to the
GIF files, the BATCH file will hang waiting for you to answer if
it is OK to overwrite.

OK.

The broken pipes for the profiler decoder would be caused by write problems
for the decoder or by there not being the SCHEMA, ROUTE.SYS, and SYSKEY.TAB
files in the directory into which the decoder is trying to write output.
This would parallel the permissions I am seeing on the GIF files for
the web pages.
