Mike,

>New question. In order to allow the two pc's to get the data feed from
>cyclone, is it the /ldm/data directory that needs to be shared via NFS?

Yes, but remember that the actual filesystem is /data/ldm.  ~ldm/data
is a link to /data/ldm.

>Also, since the data will reside on cyclone, is there a need for the
>mcadde account? 

There is a need for the 'mcadde' account on cyclone, but not necessarily
any of the machines that will act as clients.  The only reason that you
might want to setup the ADDE remote server on all of the machines is
so that people can make datasets (e.g. case study data collections) that
are local to one machine accessible to others using ADDE.  You might,
on the other hand, decide to keep all sharable datasets on the primary
server, cyclone.

I logged onto cumulus and took a quick look.  The problem above is that
the link for nidsadir, nidsaget, nowradir, and nowraget were failing.
This can be seen from the make log file, ~mcidas/mcidas7.6/src/makelog:

./mccomp -O -vendor -I. -I../netcdf/libsrc -c nidsadir.c
gcc -c -O -ansi -D_GNU_SOURCE -I/usr/X11R6/include -O -I. -I../netcdf/libsrc 
nidsadir.c
nidsadir.c: In function `main':
nidsadir.c:146: warning: passing arg 1 of `GetConfigInfo' discards `const' from

compile nidsadir.c:             done
./mccomp -O -s -vendor -o nidsadir nidsadir.o -L. -lmcidas

This seems to indicate that the correct version of sevutil.c was not included
in the update that I put out in the unix/760/bugfix directory.  This had
me in a panic to say the least.  When I looked at the servutil.c source
on your system, however, I saw that it was the correct code.  Apparently
the time stamp on servutil.o had kept it from being remade by the make
process (weird).

I got around this by:

<login as 'mcidas'>
cd mcidas7.6/src
rm servutil.o
make servutil.o
make nidsadir nidsaget nowradir nowraget
ls -l nidsadir nidsaget nowradir nowraget
-rwxrwxr-x   1 mcidas   ldm        469844 Sep 22 19:04 nidsadir
-rwxrwxr-x   1 mcidas   ldm        472996 Sep 22 19:04 nidsaget
-rwxrwxr-x   1 mcidas   ldm        460208 Sep 22 19:04 nowradir
-rwxrwxr-x   1 mcidas   ldm        463520 Sep 22 19:04 nowraget

You can see that they now exist, so you should be able to do the
make install.mcxall step with no hangups (at least not from these
routines not being made).
