First, it is a bit unusual to write data to a directory under /var, but
let's not worry about that at the moment.
Second, The listing you sent in a previous email showed that there was a
'data' directory under ~ldm, and it did not appear to be a link to another
directory. Is ~ldm/data now gone?
> [wxmanldm@godelsrevenge bin]$ ln -s ldm-6.6.3 runtime
What directory were you in when you make this link? It looks like you were in
the ~ldm/bin directory. If this is true, then you were in the wrong place
to make the runtime link.

Yup, this shows that you are in a 'bin' directory somewhere. This is not where
the
runtime link should be. Given this, please remove the runtime link you just
made.
Next, do the following:
<login as 'ldm'>
cd ~ldm <- go to the HOME directory of user 'ldm'
rm runtime <- remove the runtime link that is there (if it
is there)
rm -rf bin include lib man src <- your original directory listing showed that
you
had these directories under ~ldm, not in a
runtime link
ln -s ldm-6.6.3 runtime <- the runtime link has to be in the HOME
directory
ln -s runtime/* . <- this assumes that the bin, include, lib,
man, and src directories exist under
~ldm/ldm-6.6.3
mkdir decoders util <- useful directories to have; this is pretty
standard
-- edit your shell configuration file (e.g., .cshrc for C shell, .bash_profile
for Bash, etc.) and make sure that the ~ldm/bin, ~ldm/decoders, and ~ldm/util
directories are included in the PATH definition
> [wxmanldm@godelsrevenge bin]$ df -k data
> df: `data': No such file or directory
Please do the following _after_ performing the steps above:
<still as 'ldm'>
cd ~ldm
df -k
Send us the results.

> [wxmanldm@godelsrevenge bin]$ cd ~/
> [wxmanldm@godelsrevenge ~]$ ls

This reiterates that you were in the wrong place when you made the runtime link
you reported at the beginning of this email.
> [wxmanldm@godelsrevenge ~]$ cd ~/bin
The 'bin' directory containing LDM executables should be accessible through a
runtime link in the HOME directory of 'ldm'.
I believe that once you have the runtime link structure setup correctly, you
will be good to go _unless_ the ~ldm/data directory is incorrect, and _unless_
you need to rebuild the LDM distribution.
Question:
It appears that when the operating system was upgraded from FC5 to FC6, you
removed the home directory for 'ldm' and then restored a backup that was made
before all of the exchange we had about how to setup ingestion and decoding
of MADIS data. Is this the situation?
Cheers,
Tom
