Excellent!

Interesting.  I have never run into a situation where a 'make install_setuids' 
would fail
to set the setuid root bit on the 'hupsyslog' and 'rpc.ldmd' executables 
_except_ on
systems where the LDM installation was on an NFS-mounted file system.  The 
reason for
those failures were that NFS-mounts can be set to not allow setuid root 
invocations.

They look correct now.

I would bet that you are seeing more errors because more decoding actions are 
now being
run.

The errors you are seeing are not due to a new version of the LDM.  Rather, 
they are
due to the LDM attempting to run more decoding actions.

> Were they possibly not able to write the log files?

Probably not.  The GEMPAK decoder actions in the various pattern-action files 
will
write log output to ~ldm/data/gempak/logs.  Presumably your ~ldm/data directory
is writable by the user running your LDM.  If yes, then the actions run by pqact
should be able to create directories as needed (e.g., ~ldm/data/gempak, etc.).

I will look through the ldmd.log file you sent previously to see if anything 
strikes
me.

Question:

- I assume that you copied the GEMPAK decoders to a directory in the PATH of the
  user running your LDM (recommended directory is ~ldm/decoders) (?).

  Did you verify that those decoders are runable on your machine?  For instance,
  what is the output of the following:

  <as 'ldm'>
  cd ~ldm/decoders         <- wherever you copied the GEMPAK decoders to
  ldd dc*

> Anyway, thanks for all the help today.  Sorry, I took so much of your time.

No worries.

Cheers,

Tom
