[LDM #FPM-496740]: gempak decoders failing



Hi Dave,

So, I've been on twister for quite awhile this afternoon, and I am sorry to
say that I have not been able to figure out what the problem with running
PIPE actions is :-(

I do have some observations that I want to get down "on paper" before I
forget them:

- I rebuilt LDM-6.13.4 from source just to make sure that there were no
  weird things during the build

  This didn't help.

- I dropped back to using the old LDM installation, LDM-6.12.6, and this
  also did not result in PIPE actions working (!?)

- I noted that the PATH in scope for 'ldm' had GEMPAK directories before
  system ones, and this resulted in the GEMPAK 'ps' command being used
  instead of the system /bin/ps when doing things like 'ps -u ldm'

  I changed the order of the 'path' definition in your ~ldm/.login file.

- I noted that you are defining LD_LIBRARY_PATH in ~ldm/.login and that
  you put the /usr/local/miniconda/lib first

  Since I think that this is a bad idea, I redefined LD_LIBRARY_PATH
  in ~ldm/.login and put /usr/local/miniconda/lib last.  I also removed
  the non-existent /usr/lib/64 part of the definition.

- I tried changing a number of things in the 'dcmetr' action in
  ~ldm/etc/pqact.gempak, but nothing I tried got things working

- by poking around, I found that the CONDUIT STUDIOFILE action in
  ~ldm/etc/pqact.conf is (or, at least, seems to be) working
  correctly

- I noted that GEMPAK decoding seems to have stopped back in mid-June

  Does this jibe with your view of things?

I wrote up a note to bring Steve Emmerson up to date on what I found
on twister and asked him to login to take a look.

Sorry that I couldn't figure this one out!  Hopefully, Steve will be
able to figure out what is going on!!
 
Cheers,

Tom
