[LDM #GJO-292105]: LDM Couldn't Exec Decoders Error

Chris,

> I'm having trouble with decoding LDM data for use with Gempak. The ldmd.log 
> show that almost all of the LDM data errors out with:
> Couldn't exec(decoders/<dc name>): No such file or directory. All of the 
> decoders in question are located in the NAWIPS/os/linux64/bin.
> As the LDM user I can access and execute the decoders in the Gempak directory.
> 
> LDM data is stored in the LDM's home/var/data directory. Once the LDM is 
> started the gempak directory is created with sub folders, images, nexrad, and 
> nwx. All of these contain current LDM data. Everything else needing a decoder 
> is not created.

The pqact process can't find the decoders because the directory that contains 
them (NAWIPS/os/linux64/bin) isn't in the PATH environment variable.
