[LDM #FPM-496740]: gempak decoders failing

Dave,

Found the problem (I was off-base).

The GEMPAK decoders require a Python shared library:

    [ldm@twister etc]$ ldd /home/gempak/GEMPAK7/os/linux64/bin/dcgrib2
            ...
            libpython2.7.so.1.0 => /usr/local/miniconda/lib/libpython2.7.so.1.0 
(0x00007f92f1435000)
            ...

and won't work it it can't be found:

    [ldm@twister etc]$ LD_LIBRARY_PATH= ldd 
/home/gempak/GEMPAK7/os/linux64/bin/dcgrib2
            ...
            libpython2.7.so.1.0 => not found
            ...

and the pqact(1) process doesn't have LD_LIBRARY_PATH set:

    [ldm@twister etc]$ ps -p 13761 -ww e | fgrep LD_LIBRARY_PATH
    [ldm@twister etc]$ 

Probably because ldmadmin(1) is a Perl script and the perl(1) utility deletes 
that environment variable.

A solution might be to use yum(8) to install the native Python library. It 
would likely be installed in /usr/lib64 and, consequently, found by the dynamic 
loader.

Regards,
Steve Emmerson
