Hi Gilbert, re: 32-bit GEMPAK decoders on a 64-bit OS > What I mean is this: I compiled GEMPAK on vm-weather3. Shouldn't the > program compiled as 64-bit by default? Yes. re: > And if so, where are the decoders? The GEMPAK decoders built on vm-weather3 are located in: /home/gempak/NAWIPS/os/linux64/bin These are _not_ copies of the decoders located in /home/gempak/decoders, AND the decoders in /home/gempak/decoders are the ones that are trying to be used from the GEMPAK pattern-action file being used by the LDM on vm-weather3: <user 'ldm' logged into vm-weather3> cd /home/ldm% which dcgrib2 /home/ldm/decoders/dcgrib2 /home/ldm% file /home/ldm/decoders/dcgrib2 decoders/dcgrib2: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped /home/ldm% file /home/gempak/NAWIPS/os/linux64/bin/dcgrib2 /home/gempak/NAWIPS/os/linux64/bin/dcgrib2: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, not stripped It looks to me like the GEMPAK decode executables in /home/ldm/decoders are copies from some other machine when they should be copies of those built on vm-weather3. Here is what I would do now: <as 'ldm' on vm-weather3> cd ~/decoders cp /home/gempak/NAWIPS/os/linux64/bin/dc* . This should take care of all of the GEMPAK decoders. The next step would be to replace the non-GEMPAK decoders in /home/ldm/decoders with 64-bit versions built on vm-weather3.
