Dorothy, The IRIX configuration of GEMPAK 5.8.3a is to build (using C99) the default library configuration (n32 or o32) of your system. Also, the GEMPAK distribution builds its own libnetcdf.a which will be compatible with itself and installs in $NAWIPS/netcdf/irix/lib. At that point, you only have to build a udunits library again using the default library format of your system. I do provide dcreanal2 in the GEMPAK distribution for converting reanalysis data as well, but you probably have particular configurations of your own program to maintain. Steve Chiswell Unidata User SupportFrom: Dorothy Durnford <address@hidden> Organization: UCAR/Unidata Keywords: 200508161502.j7GF2fjo026603Hi Steve, I've inherited a program that converts netcdf files, e.g. the NCEP reanalysis files, into gempak files. It used to work beautifully. Unfortunately, the netcdf libraries were removed. Our computer expert downloaded the netcdf and udunits libraries from your netcdf site and installed them. When I compile the conversion program without forcing the type of object produced or with forcing o32 objects to be produced, I get the fatal error "Expecting o32 objects: /usr/local/netcdf/lib/libnetcdf.a (v2i.o) is n32. When I force n32 objects, I get the fatal error "Expecting n32 objects: /usr/local/udunits/lib/libudunits.a (utlib.o) is o32. Gempak needs o32>from past experience, so, our expert downloaded the o32 version of thenetcdf library. I still get the message saying that it is n32. Do you have any suggestions? Thanks, Dorothy.-- **************************************************************************** < Unidata User Support UCAR Unidata Program < (303)497-8643 P.O.
