Hi Tim, We don't have access to a Cray XT platform, but if you send us the items listed here: http://www.unidata.ucar.edu/software/netcdf/docs/netcdf-install/Reporting-Problems.html we may be able to figure this out. It would also be helpful to see the file fortran/nfconfig.inc, which is supposed to be where the NF_INT_IS_C_INT or NF_INT_IS_C_LONG macro gets defined. Thanks! --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: IMT-385711 Department: Support netCDF Priority: Normal Status: Closed
