Hi Leiph, I believe that is the known 3.6.2 bug documented here: http://www.unidata.ucar.edu/netcdf/docs/known_problems.html#cxx_64-bit and fixed in subsequent releases. Try either version 3.6.3: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-3.6.3.tar.gz or the latest version 4.0.1-beta3, which still just builds the netCDF-3 version if you don't specify --enable-netcdf4 in the configure step: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.gz --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: MNK-974179 Department: Support netCDF Priority: Normal Status: Closed
