William, As far as I know, HDF5 has no name conflicts with either netCDF-3 or HDF4. The only name conflicts I know about are in the HDF4 mfhdf library, which provides a netCDF-like interface over HDF4. You should not need that if you will be using netCDF-3.6.2. You may find that the simplest way to avoid conflicts is just to leave off the "-lmfhdf" linker flag when you build your application, which should prevent the mhhdf library from being searched. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: TOQ-874116 Department: Support netCDF Priority: Normal Status: Closed
