Ok. First you should decide if you actually need all those capabilities. For each one, you will need to install the corresponding library. netcdf-4 requires libhdf5 and libhdf5-hl (https://support.hdfgroup.org/HDF5/) - please use version 1.8.18. Do not use 1.10. hdf4 requires libhdf4 (https://support.hdfgroup.org/products/hdf4/) pnetcdf requires libpnetcdf (https://trac.mcs.anl.gov/projects/parallel-netcdf/wiki/Download) =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: BGF-782150 Department: Support netCDF Priority: Emergency Status: Closed =================== NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
