The z library (usually called zlib) is a popular and widely used library for lossless compression, which is already included with many Unix systems, but can also be downloaded and installed from various package management systems (for example dpkg, yum, homebrew, macports, anaconda, ...) or built from source (see http://www.zlib.net/). NetCDF-4 depends on an HDF5 library that is built with zlib enabled, so zlib must be built and installed before HDF5, which must be built and installed before netCDF-4. The package management systems mentioned above will do this for you, but if you need to build the libraries on which GMT depends from source for some reason, see these instructions for building the netCDF-C library with zlib and hdf5: http://www.unidata.ucar.edu/software/netcdf/docs/getting_and_building_netcdf.html#build_default If you are having trouble building HDF5 with zlib, please consult the HDF5 installation instructions: https://www.hdfgroup.org/ftp/HDF5/current/src/unpacked/release_docs/INSTALL --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: OEJ-560742 Department: Support netCDF Priority: Normal Status: Closed
