Good morning Michael, > Dear Madam or Sir, > > I was making NETCDF on cygwin, and the make check install gave one error, > which I have included as requested in the output from the make command: > It appears that HDF5 was built without zlib support; NetCDF-4 support requires HDF5 be compiled with zlib support. The trick will be to rebuild hdf5 and include this support. Alternatively, cygwin offers pre-built hdf5 and netcdf packages, available for install via the Cygwin 'setup.exe' package manager. We don't maintain these packages, but a quick glance shows me that they are up to date. I hope this helps, -Ward > *** Checking HDF5 variable functions. > *** Checking HDF5 boolean variables...ok. > *** Checking HDF5 variable with unlimited dimension...ok. > HDF5-DIAG: Error detected in HDF5 (1.8.10-patch1) thread 0: > #000: H5Z.c line 1376 in H5Zget_filter_info(): Filter not defined > major: Invalid arguments to routine > minor: Bad value > #001: H5Z.c line 1019 in H5Z_find(): required filter is not registered > major: Data filters > minor: Object not found > *** Checking HDF5 deflate filter setting and getting...Sorry!
