Is this about the two issues discussed here, or are there more problems? I am asking because I am wondering whether to back-port the patches to 4.9.1?

In the conda-forge build, we did not install the necessary hdf5 plugins. I fixed that in conda-forge/libnetcdf-feedstock#172. There we also added blosc as a dependency, which was not present before. The netcdf-c quirk is that, if a compression library is not present at build time, support for it will not be compiled and the call to setting the corresponding compression will silently *succeed*, but not do anything. If the library is present at build time, but the corresponding plugin is missing at runtime, the attempt to set compression will error out. With the most recent libnetcdf-4.9.2 builds one should get working plugins, including working blosc compression. Regarding the HDF5-diag errors, the upstream bug has already been mentioned. I am suggesting to back-port it in conda-forge/libnetcdf-feedstock#175 for the conda-forge build, so hopefully that will work in libnetcdf-4.9.2 soon, too.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1503046820
