> The EPSG codes, WKT and the [grid mapping attributes](https://cfconventions.org/Data/cf-conventions/cf-conventions-1.9/cf-conventions.html#appendix-grid-mappings) are all redundant way to express the same information? From WKT could you deduce for example the other? Are some...

Hmm yes the NetCDF_jll is unfortunately not available for PowerPC. This is the list of platforms: https://github.com/JuliaPackaging/Yggdrasil/blob/684308e81b9249a35e6fff353f286eee12bd6a29/N/NetCDF/build_tarballs.jl#L45-L58 So we rely on which builds are available for HDF5, which is limited...

Yes, I just checked, HDF5.jl, doesn't have an issue with that HDF5_jll, so it seems both libs work individually, but not together, on Windows.

Thanks! Just curious, why did you go this route versus yanking the build from the registry? Though I suppose this way Apple M1 users still have a way to use...

> For Julia 1.8 all jll packages (with a shared dependency with julia) need to be rebuild. I've been on 1.8 beta for a while and never encountered any issues...

Ha, fascinating indeed. The opendap URL also just works, including when I load some actual data into memory (`ds["time"][:]`).

Oh that's a bummer! So do I understand correctly that it's not the HDF5 patch version 1 or 2 that is important, but whether or not netcdf is cross compiled?...

Thanks a lot for a major effort! Hope it gets easier. Looks like this issue can be unpinned as well :)

Hmm I don't really understand this anymore, perhaps something went wrong trying to keep this up to date. I don't know if others see the same on this brach, but...
