The pre-built netcdf binaries *should* work with those packages, so it would be fine to refer people to those sites I think. However, the installer does come bundled with the dependencies (libhdf5.dll, libcurl.dll, zlib.dll, etc) that netcdf was built against. The issue people run in to is that these libraries live inside a directory and need to be either manually copied into a folder on the system PATH or have the folder added to the path. When building out the packaging system, I was loathe to do either of these automatically because I didn’t want to overwrite any pre-existing libraries, or modify the system path. This is becoming a larger issue, however, so I should probably revisit these decisions. Now that I’ve thought about it a moment, it seems to be that originally I ran into incompatibilities between the zlib.dll which libhdf5 links against and the zlib.dll which libcurl was linked against. Rather than digging in to it too deeply, I built and linked both against the same zlib, eliminating the issue. This was maybe 18-24 months ago, however; I don’t know if it would still be an issue. Since, as you mention, this was not apparent from the webpage where you could download the pre-built software, I will see about making this more clear; I think there is a line or two that should be made more prominent to anybody installing the binaries what *exactly* needs to happen to get the utilities to work. -Ward On Thu, Nov 13, 2014 at 1:30 PM, Don Hooper (NOAA Affiliate) < don.k.hooper@xxxxxxxx> wrote: All, > > A number of users have been perplexed by the change of format for many > of the files in our (ESRL/PSD's) archives from NetCDF3 to NetCDF4-Classic . > Many of them are Windows users, so I found the Unidata web page where they > could download pre-built software.
