Unfortunately, MS has done such a nice job of crating incompatible run-time libs, and tying the compiler version to the lib version, that libraries built with one version of the compiler can only be counted on to work correctly with executable built with the same version. So it would be helpful to provide multiple Windows binaries (yeah!). For instance, the Python provide by python.org is built with VS2008, so libraries used by extensions ideally should also be built with VS2008, and the libs Unidata is currently providing appear to be built with VS 2010. Yes, a total nightmare, this. Honestly, I'm not sure where the incompatibilities lie, so these _may_ work OK, but I'm not sure they can be relied on.

But if you are building binaries of your code to re-distribute, it' snot so easy... Also, folks using higher level languages that need netcdf, like Python, R, what have you, are generally not set up with a full *nix system like homebrew and macports. So pre-built binaries would be useful here. Though maybe that's the job of the wrapper maintainers, or language community. But it is really a pain to build these packages so that they can be re-distributed, I've been meaning to do it for Python for years, and haven't gotten around to it yet ;) (for python, there is now Anaconda and Enthought Canopy, that deal with this for folks, so maybe no need for Unidata to do it) -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker@xxxxxxxx
