	Two versions of HDF seem to be common: HDF4 and HDF5. I'm not clear yet which MODIS uses when they call theirs "HDF-EOS". But anyway. There are some ready-built binary libraries for both [https://support.hdfgroup.org/release4/obtain.html HDF4] and [https://support.hdfgroup.org/HDF5/release/obtain518.html HDF5] which look promising. Some linux builds, and also Windows builds in release mode, both 32-bit and 64-bit, built with Visual Studio 2013 and 2015. That's more helpful than most.

Some linux builds, and also Windows builds in release mode, both 32-bit and 64-bit, built with Visual Studio 2013 and 2015. That's more helpful than most. So.... Here are windows instructions. If you do this for linux, tell me how and I'll add instructions.

	~~Working out how~~ to ~~use them~~....		* Download the Library above, 64-bit, and the Visual Studio you're using, extract it, and run the installer, which unzips the library to a place of your choice. I recommend a place without spaces in the directory names - it usually makes things simpler somewhere along the lines. For this example, suppose you install it in C:\Lib\HDF.
			* Get your project open in Visual Studio, and get into Release x64 bit mode. Open a C file, so you get the right project preferences, and then...
			* Open Project Preferences - check it's still configuring 64-bit Release mode.
			* In C/C++, General, Additional Include Directories, insert '''C:\Lib\HDF\include;''' (for example)
			* In Linker, Input, Additional Dependencies, insert '''libxdr.lib;libszip.lib;libjpeg.lib;libzlib.lib;libmfhdf.lib;libhdf.lib;''' - which is a bit eye-boggling.
			* In Linker, General, Additional Library Directories, insert (for example) '''C:\Lib\HDF\lib;'''
