We think netCDF can be used with Win64, but it requires building from
source using the right options for specifying a 64-bit environment for
the compilers you use.  Various compilers have different ways of
specifying a 64-bit environment, and you also have to make sure the
right include files and library paths are used.

We have not tested netCDF for Win64, however, so it may be that some
changes are required in the source.  There is currently only one
"#ifdef WIN32" test in the libsrc4 files, for example, so that would
probably have to be changed to "#if defined(WIN32) || defined(WIN64)".

Please note that it is not necessary to compile netCDF in Win64 to be
able to use the 64-bit offset format of netCDF or to use netCDF-4.
Currently all netCDF formats supported by Unidata software may be
written or read using only a 32-bit development environment.  The only
kind of netCDF file that currently requires 64-bits is the new "CDF-5"
format recently announced for the parallel netCDF package developed
separately by Argonne Labs and Northwestern University:
