The binaries we make available were compiled with the Microsoft
Digital C++ 6 compiler, and unfortunately are only compatible with the
Microsoft Digital Fortran 6 compiler.  This is because each compiler
uses different conventions for calling C functions from Fortran, and
the netCDF Fortran interface is implemented using a thin veneer of
Fortran routines that call the underlying C library.

However, you might be able to adapt the steps documented by Dirk
Slawinski for linking netCDF with Fortran programs compiled by the
Lahey Fortran compiler on Win32 systems:

Also, I'm not sure if this is applicable, but Tom Grills has

  ... recently developed an ActiveX Library that allows manipulation
  of netCDF files in any win32 development environment which supports
  Active X, including Visual Basic.  I have a trial version available
  to anyone who is interested in trying it out.  It requires the win32
  build of the netCDF.dll but once registered, can easily be
  referenced from within VB, Excel, Access, Dephi, C++, etc....

  If you would like to try the trial version, contact me directly...

Several people have managed to build the netCDF library from source
with Absoft compilers on other platforms (Mac OS X, Linux):

  http://www.unidata.ucar.edu/packages/netcdf/other-builds.html#absoft-macosx

I'm not aware if anyone has succeeded in doing this on a Win32
platform.  There's a little more information in replies to support
questions about building the Fortran interface with Absoft compilers
you can get by entering "absoft" as the search keyword in a search of
the netCDF support email archive at the bottom of the netCDF home
page:

  http://www.unidata.ucar.edu/packages/netcdf/

If you find a way to make this work, please let us know and we'll
document it for others.
