[netCDF #HFH-711245]: Linking from Windows Fortran to NetCDF 4.2 shared library

Good afternoon Graham,

I'll try my best to help you out.  A couple of things to start; first, 
beginning with 
netCDF 4.2, the netCDF-C and netCDF-Fortran libraries have been separated 
from each other.  The netCDF-Fortran source code is available for download
from:

http://www.unidata.ucar.edu/downloads/netcdf/netcdf-fortran/index.jsp

The netCDF-Fortran libraries depend on the netCDF-C libraries, so those will
need to be installed first.  

The pre-built libraries you reference, netCDF-4.2.dev-NC4-64-shared, built
using a developer snapshot; these are netCDF-C libraries.  The are built
specifically for use with Visual Studio and/or in a development environment
using the Microsoft development libraries.  Work to provide corresponding
netCDF-Fortran libraries is ongoing, but they are not yet available.

The netCDF-C and corresponding netCDF-Fortran libraries can be used on
Windows when using the MSYS/MinGW or Cygwin
development environments.

You mention the difficulties you've had building the 64-bit MinGW C compiler;
it is certainly true that it is not very intuitive.  According to my notes, I 
was able
to build MinGW-64 using the code available at: 

http://sourceforge.net/projects/mingw-w64/.

Once downloaded, I have a note to follow the directions in 'mingw-w64-v2.0.7/
mingw-w64-doc/howto-build'.  Note that I built MinGW-64 inside of the MSYS 
environment, installed from here: http://www.mingw.org/wiki/MSYS

If you were to go this route, I can confirm that the netCDF-C and netCDF-Fortran
libraries appear to compile with MinGW.   Likewise, if you were able to use
cygwin, the netCDF-C and netCDF-Fortran libraries are available as packages
which can be installed from the cygwin package manager.

I'm sorry I can't point you to an MFC/Windows-developer-library compatible 
netCDF-fortran library, but hopefully this information will help.

Have a great evening,

-Ward

p.s., I notice that this support request is entered in our system twice; I will 
close the earlier one, but leave this one open if there are any questions I
can help with.
