Malcom, the general problem is that those are the Linux/Unix build
instructions. They are lacking key information for Windows builds, whether
MinGW or other. I was not able to find specific Windows info for
netcdf-fortran in the on-line docs. There were a few indirect references
in the FAQ for general advice about Windows and MinGW builds.
I am not knowledgeable about windows builds, but right off this looks wrong
in your configure line, because of colons used for two different and mixed
delimiter purposes.
LD_LIBRARY_PATH=E:/Users/Malcolm/netCDF-4.7.4/lib:E:/Users/Malcolm/hdf5/
lib:E:/Users/Malcolm/zlib-curl/curl-7.70.0-win64/lib
I can't even say whether LD_LIBRARY_PATH is relevant within MinGW. I think
your best bets right now are some of those Windows references in the FAQ,
or wait for someone more knowledgeable on MinGW.
