Hello,
I'm building netcdf-fortran-4.5.2 on Windows 10, using MinGW. I've
installed netCDF-4.7.4 as a binary and am using these instructions to build
netcdf-fortran:
https://www.unidata.ucar.edu/software/netcdf/docs/building_netcdf_fortran.html#building_fortran_with_static_libraries
This is what I ran in an attempt to build it:
CPPFLAGS="-IE:/Users/Malcolm/netCDF-4.7.4/include
-IE:/Users/Malcolm/hdf5/include
-IE:/Users/Malcolm/zlib-curl/curl-7.70.0-win64/include"
LDFLAGS="-LE:/Users/Malcolm/netCDF-4.7.4/lib -LE:/Users/Malcolm/hdf5/lib
-LE:/Users/Malcolm/zlib-curl/curl-7.70.0-win64/lib"
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
LIBS="-lnetcdf -lhdf5_hl -lhdf5 -lz -lcurl" ./configure
--prefix=E:/Users/Malcolm/netcdf-4.7.4/lib --disable-shared
It did a bunch of checks, and at the end was:
checking for library containing nc_open... no
configure: error: Could not link to netcdf C library. Please set LDFLAGS.
I'm not sure what I should do, because I set LDFLAGS in the command. Here
is the full error from config.log:

This is my first time compiling something, and I've mostly been learning as
I go. There's a good chance I'm missing something basic here.
