[netCDF #FTZ-975139]: Help NetCDF compilation or installation

Not a problem; I will try to help as best I can.

I am surprised that the netcdf-c and netcdf-fortran libraries installed from 
the cygwin package manager did not work.  We should be able to work around it 
however.

I assume you are installing netcdf-c without either hdf5 or dap; assuming this 
is true, you would use the following options. Note that I am using a directory 
specific to my environment; you will need to change the paths appropriately for 
yours.

$ ./configure --disable-netcdf-4 --disable-dap --prefix=/home/WardF/local
$ make
$ make install

For netcdf-fortran, you would then compile and install it as follows:

$ CFLAGS="-I/home/WardF/local/include" LDFLAGS="-L/home/WardF/local/lib" 
./configure --prefix=/home/WardF/local
$ make
$ make install

I've set up a test cygwin system and, at this point, have downloaded and have 
tried to build GOTM, with no luck.  I know that my libnetcdf and libnetcdff (C 
and fortran libraries, respectively) built properly because they each passed 
'make check'.

If you attempt to repeat the steps as I've outlined above, does everything work 
and install properly for you?

Can you provide information re: how you are trying to build GOTM, after 
installing netcdf C and Fortran? I can try to replicate that on my system to 
further diagnose this.

Thanks, have a good day,
