[netCDF #LQZ-375894]: Problem(s) using netcdf fortran library 4.4.2

Hello Sourish,

You are correct that the netcdf fortran and C interfaces have been separated 
out; however, the former still has a dependency upon the latter.  The C library 
(libnetcdf) is the `core` library, and the various interfaces (Fortran, C++, 
Python, etc) require the core C library.  Installing the C library should 
resolve the issue for you!

I hope this helps, please let me know if there are still issues!

Have a great day,

-Ward

> strict -g' FFLAGS='-m64 -O3 -xSSE4.2 -fPIC -ftz -fp-model strict -g' 
> FCFLAGS='-m64 -O3 -xSSE4.2 -fPIC -ftz
> -fp-model strict -g'

> Things worked as expected during the "make && make install"

> $ nf-config --flibs -L/u/sbasu1/packages/netcdf-fortran/4.4.2/lib -lnetcdff 
> -lnetcdf
> $ ls /u/sbasu1/packages/netcdf-fortran/4.4.2/lib libnetcdff.a libnetcdff.la 
> libnetcdff.so libnetcdff.so.6 libnetcdff.so.6.0.1 pkgconfig
