[netCDF #CXR-134834]: linking netCDF library with program written in Fortran

Hi Ana,

Sorry to have taken so long to respond to your question ...

NetCDF doesn't install any library named "libnc.a", only libnetcdff.a (for 
libnetcdf.a (for C), and libnetcdf_c++.a, for C++.  You generally don't need the
C++ library, unless JULES requires it for some reason.  The Fortran netCDF 
calls the C library, so you generally need to link Fortran applications with 
as your output from nc-config --flibs shows.  The Makefile also must know where 
netcdf.h, netcdf.inc, and netcdf.MOD files are, usually all in the same

The format of .mod module files is compiler-specific, so if you used a 
different Fortran
compiler than gfortran (or even an earlier version) when you built the netCDF 
library from source, it might generate such an error.  Also if you just copied 
the .MOD
file into the /Users/Nana/netcdf/include directory from a different directory 
where it was
built for a different platform or compiler, you would see such an error.

Otherwise, I don't know what would cause this.

I suspect you would might better advice asking the JULES help-desk or 
support about this problem, since it may be related to something in
the JULES Makefile.
