I’ve recently built a simple reading app for NetCDF using the nf90 flags and it
only worked once I used these flags to gfortran:
-I/usr/include -lnetcdff
I’ve installed NetCDF to my /usr/lib instead of /usr/local by purpose... Or did
gentoo did it for me, I don’t quite remember.
But pointing the mod file search to that path and using netcdf[F] instead of
plain netcdf did the trick for me.
Again, it was not for JULES compilation, but you might try changing your
LIB_PRE and MOD_INC to
LIB_PRE=-lnetcdff
MOD_INC=-I<path_to_your_413_include_dir>
Notice that LIB-PRE begins with a lowercase L while MOD_INC is a uppercase i.
:) (if the font above is not on Courier New for you it would be hard to notice
the difference)
You might change LIB_INC also to -L<path_to_netcdf_lib> if you installed it
somewhere else not on /usr or /usr/local as --prefix. If you installed in your
home directory under ‘netcdf’ for example, it would be:
LIB_INC=-L${HOME}/netcdf/lib
LIB_PRE=-lnetcdff
MOD_INC=-I${HOME}/netcdf/include
Remember I had to specify -I in order to find the correct .mod file despite it
being installed under /usr/include. I was only relieved of the -L argument.
I hope that helps.

Subject: Re: [netcdfgroup] JULES v3.3 make BUILD results in errors on my Ubuntu
machine
I don't know about JULES, but:
The complaint refers to your netcdf 4.1.3 version not being compiled with
NetCDF 4 support (you have to enable this via a configure flag).
Second, I can't remember if NetCDF 4 automatically defines nf90_mpiio even if a
non-mpi compilation has been performed, if so that should also disappear.
Otherwise you need to compile netcdf with MPI enabled (you can ask your
colleague whether (s)he used MPI or not.
The flag for the configure script for enabling Netcdf 4 support is:
--enable-netcdf-4
If you compile with MPI it will automatically be detected.
I sure do hope you are not using gcc v.1.2.1
I do hope that is a typo! :)
If not, please use a more recent version of gcc/gfortran.
Lastly, the newer NetCDF should be preferred. Possibly you have had errors
which refers to the DAP support, if so, configure with the "--disable-dap" flag
to disable DAP support.
Kind regards Nick

Dear,
I compiled and installed NetCDF 4.1.3 succesfully on my Ubuntu machine (newer
versions of NetCDF gave some errors). Then I tried to install the land surface
model JULES 3.3. This failed at running:
make BUILD=run COMPILER=gfortran
I got the following errors:
Error: Symbol 'nf90_netcdf4' referenced at (1) not found in module 'netcdf'
Error: Symbol 'nf90_mpiio' referenced at (1) not found in module 'netcdf'
I tried changing variables in the Makefile.comp.gfortran. With the settings
shown here beneath, a colleague was able to successfully install JULES on a
Mac, by I failed on my Ubuntu (3.5.0-32-generic #53~precise1-Ubuntu). I have
got no idea anymore what to do.
Thanks very much for any help!
