[MITgcm-support] netcdf v3.x

[Gus Correa]

Hi Pu

Dimitris pointed out that you can use raw binary output
(from the MITgcm mdsio package), instead of NetCDF, if you wish.

However, assuming you want NetCDF output, here is a wild guess:

In your optfile, try to insert '-lnetcdff -lnetcdf' in your LIBS 
variable, say, something like this:

LIBS="-L${NETCDF_HOME}/lib -lnetcdff -lnetcdf"

(note the double 'ff" in the first), and run genmake2 again.

NetCDF-3 had only '-lnetcdf' library (for both C and Fortran),
whereas in NetCDF-4 there is one library for Fortran, one for C,
and a hierarchical dependency.

Likewise, for Lapack you may need to point to the location of your 
lapack, say:

LIBS="-L${NETCDF_HOME}/lib -lnetcdff -lnetcdf -L/your/lapack/lib -llapack"

If you are using a Lapack from Intel or ACML
it may get a tad more involved, because it may require additional (Intel 
or ACML) libraries.

I hope this helps,
Gus Correa
