[netCDF #UTY-793114]: Problems with netcdf and ECHAM5 on AIX5.3

Hi Terry,

Sorry it has taken so long to respond to your question ...

Are you using the same Fortran compiler that was used when building the 
netCDF-3.6.2
library you have installed on your machine?  Different Fortran compilers have
different ways of calling C functions in the netCDF library, and this could be
the source of the problem.  Note that the GNU C compiler does not mix well with
the AIX Fortran compiler.

It's also possible that your netCDF library was built with a separate netCDF 
Fortran 
library, in which case you would need to specify

  -lnetcdff -lnetcdf

instead of just 

  -lnetcdf

at the end of the compile line.

Alternatively, you could download the latest netcdf-4.1.1 release from

  ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.gz

and build that.  If you specify --disable-netcdf-4 to the configure script,
it only builds the netCDF-3 interfaces.  That way you could specify the 
same Fortran compiler you are using and make sure it is compatible with the
C compiler used to build the libraries.  You would also get the new "nc-config"
program, which makes it easier to know how applications should be built with
the library.  For example, invoking "nc-config --flibs" shows the library flags
that should be used with the installation after it's built.

Please let us know if this doesn't help ...
