First, I notice you are not compiling with the -D_HPUX_SOURCE flag that
we recommend in our instructions for building netCDF on this platform
(in the INSTALL file at the top-level).  This means you haven't set the
environment variable CPPFLAGS="-D_HPUX_SOURCE -DNDEBUG" as we recommend
before running the "configure" script.  Please follow the instructions
in the INSTALL file for this platform (after first running "make clean"
and removing the config.cache file), and if you still have problems,
please include the information requested at the end of the INSTALL file
in reporting the problem.  This will help us diagnose the problem more
quickly.

In case this isn't the source of the problem, the cpp problem you
reported occurs for "fort-attio.c", the first source file compiled in
that directory that attempts to

 #include "ncfortran.h"

and that file includes another file containing a huge number of macro
definitions:

 #include "cfortran.h"

(The purpose of these .h files is to isolate and handle all the many
ways C functions are called from Fortran on a large variety of
platforms.)

All these macro defintions have probably exceeded the capacity of your C
preprocessor (cpp), though we don't see any problems on our HP-UX
10.20/9000 platform.  If this is the problem, all I can suggest is that
you try to use the -H cpp flag to increase the cpp capacity to
handle macro definitions.  This flag changes

   ... the internal macro definition table to be nnn bytes in size.  The
   default buffer size is at least 8188 bytes ...

so you might try setting the environment variable CPPFLAGS to something
like "-H50000" before invoking the configure script (after removing
config.cache and running "make clean").

Yes, you need the FORTRAN interface to call netCDF FORTRAN functions
from a FORTRAN program.  In building the netCDF library, the C
interfaces are compiled first, so if the build fails in compiling the
FORTRAN interface, it never gets added to the libnetcdf.a, so you would
expect that the unsatisfied externals you are seeing would result.

You can also get a copy of the 3.3.1 netCDF libraries and executables already
compiled and built for the HP-UX 9.05/9000 platform from
