Hi,

Sorry, but I can't duplicate the problem on our HP-UX B.11.00 E
9000/785 system with our older compilers.  Since the ncdump problem
has nothing to do with the Fortran or C++ interfaces for netCDF, I
didn't build those, but just used:

 CC=/opt/ansic/bin/c89
 CPPFLAGS='-D_HPUX_SOURCE -D_FILE_OFFSET_BITS=64'
 CFLAGS=+DD64
 FC=''
 FFLAGS=-w
 F90=''
 CXX=''

and everything worked fine, including "make all" and "make test".  In
particular, building ncdump worked OK:

 Making `all' in directory /home/russ/netcdf/build/tweety-64o/src/ncdump

         /opt/ansic/bin/c89 -c +DD64 -I../libsrc  -D_HPUX_SOURCE 
-D_FILE_OFFSET_BITS=64 ncdump.c
         /opt/ansic/bin/c89 -c +DD64 -I../libsrc  -D_HPUX_SOURCE 
-D_FILE_OFFSET_BITS=64 vardata.c
         /opt/ansic/bin/c89 -c +DD64 -I../libsrc  -D_HPUX_SOURCE 
-D_FILE_OFFSET_BITS=64 dumplib.c
         /opt/ansic/bin/c89 -o ncdump +DD64  ncdump.o vardata.o dumplib.o 
../libsrc/libnetcdf.a  

So if the problem is specific to a newer version of HP-UX or newer
versions of the compilers, I'm not sure how to diagnose it, since I
can't duplicate the problem.  I'm investigating if we can get access
to a more up-to-date HP-UX platform, but if not, you may have to join
and ask about the problem on the address@hidden mailing
list.

Alternatively, since the error message you got said 

 Unknown input file type: "../libsrc/libnetcdf.a"

for what should have been a sinple static library, you could check to
make sure the file libsrc/libnetcdf.a didn't get corrupted or
truncated by something else while you were building ...
