I was able to successfully build and test the netCDF 3.5.0 package on
the following system:

    $ uname -a
    HP-UX tweety B.11.00 E 9000/785 2004553471 8-user license

using the following set of environment variable settings:

    CC=/bin/cc
    CPPFLAGS='-D_HPUX_SOURCE -D_FILE_OFFSET_BITS=64'
    CFLAGS='-g +DD64'
    FC=/opt/fortran90/bin/f90
    FFLAGS='-w +noppu +DA2.0W'
    FLIBS=-lU77
    CXX=''

Notes:

    1.  The C++ compiler (/bin/CC) can't build a 64-bit mode object file.

    2.  The Fortran-77 compiler (/opt/fortran/bin/fort77) can't build a 
        64-bit mode object file.

    3.  The "+noppu" option to the Fortran-90 compiler means that it
        won't postpend an underscore (_) suffix to global symbol names.


If you want to try this on your system, then

    1.  Go to the top-level source directory.

    2.  Perform steps 3 through 5 described near the end of the file
        INSTALL.html.

    3.  Set the environment variables according to the above.  You may
        add non-conflicting options (such as for optimization).

    2.  Perform steps 6 through 9 described near the end of the file
        INSTALL.html.
