Those commands don't set the environment variables used by the
configure script.  I assume you are using "csh" or "tcsh" for your
shell, since you are trying to set environment variables with this
kind of command.  You need to use the "setenv" command, not the "set"
command to set environment variables.  For example:

 setenv CC=gcc
 setenv CPPFLAGS="-DNDEBUG -D_HPUX_SOURCE"
 setenv CFLAGS=-O
 setenv CXX=g++
 setenv FFLAGS="-O3 -w"
 setenv FC="f77"

I've changed the "-DhpuxFortran" to "-D_HPUX_SOURCE" in the settings
above, because that's what's recommended in the INSTALL file for HP-UX
10.20, at

  http://www.unidata.ucar.edu/packages/netcdf/INSTALL

That file also recommends using FC=/opt/fortran/bin/fort77, but I
don't know if that Fortran compiler works with calling C functions
compiled by gcc, so maybe f77 will work as you are trying.  If you
don't actually need the Fortran interface for netCDF, you can specify
FC="" to indicate you only need the C and C++ interfaces.

The fact that it found "fort77" indicates you have it installed, so if
you really need the Fortran interface and f77 doesn't work, try fort77
instead.

The fact that the flags to the Fortran compiler were "-O" rather than
the "-O3 -w" you had specified as the value of FFLAGS indicated the
FFLAGS environment variable was not set, since you used "set" instead
of "setenv".
 
If you need any more help setting environment variables, see the
