I regret to inform you that the netCDF package cannot be built for large
file system support on a SunOS 5.6 system.  This is because the netCDF
code uses the "off_t" type in a way that conforms with the UNIX standard
but that is incompatible with the non-conforming implementation of that
type under SunOS 5.6.

To see this for yourself, do the following

    1.  Go to the top-level source directory of the netCDF package.

    2.  Execute the command "make distclean".

    3.  Remove file "make.cache" if it exists.

    4.  Set the following environment variables to the indicated values:

          export CC=/opt/SUNWspro/bin/c89
          export CPPFLAGS=-DNDEBUG
          export CFLAGS="-O `getconf LFS_CFLAGS`"
          export FC=/opt/SUNWspro/bin/f77
          export FFLAGS="-O -w"
          export F90=
          export CXX=
          export LDFLAGS=`getconf LFS_LDFLAGS`
          export LIBS=`getconf LFS_LIBS`

        NOTE: The above assumes a standard shell.  csh-derived shells
        use a different syntax.

    5.  Execute the "configure" script.

    6.  Execute the command "make".  It will quickly fail with the
        following error:

            ...
            Making `all' in directory /tmp/netcdf-3.5.0/src/libsrc
            ...
            /opt/SUNWspro/bin/c89 -c -O -D_LARGEFILE_SOURCE 
-D_FILE_OFFSET_BITS=64 -I.  -DNDEBUG nc.c
