Howdy Roy!

Thanks for pointing this out!

I am in the process of updating the netCDF-4 on-line documentation
today. Here's part of the revised installation manual, which will
answer your above questions.

Thanks!

2 Quick Instructions for Installing NetCDF on Unix
**************************************************

   For netCDF-4 to work, you must have HDF5, version 1.7.52. You must
also have the zlib compression library, version 1.2.3. Both of these
packages are available from the netCDF-4 ftp site at
`ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-4'.

   You must build zlib first, with the usual:

     ./configure --prefix=/home/ed/local && make install

   Then you build HDF5, specifying the location of the zlib library:

     ./configure --with-zlib=/home/ed/local --prefix=/home/ed/local && make 
install

   Then you build netcdf-4 with the following configure options:
     ./configure --enable-netcdf4 --with-hdf5=/home/ed/local 
--prefix=/home/ed/local
     make check install

   The configure script will try to find necessary tools in your path.
When you run configure you may optionally use the -prefix argument to
change the default installation directory. For example, the above
examples install the zlib, HDF5, and netCDF-4 libraries in
/home/ed/local/lib, the header file in /home/ed/local/include, and the
utilities in /home/ed/local/bin.

   The default install root is /usr/local (so there's no need to use the
prefix argument if you want the software installed there).

   Without the -enable-netcdf-4 argument, the netCDF-4 HDF5 features
will not be available. Without the -with-hdf5 option, netCDF-4 will not
know where to find HDF5.

   By default the netCDF configuration will build static libraries
only. For shared libraries as well, use the -enable-shared option to
configure.
