[netCDF #FYL-827092]: HDF5

Hi Pedro,

> Does netCFD needs HDF5?

It depends on what you're using netCDF for.  NetCDF-4 software
can be built with only support for the classic netCDF data model
and formats.  In that case it won't need HDF5, but it will read
netCDF-3 classic data fine, and be able to write new netCDF files
that conform to the simpler netCDF classic data model.

If you need any of the features supported only by the enhanced
netCDF data model, such as reading or writing compressed data,
chunking (also called multidimensional tiling), multiple unlimited
dimensions, additional unsigned primitive data types, real strings,
or user-defined data types, then you will need an HDF5 library.

Here's a short presentation on the differences:

and here's an FAQ on the differences:

To build without HDF5, see the section on building with the classic library 
only
