    9 Please note that with CygWIN you need to be sure that the DLLs
    10 are executable, or GDAL will not execute. Use the command {{{ chmod a+rx [NetCDF DLLs] }}}. The netCDF DLLs directory must be in your PATH.

    1822== Improvements to the NetCDF driver ==
    1923
    20 The newer NetCDF-4 library offers features such as per-variable compression (using the deflate algorithm) and chunking which require the HDF5 library. To enable this, "--enable-netcdf4" (and perhaps --with-hdf5=<path_to_hdf5>) must be added to netcdf configure.

    2226The development version of the driver (1.9-dev in svn or nightlies) adds support for NetCDF-4 file format, as well as the 64-bit offset file format.  HDF4 and HDF5 files are also supported, although the respective driver is used if available.  The syntax "NETCDF:<file.hdf>" forces the use of the NetCDF driver.
