[netCDF #PPE-116333]: Can't find or link to the z library

Hi Michael,

Check if your HDF5 library was built with zlib.  The easiest way is to look in 
the libhdf5.settings 
file in the same directory where the HDF5 library is installed, and search for 
the line

         I/O filters (external): deflate(zlib)

which might also have other filters in addition to zlib, but if it doesn't have 
zlib, you'll have to rebuild
HDF5 with zlib support.

Also, you need to indicate where to find the HDF5 library, using CPPFLAGS and 
LDFLAGS environment 
variables, as described in 

    
http://www.unidata.ucar.edu/netcdf/docs/getting_and_building_netcdf.html#build_default

Note that the "--with-zlib=..." configure option you used is not supported by 
the netCDF-4 configure, 
as it's not listed in configure --help output.  Instead, zlib must be found 
either in a default system
directory or in locations listed with the CPPFLAGS and LDFLAGS environment 
variables.
