Yes, it's entirely possible (expected even) that a file created by the
HDF/netCDF library via the `netCDF' API will not be accessible by the
UCAR netCDF library. The HDF/netCDF library puts a netCDF API "veneer"
on top of their HDF library: the underlying file format is still HDF.
(The HDF software people at NCSA liked the netCDF API.)
The user will have to re-link their utility against the HDF/netCDF
library in order to access the file.
