Hi Jack,
There are two different, non-compatible netCDF C++ releases, and I suspect
you may be trying to use the new netcdf-cxx4 library on code intended for
the legacy netcdf-cxx release. You can still get, build, and install the
legacy release, but it is no longer being maintained or supported. See this
download site <http://www.unidata.ucar.edu/downloads/netcdf/> for either
version.
The newer netcdf-cxx4 software, contributed by Lynton Appel, is not
designed to be backward-compatible, but provides the benefits of a modern
C++ library with its use of name spaces, exceptions, and templates. The
legacy API used none of those, and it is impractical to upgrade in a
backward-compatible way to also provide support for the netCDF-4 enhanced
data model.
In case you want to upgrade to the netcdf-cxx4 library, the latest version
<https://github.com/Unidata/netcdf-cxx4> of the source has significant bug
fixes and other improvements over the current release available from the
legacy Downloads site referenced above.
