That's a hint that there are no parsers available at all.

I looked at the win32/raptortest.cpp code - which was last modified
in 2001, and not by me.  The code looks particularly dubious.

The bug seems to be that the parser library isn't initialised (or
terminated).  If you add a raptor_init() call before any call to the
library, it might work now.  (raptor_finish() before exit too).

More docs and a summary at the top of
 http://www.redland.opensource.ac.uk/raptor/libraptor.html

The rapper utility, although not in C++, is the best example code
of how to invoke the parser standalone.  See rdfdump.c in the
sources.
