I guess the work function is exposed in your interface header? That
should be ok, but you will either need to %ignore your_block::work or
%include <gnuradio/block.h>

Try adding these includes to the top of your file
#define GR_EXTRAS_API
%include <gnuradio.i>
%include "extras_factory.i"
%include <gnuradio/block.h>
Post the error w./ swig .i file if its not working:
