Re: '*****' has not been declared

Hi Nik,

if you use names from a different header file, you'll need to include that header,
otherwise your compiler can't know what that name means! In this case, you need to include
the header that defines gr::digital::constellation and gr::digital::constellation_sptr.
That would be done by

#include <gnuradio/digital/constellation.h>

in your header.

(note: that's a bit of a basic C++ thing, you need to declare the things you use in each
compilation unit *before* you use them.)

Best regards,
Marcus

PS: kind of surprising to pass in both a shared pointer to a constellation object, and to
pass-by-value (i.e., make a copy) another constellation object. Hope that makes sense!
