My problem is when I use gr_uhd_usrp_sink_sptr usrp_sink = uhd_make_usrp_sink(addr,type,1); but its error information is:'gr_uhd_usrp_sink_sptr' was not declared in this scope. And I read the source code from the URL: http://gnuradio.org/cgit/gnuradio.git/tree/gr-uhd/lib, the class uhd_usrp_sink has many pure virtual functions and it inherited in python, in the source code uhd_swig.py, how can we directly instantiate uhd_usrp_sink in C++? Due to my unfamiliarity with C++ and maybe it looks a bit ridiculous, Hey! Thanks very much for your help in advance! -- Ding, Yuzhen Best Regards!
