I have tried to make a new signal processing block which that is called divcom. It is a diversity combining technique used to mitigate the effects of multi-path fading. I am trying to implement this algorithm using GNU Radio.
I made my signal processing block and I now wish to integrate this to the GNU Radio's library. Unfortunately, I always get the following error message upon "MAKEing" (The message below is truncated.) divcom_rca_ff.cc: In function 'divcom_rca_ff_sptr divcom_make_rca_ff(const std::vector<float, std::allocator<float> >&, const std::vector<float, std::allocator<float> >&, const std::vector<float, std::allocator<float> >&)': divcom_rca_ff.cc:38: error: cannot allocate an object of abstract type 'divcom_rca_ff' ./divcom_rca_ff.h:45: note: because the following virtual functions are pure within 'divcom_rca_ff': /usr/local/include/gnuradio/gr_block.h:113: note: virtual int gr_block::general_work(int, gr_vector_int&, gr_vector_const_void_star&, gr_vector_void_star&) make[4]: *** [divcom_rca_ff.lo] Error 1 I did the steps found in this website ( http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html) and I just changed a few bits of the code. My question therefore is this. Could I not allocate a NEW CLASS TYPE (in this case divcom_rca_ff) since the function general_work from the base class gr_block is a PURE VIRTUAL CLASS? Thanks!
