Hello, I git cloned the atscfixup branch and tried building it. Here's as far as I got:
In file included from /users/mranga/gr-atscfixup/gnuradio/gr-atsc/lib/receiver/atsc_fpll.cc:27: /users/mranga/gr-atscfixup/gnuradio/gr-atsc/include/gnuradio/atsc/fpll.h:32:44: error: gnuradio/atsc/diag_output_impl.h: No such file or directory Perhaps this file was accidentally left out of the repository (?)
