I am here again. I ran "fecapi_async_decoders.grc" with controlport performance moniter on. I made a new config.conf file in ~/.gnuradio and added following lines to it
[ControlPort] on = True edges_list = True [PerfCounters] on = True export = True When I ran the flowgraph I got the following error Executing: "/home/sdr/gr_examples/gr_fec_def_ex/fecapi_async_decoders.py" Using Volk machine: avx_64_mmx_orc ControlPort Monitor running.
