Re: [Discuss-gnuradio] Problem with the bbn code on GNU Radio

[Chen Chen]

Thank you. I have downloaded the douggeiger branch of the bbn802.11, but it still does not work on my gnuradio.

I change blks->blks2, Numeric->numpy,

flow_graph->top_block , that the error occur,

Then another error comes:

Traceback (most recent call last):
  File "./bbn_80211b_test.py", line 124, in <module>
    main()
  File "./bbn_80211b_test.py", line 105, in main
    fg = my_graph(rx_callback, options.spb, options.alpha, options.snr)
  File "./bbn_80211b_test.py", line 56, in __init__
    gain=1)
  File "/home/pl506/bbn_80211/douggeiger/src/examples/bbn_80211b_pkt.py", line 68, in __init__
    self.pkt_input = gr.message_source(gr.sizeof_char, msgq_limit)
  File "/usr/local/lib/python2.6/dist-packages/gnuradio/gr/gnuradio_swig_py_io.py", line 1099, in message_source
    return _gnuradio_swig_py_io.message_source(*args)
NotImplementedError: Wrong number of arguments for overloaded function 'message_source'.
  Possible C/C++ prototypes are:
    gr_make_message_source(size_t,int)
    gr_make_message_source(size_t,gr_msg_queue_sptr)

 
Is this the bbn80211 code not compatible with the gnuradio? Thank you

CGRAN is kind of up...

https://128.2.212.19/

our CS department got a new building, and our machines got re-assigned
IP addresses when the machines were moved.  I've asked Eric to update
the DNS record for cgran.org, hopefully this goes through soon!
