Re: [Discuss-gnuradio] Cannot build USRP. ./configure reports sdcc is missing in spite of it being installed!

Hi, I tried these and it fixed the problem. ln -s /usr/bin/sdcc-asx8051 /usr/bin/asx8051 ln -s /usr/bin/sdcc-aslink /usr/bin/aslink Earlier I had tried exporting /usr/libexec/sdcc to PATH, but that didn't fix it. Thanks, Arya On Wed, Nov 10, 2010 at 7:24 PM, Eric Blossom wrote: > On Wed, Nov

Thanks Josh! Problem solved after I adjust the bit rate. One more question, what is the maximum bit rate in USRP1? Also, what is the default sampling rate in benchmark_tx.py and benchmark_rx.py? Based on Nyquist theorem, the sampling rate should be at least twice of the baseband bandwidth, is the

Thank you so much for your reply, Steven. I tried to use gr.message_source to push the new data into the msg_queue? As my understanding, the msg_queue push new data by using msg_queue.insert_tail(gr_message_sptr msg. The new data pushed into the msg_queue need to be the type of gr_message_sptr. How
