[Discuss-gnuradio] gnuradio/usrp on MacOSX Darwin 8.5

[Robert W McGwier]

There are several documents out and about on how to get Gnuradio built 
and running on MacOSX.

I found it quite a bit easier than some of these documents indicated.  I 
was able to get Python 2.4.3 automatically installed.  WxPython 
automatically installed.  Both of these were from dmg packages available 
for download from the Python and wxPython sites respectively.  The nice 
thing about the wxPython dmg is that it contains a prebuilt wxwidgets 
for OSX.

Portaudio was downloaded using the new svn download

svn co https://www.portaudio.com/repos/portaudio/branches/v19-devel

./configure;make; sudo make install

was done and it just plain comes up and works.  PERIOD, end of story.

darwinports is absolutely imperative

http://darwinports.opendarwin.org/

I installed gcc-4.1.0,  and the usual Numeric, libusb, etc. from the 
build_install list at

http://www.kd7lmo.net/ground_gnuradio_install.html

using darwinports.

I did

./for_all_dirs ../buildit

and then entire thing (with the exception of the "for tars only" bug I 
talked about in an earlier message) just plain built.

I went to

~/gr-build/gnuradio-examples/python/audio

and edited multi_tone.py and changed

from gnuradio import audio

to

from gnuradio import audio_portaudio

down further in the file I changed

dst = audio.sink (sample_rate,

to

dst = audio_portaudio.sink (sample_rate,

and it ran with the usual tones.

Then I did the same changes in

gnuradio-example/python/usrp/usrp_wfm_rcv_pll.py

I did ./usrp_wfm_rcv_pll.py -f 93.3 -V -4

and  WMMR came out of the speakers and the display was as the attached.

It all just worked.

Because of the lack of use of altivec,  it consumes one of the 
processors to 90% in my dual G5 doing the receiver and display.  This is 
not a low overhead application.
