The problem was that I had built FFTW wrongly, according to the installation
guide, and then all the examples that used USRP did not work, returning only
Segmentation Fault ("Falha de segmentação", in portuguese).
After the correct building, all the examples worked perfectly.

I built GNU Radio yesterday, and I can't run the USRP examples.
It returns the message: "segmentation fail" and the USRP examples do not
work.
Audio examples run normally.
Thanks,

Hi Thomas,
nice to see someone in the gnuradio world treating with the same problems.
In my case the cc1k send 5 preamble bytes (0x) followed by a
synchronisation sequence of 0x. After this comes the header and my data.
The synchronisation sequence of 0x is the chip pattern of transmi
Just committed an update to HF Explorer 2 in
gnuradio-examples/python/apps/hf_explorer/hfx2.py
which implements synchronous AM detection. The
center frequency gets shifted to 7.5kHz in AM and
you can definitely hear when the PLL 'locks' onto
a carrier. Seems to work.

John,
Try this:
...
from gnuradio import gru
...
mux = gru.hexint(0xf0f0f0f0)
...
It works for me...

Eric,
I haven't been able to reproduce the problem yet, but I'll keep an eye out and let you know if I can.
When I ran into ther problem, my machine had been up for a few weeks
and I'd been doing some heavy development on it. I was building a
program linked against libusrp (not surprisingly, my

Portaudio is really solid on Windows as I have been using it there for
ASIO, MME, and DirectX for two years and after I helped Eric Wachsman
get a leg up (by leaning on my friends for help) he got WDM-KS
Sunflower:
the correlator may be used. You may also use the filtering routine by
making the appropriate changes to the waveform you wish to cross
correlate against the incoming signal such as reverse in time and
complex conjugate. What are your needs?

I guess that, being the array approach the one used in c++ blocks, that
would be the best to use in python as well. So I would definitely work
with input and output arrays.
