Hi Michael,
I noticed something weird, and was wondering if you've
come across this already
when using qt-4.7 cocoa 32-bit only, qwt, qwtplot3d, sip and pyqt4, and
building gnuradio, the linker incorrectly attempts to link to the Carbon
libraries,
h ../../../libtool --
Hi,
Where can I control linker architecture flags to prevent the following
errors? I've built qt, qwt and qwtplot3d for 32-bit mode, and with cocoa
support.
However, at link time, gnuradio is trying to link to x86_64.
A little futher down, it is trying to link to the Carbon framework,
you will have to make the constellation a 2D array (essentially representing
the 2 BPSK symbols).
It is all explained in the examples and the documentation of gr-trellis and
in the examples...
please read it; i spend a lot of time writing it...

Hello Achilleas,
I made changes to vector source and sink, encoding works fine with
awgn1o2_128.fsm.
But the result of encoder is 2 bit packed and is not suitable for me.
Since i want to employ BPSK modulation (0-> -1 / 1 ->1), I need encoder output
1 bit at a time.
Since awgn1o2_128.fsm dicta
Hi, All,
In my current design, frequency hopping is designed to happen over
32MHz bandwidth, as fast as possible. (although I admit that by using
USRP1, it may not be that fast as I expected). However, I am not very
clear about how to do so.
I checked the implementation of bluetooth (gr-bluetooth
Hi,
I have installed the GNU Radio Debian binary library (3.2.2) on my laptop
running Ubuntu 10.04. Is there an easy way for me to make minor changes to

Thank you,
Tuan

Sorry for bringing up an old thread. I was having the same problem of not
receiving packets using benchmark_ofdm_* and changing the receiver frequency
to tune to the transmitter frequency indeed solved the problem.
However, if I have to manually do it every time, I don't see how I can get

As I mentioned in my earlier email, you have misunderstood the functionality
of the

block. It takes a vector "vec" as an argument and produces A STREAM OF
SHORTS at its output!!!
It is NOT producing a stream of vectors at its output...unless you specify

Thanks for your response.
I have connected encoder block , it disappeared during editing mail by mistake.

Use the provided 'bootstrap' routine, but remember to change the
'libtoolize' call to 'glibtoolize' or whatever you named that function
on the version you installed yourself. If you used MacPorts to
install GNU Libtool (of which 'libtoolize' is a part), then it
prepended the 'g' for you.

I also realized that the way you call
gr_make_vector_source_s(in_bits,false,K );
is incorrect.
I think you have misunderstood what this block does.
You should use:
gr_make_vector_source_s(in_bits,false,1 );
or simply
gr_make_vector_source_s(in_bits,false);
and you really don't need the vector2s

Hi,
I've got Qt-4.7 installed, and the paths set in my .profile. I've also
run and tested PyQt4 and it works with the Qt-4.7 installation.
When I run gnuradio configure, I get the following message:
checking for PyQt4 for Qt4... yes
checking for QTCORE... no
gr-qtgui requires libQtCore
I was thinking of putting them in different top blocks, but maybe
that's not possible, I don't know.

Thanks, that worked now.

The hier_block2 blocks do not have start/stop methods, and I can not stop

Apparently a newer vesion of GTK supports Mac OS X's quartz backend, bypassing

For python scripts you change the defaults by modifying:

For the four blocks change std::string ifc="eth0" to std::string ifc="eth2"
and recompile
