Hello,
Over the past few days, I've learned a lot about installing UHD and GNU
Radio on Ubuntu. I'm a Windows user new to Linux, so there were a lot of
growing pains. I made a guide for people like me out there getting into GNU
Radio and Linux for the first time. I tried to document every single
Just a follow up on this - I was able to resolve the issue with the
following modifications in the volk_config file:

Dear all,
I found most existed projects were based on USRP2 and some current on-going
project are using N200/210. It seems to me that both of these two models
have similar hardware specification, but USRP2 is out of market, isn't it?
If a GNURadio based software packages was developed for USRP2,
I've seen this comment for a while now in flowgraph.cc and most of the time
chose to ignore it. Today I saw it and decided to do a quick google search
to see what I could find.

Funny easter egg to say the least...

Hi all,
I recently installed GNURadio on two laptops (installation via PYBOMBs) and
everything has been running fine for a few weeks; but I'm suddenly running
into issues with QT GUI on one of the laptops. I wasn't sure what the issue

As pointed out elsewhere [1], you can work around the libxml2 issue by running
GRC while forcing MacPorts’ libxml2 library to load first via:
{{{
DYLD_INSERT_LIBRARIES=/opt/local/lib/libxml2.dylib gnuradio-companion
}}}
And, otherwise, both UHD and GNU Radio seem to work on 10.10 beyond the
I'm still asking for help with this maintenance process. I tried the
'./pybombs remove' command to get rid of uhd and gnuradio as a test. I
didn't get any error or warnings and it completed. When I looked in the
pybombs/src folder, both gnuradio and uhd folders still existed there. I
deleted them

Jiayi,
if you were using UHD, you'll be fine. Apart for device-specific
settings, you can simply switch hardware.
Cheers,

i was working in BPSK mod/demod and i'd like to see the BER performance. i
used the BER ERROR RATE block, connecting in the input 1: random source and
imput 2: output of the decodec. The problem is that the error always is 0.5
and the source noise (connected in the mod,) doesn't affect it.

Hi Jiayi,
all USRPs use the UHD driver framework; from an application's perspective, it
really doesn't matter whether you're using a USRP 1, 2, N200, X300, B200 or the
integrated radios of the E-Series. Normally, applications do not even care what
kind of USRP is connected :)
The only thing
Hi,
I've installed the GNURadio UHD correctly. However, I can't use my USRP
because I don't have installed the UHD module in my tree of modules of the

But I can see in the path of the file system where GNUR is installed the
folder named gr-uhd where are all the files related to

Generally, the UHD driver hides the difference, so the Ettus products
are interchangeable. There aren't too many projects that are specific to
model, unless you're looking at FPGA mods. But there are some
differences (or there wouldn't be separate products) having to do with
frequency

A fix has been generated and pushed to the maintenance branch, and will
become part of the 3.7.5.2 and 3.7.6 releases.

Alles klar, Herr Kommissar is kolloquial German for all is good,

The BER error rate block does not realign data from its inputs. Experiment
with different delays between the reference tream and the demod stream to
account for FIR filters, clock recovery process, etc. Note, due to the
nature of symbol recovery, the delay may not be the same every time.

This is because the version of the libusb library you have is too old to have
that particular API call in it.

Do you what version of libusb is compatible?___

I think that 1.0.9 and newer are compatible.

I'm a bit conflicted -- the missing symbol looks like it should belong to

This might indicate that you're bound to update libudev, which is rather system

I have an application that uses two probes/function_probe blocks
and an xmlrpc client.
Most of the times I see that the two threads are crushing, I guess making
concurrent requests to the SimpleXMLRPCServer.
I googled it and I found that the SimpleXMLRPCServer cannot by default
handle these
If I was forced to make a wild guess I'd probably assume it uses some USB-HID
interface for configuration, and udev for hotplug detection.
I think I'll have the libery of including Mr. Schroer in this discussion :)

HI Achilleas,
You could just write your own class that does that, and modify the imports and
make in the .xml. BUT then you yourself are in charge of making sure you don't
concurrently access block members in damaging ways.
However, these crashes you see are suboptimal. You should maybe file a
What I find strange is that the symbol error is found at runtime and
not at link-time. That suggest either there is two libudev and the one
used for runtime is different than the one found for link-time, or
that this library was copied over from another system.

Sylvain
Oh indeed, good point!
Sylvain: you're right.
How gr-fcdproplus ends up being able to compile and link is still a mystery to me. I was
expecting a horrible symbol export forwarding hack involving libusb, but no:
$nm -D /lib64/libusb-1.so
U udev_device_get_action
Tracing this down; Daniel, could you share what
pkg-config --static --libs libsub-1.0
says?
in your build directory, can you do a
