Hello to the group,
Having a problem with installing gr-osmosdr. I'm trying to have gnuradio
recognize my RTL-SDR dongle (RTL2832U R820T2). The following error happens when
using any command starting with rtl_xx or using gnuradio companion 3.7.9. This
is all under Ubuntu 14.04.

Can you rerun pybombs with the debug output enabled?

Hello Rob,
I haven't used PyBOMBS so can't speak to the exact error there. Your OS has
stopped supplying the 1.53 Boost packages, however installing one of the
later versions of Boost manually will likely allow the process to go
forwards. Can you try installing 1.54 and then rerunning Boost?

Hi,
I just setup a new system and as I attempted to install UHD via PyBOMBS, I
stumbled on the PyBOMBS 2.0 changeover. Since I typically only follow the
usrp-users list and not the gnuradio list, I didn't see the announcement of
this changeover.
I am having trouble with the install. I really am
Hi,
Can anyone help me set the maximum output number of items within the C Code of
a GNU Radio OOT block ? I am trying to set this to a single sample as its a
decimating block and I need the next block to retune at specific sample times
whilst controlling the scheduler to limit the size of data
The problem is not the length 2048 but the way you use the fsm constructor
trellis.fsm(2,7,[79,109])
You are trying to create an FSM for a (7,2) CC.
This means you need to provide a vector of 2x7 integers, each
representing the generator polynomial between the i-th input (i=0,1)
to the j-th ou
Hi,
I have a hierarchical block generated via GRC with no input or output
message port.
Now I add a message port by changing python code for some control
functionality using:
self.message_port_register_hier_in("test")
Now generally in sync or other blocks we can bind this "test" port to
The "build-gnuradio" script pulls from master by default, so that's why the
UHD version number appears as it does. It's newer than the most recent
tagged release, which is version 3.9.2.
You should ideally use only tagged releases of UHD. To tell the
"build-gnuradio" script to use version 3.9.2, i
I was installing GNU Radio and UHD using build-gnuradio script. I see that
the changelog of UHD at
https://github.com/EttusResearch/uhd
says that the latest release is 3.9.2 but the script installs
UHD_003.010.git-119-g42a3eeb6
What I am missing here ?

Hi Salija,
yes, of course that is possible! This is Free and Open Source
Software[1], after all :)
I think you should read the guided tutorials [2] first; they give an
introduction on how to implement a block of your own. Since GNU Radio's
"in-tree" blocks are structured like the ones you learn t
