Marcus, the repo at https://github.com/giladbeeri/gr-uhd-link-test
is a bootstrapped OOT module with basically nothing but a simple block that
has a single uhd::time_spec_t member.
I can reproduce the linking problem with this repo and a clean GR 3.7.12
(from master) install using pybombs.

Did, but hm, works for me :( Attaching the ldd output.
Is UHD installed through your package manager or through pybombs? Can
you locate all libuhd.so.* on your system?

Any chances you are confusing libgnuradio-uhd.so with libuhd.so. To me
it sounds like you want to link against the latter.
Maybe some linkers resolve symbols from libuhd through libgnuradio-uhd
and some don't (which might make sense if you do not use any symbols
defined in libgnuradio-uhd).
That's normal FIFO behaviour! From `man 3 mkfifo`:
> Opening a FIFO for reading normally blocks until some other process
opens the same FIFO for writing, and vice versa.
Remember, the GRC file is just converted to a Python program, in which
the different blocks are instantiated sequentially.
Basti applied hammer to nail's head. It's (probably) super effective.
yeah... time_spec_t's functions aren't exported symbols of libgnuradio-
uhd, but of libuhd! This might work on some and not on other build
systems due to different handling of visibility of symbols *used* in a
library. uff!

Yay, it works!
Thank you, Basti and Marcus :)
So the only change I needed to make for my build system is to find the
first target_link_libraries() under lib/CMakeLists.txt and add both
${GNURADIO_ALL_LIBRARIES} and uhd to the list (both are required). I did
not have to add anything to the link li

This sentence makes no sense on its own. Please post a whole
description of what you're doing: I'll from now on will ignore your

I had this after the last bigger changes, maybe two weeks ago or so. Went back
to maint, all was fine, forth to master, and again the issues. Deleting the
build folder did not help, but deleting the whole gnuradio folder and doing a
new git clone helped.

Hi All,
I have installed gnuradio from source as instructed on gnuradio webpage. I
have Ubuntu 18.04 on my host PC. I can ping USRP x310 and can also do
uhd_find_devices, however when I use "uhd_usrp_probe --args
"addr=192.168.10.2" it return FPGA compatibility issue. In repose to this I
have done

Hello everyone,
GNU Radio Conference is coming up in September. If you haven't registered
and want to go, please do at https://www.gnuradio.org/grcon-2018/
There's a special event this year called Block Party.
It's an effort to get DVB-S2 and DVB-S2X receivers in GNU Radio.
We will have our own
Hey,
I had the same problem a few weeks back in a two channel scenario.
I ended up writing a simple python 'gate' block that passes a
configurable amount of samples for every pulse on the trigger input.
It is super inflexible and hacky but should be fairly easy to modify.
I quickly moved the
I'd suggest incorporating RFNOC at least as an option. I suspect actual use
of DVBS2X might be rather boring if you're stuck on a processor.

Hi all,
after a while of testing and gathering feedback, we have merged the UHD
Python API into master branch. In general, we are happy with its state,
but that doesn't mean it's perfect and complete.
First off, there's at least one known issue with the Python API: It does
not build on Windows. W
Hi all,
there's another project call coming tomorrow 10 AM Pacific, or 19:00 EU
time. I'll send out coordinates closer to the call, if you want to join,
come to #gnuradio on Freenode or Slack.
Cheers,
Martin
