Hi all,
I have made an OUT-OF-TREE module, but now I want to remove it from
gnuradio. I am using GNUradio 3.7.3. Can anyone tell me how to that?
Thanks a lot

Hello Marcus,
I'm aware of that, what I want to achieve at the moment is simply to
have a predictable phase delay between the tx and rx channels. This is
prerequisite to measure the round-trip time and account for it.
Cheers,

Hi Daniele,
Hey,
If you use the Echotimer you can use the same IP vor TX and RX, this
should work.
Probably you can do your own USRP Sink/Source with UHD. You dont need
much code to implement this (Echotimer ~300 lines in the *impl.cc). Main

Martin,
You are probably right we should track maint by default at this point.I
think it's worth adding a Pybombs environment question about which branch
to track during initial setup for those that prefer to track master
however.

You can verify this by looking at the install_manifest.txt in your OOT's

As UHD and GNU Radio are widely independent, you can use whatever
combination you want in almost any situation (aside from severe API
breakage).
Thanks.

One of the problems with allowing this kind of customization is that a
single set of pybombs recipes is generally intended to represent a fixed
set of versions / branches as far as configuration management.
Supporting additional branch combinations is kind of explosive in terms

So, is there any difference between *sudo gnuradio-companion* and

Yes, the sudo part ;)

Indeed, the only reason to run things under "sudo" is when you're doing something that needs root privilege, like updating system files
(such as when you do a sudo make install), or you're trying ot get access to some resource that an ordinary user doesn't have access to.

Hi John,
I think you're on the right track:
you use gr-fft in your code, but then don't tell your linker to link
against that, which leaves your libgnuradio-comso missing the symbols
from gr::fft, which breaks linking test-comso.
So what you need to do is edit your CMakeLists.txt in your
Ah, by the way, look for gr-specest [1]; you can look at it as an
example of using gr-fft, fftw itself, some more gnuradio modules, and
the idyllic language called fortran in an out-of-tree module.
