Does that happen even after you delete the build directory and sta
I am using a GRC flowgraph for testing the energy detection algorithm for
cognitive radio.I want to update my threshold for probability detection by
estimating the SNR of the channel.
However, for this, I need a feedback loop, which I want to know how to
implement.

Hi Sagnik,
right now, you can't build loops out of stream connections. That has
causality reasons – if you had such a loop, and the "merging" block at
the start of the loop would need input on both channels, GNU Radio
couldn't guarantee your flow graph could ever start¹.
If you can live with a lo
How can I receive bits using file sink in ofdm receiver.
where I have to connect file sink in flow graph of ofdm receiver?

A patch was applied a couple weeks ago because gr-dtv wasn't running the
same check for GSL that the previous libraries were (in CMAKE), which
caused the same problem. Perhaps this is the same issue? Really depends
exactly which version you were running. If you are running from git

Hi Muhammad,
sadly, it's not very clear what you're asking about.
* Which flow graph are you referring to?
* What is your precise problem, and what have you tried to solve it so
far? How can we help you with that?
Best regards,

Hi all,
thank you for your input.
Some clarifications:
I was indeed cmaking the latest version from git

and was working from scratch with a clean built.
I attach here the whole output of cmake.

Hi Achilleas,
I'm "able" to reproduce this on Fedora 25. Mh, what a pleasure.
Have you opened a bug report on github for this already?
Best regards,

I would take a look at the FindGSL.cmake script. I suspect the issue is
related to the change to run FindPackage twice. Perhaps the pkgconfig
detection isn't pulling in the variables the second time so they are being
set to nulls?
For a quick test, I would try commenting out the "find_package(GS
