Re: Cannot resize GRC window panels

2023-02-15 Thread Ryan Volz

Hi,

And now the conclusion to this riveting saga...

Further investigation has revealed that the problem is that the drag 
indicator icons were not being found with the conda xorg-libxcursor 
package installed. You can still actually click and drag to resize the 
panel boundaries, there's just no visual indication. This happens 
because installing that package causes X11 to look for cursors in the 
conda prefix but not the system prefix, and unless you're using the 
Adwaita theme it won't find them.

You can set the XCURSOR_PATH environment variable to point to your 
system cursor installation (probably /usr/share/icons) to get things 
working properly again:

export XCURSOR_PATH=/usr/share/icons:/usr/share/pixmaps
gnuradio-companion

I also have a fix to the xorg-libxcursor package so that it will fall 
back to the system directories when looking for cursors. That should be 
rolled out soon so that the environment variable workaround is not 
necessary after an upgrade.

Cheers,
Ryan

So if you don't need gr-fosphor, you can `mamba uninstall 
xorg-libxcursor` as a temporary workaround.

It shouldn't be strictly needed anyway since things will fall back on 
using the Xorg libraries from outside of conda, but for some reason it 
is a requirement of the glfw3 package. Now I'll have to investigate 
either fixing xorg-libxcursor or removing that dependency.

Re: Issue with UHD and GNUradio

2023-02-15 Thread Marcus Müller

Hi James,

as I just commented somewhere on the internet [1] (was that you? Hi :) !), unless you
really have a reason to use more modern version of UHD, you would use an image that fits
the UHD host side, and not the other way around.

Assuming you do have a specific need for a specific version of UHD: So, you need to have a
GNU Radio that was *build* against the right version of UHD. You can't "change GNU Radio"
after it's been built to work with an incompatible version of UHD!

Sadly, you did not mention how you installed your UHD and your GNU Radio – a bit hard to
help you like that! But, as a rule of thumb: If you're already in the process of changing
parts of your software infrastructure, it's a good point in time to update your Ubuntu to
at least 22.04 LTS.

Which version of UHD do you need? How did you install that version?

Best regards,
Marcus

I'll note that Ubuntu 22.04 has more-recent versions of both GR and UHD:

GR  3.10.1.1
UHD 4.1.0.5-3

You didn't mention which USRP you have -- for some of them, there 
haven't been any meaningful updates in at least

  a couple or three years.   So older UHD will be just fine.

Re: MPSK SNR Estimator Probe

2023-02-15 Thread Marcus Müller


Hi Symon,

As explained in our FAQ[1], you need to have a source of known power and observe it. Then 
you can put your observation of signals of interest into relation to that.


In this case, you'd need a reference transmitter for PSK of known power at your receiver 
input.

Marcus

I have a problem when trying to measure noise/signal power. I have been trying to use

What type of calibration is needed and what is actually measured by this block (what is

double free or corruption error when two instances of an OOT block is called in GRC

2023-02-15 Thread Grace Yeung

Hi, I have a gnuradio out-of-tree block written in C++ that runs fine in 
grc 3.8.1.0. But when I have two of them running simultaneously in the 
flowgraph, grc crashes and gives me the error:


double free or corruption (!prev)

I am not using any free() functions. I use std::vector's in my code 
which should handle dynamic memory allocation automatically. What could 
be causing this error?


The only other place I see in the code that deals with pointers is the 
calling of "new" in the definition of the make function which returns an 
sptr:

  probeExtract::sptr
  probeExtract::make(const char* filtName, const char* maskName, 
int mlsrM, int numChan, int sampPerBit, int Tblock, int edgeBufferSize, 
int structureType)

  {
  return gnuradio::get_initial_sptr
  (new probeExtract_impl(filtName, maskName, mlsrM, numChan, 
sampPerBit, Tblock, edgeBufferSize, structureType));

  }
I suppose I do not need to worry about free'ing the pointer which is 
handled internally by python?


After putting in some debugging statements, I see variations of similar 
error such as:

corrupted size vs. prev_size while consolidating

Any advice would be greatly appreciated. Thank you.

Grace
