[GR-UHD] Announcing GNURadio 3 binary installers with UHD 4.9

Hi All,

 

Together with the latest UHD 4.9 release new GNURadio 3 binary installers with UHD 4.9 support are now available for Ubuntu and Windows.

 

Ubuntu Noble (24.04), Plucky (25.04):

- GNURadio 3.10.12

- https://launchpad.net/~gnuradio/+archive/ubuntu/gnuradio-releases

 

Windows 10/11:

- GNURadio 3.11 (based on https://github.com/gnuradio/gnuradio/commit/721e477)

- https://files.ettus.com/binaries/gnuradio/latest_stable

Note:   The Windows installer bundle uses cmake changes not yet available in gnuradio main and has received limited testing outside of using grc with gr-uhd required features. Please refer to https://files.ettus.com/binaries/gnuradio/latest_stable/gnuradio_installer_README.txt for other known limitations.

 

Thanks,

Marian Koop

 

 

Re: Simple BPSK Constellation?

Ralph,

It's because the Constellation Modulator includes a root-raised cosine filter. If you just want bare constellation points, you can use the Chunks to Symbols block.

Hi Everyone,

I've been trying to make a simple DBPSK transmitter for a random data (bit) source in GRC. My flowgraph just uses:

                        Constellation Object
Random Uniform Source > Constellation Modulator > Throttle > QT GUI Sink

However, in the constellation plot I see clusters around -1,1 and a point at 0,0 instead of the expected tight grouping just around -1,1. I've confirmed the source produces a stream of 0,1 (bytes) so there should be no errand points being mapped to 0 etc. Can someone point me in the right direction?

Thanks,
Ralph

Re: binding errors in Ubuntu 24

Federico and all,

I've found a better solution for this issue (a little late, but better than never). If you use the latest version of castxml, the massive error problem is solved. Here's the steps:

1) Download the latest pre-built version of castxml at:

https://github.com/CastXML/CastXMLSuperbuild/releases

For Ubuntu 24.04, I used:

https://github.com/CastXML/CastXMLSuperbuild/releases/download/v2025.09.03/castxml-ubuntu-24.04-x86_64.tar.gz

2) Install the tar.gz file into any directory.

3) Set a path to the newly installed castxml binary. For example, I installed into /media/re/nvme/castxml:

export PATH=/media/re/nvme/castxml/bin:$PATH

gr_modtool bind now works good.

Hi, 

Thanks (publicly) to Ron for his solution, it worked like a charm. For anyone finding a similar problem, I've used a Docker with a 22.04 Ubuntu (you may use mine at https://github.com/git-artes/docker-gnuradio/, although there are several other out there), migrated the OOT through the required gr_modtool bind, and it also worked perfectly in my "native" 24.04.

I just tried gr_modtool bind on Ubuntu 24.04, and I'm getting the same
results (huge error dump).

For the last OOT I updated to 3.10, I just went back to Ubuntu 20.04 and
gcc 9.4.0. Then I checked that it builds okay on Ubuntu 24.04.

I've pasted my Ubuntu 24.04 gr_modtool bind error dump onto the end of
this e-mail.
