Re: Reminder: SigMF Workshop this Thursday Noon Eastern

[Derek Kozel]

Alex, yes the workshop will be recorded and posted onto the YouTube
channel. It wasn't feasible to record the in-person one during the GNU
Radio Conference so this virtual one was arranged to be available to a
wider audience. Happily this also means the new workshop can cover the
as-released 1.0.0 spec.

Cinaed, the spec and libsigmf library have been updated to the 1.0.0
version but work is continuing to update the gr-sigmf module. Once that
update has happened we'll be upstreaming it for inclusion in the GNU Radio
core, probably in an update to the 3.10 release series or possibly in 3.11
depending on when the work is complete. I don't think the workshop is going
to substantially dive into using gr-sigmf hands on but focus on the overall
file format and features available in it.

gr-sigmf has been developed by SkySafe and lives under their org's account.

module SWIG disabled when running cmake

[Michelle]

Hello,
I am writing my own block and when I executed /cmake ..// I get the 
warning "/Disabling SWIG because version check failed/".
then when I did the qa test I get the error "/ModuleNotFoundError: No 
module named 'signalSource_swig'/ " (signalSource is the name of my module).
Do I have to install a new version of swig? My concern is that this new 
version could interfere with the proper functioning of gnuradio.

Please could you give me some guidance?
Thank you.

To understand your concerns: you already have a version of swig installed, which you used 
to build GNU Radio?


Best regards,

UHD 4.1.0.5 released - clarification

[Aaron Rossetto]

Hello GNU Radio Community and friends of UHD,

A few weeks ago, I announced that UHD 4.1.0.5 had been released. I wish to
issue a minor clarification to some of the text in the release announcement
message.

I said, 'UHD 4.1.0.5 adds support for the NI Ettus USRP X410 Rev G, which
uses a different CPLD on the motherboard than previous revisions.' That
should have read '...adds support for the NI Ettus USRP X410 **module
revision E with motherboard Rev G**...'. Despite the minor clarification,
we continue to strongly recommend that **all** USRP X410 users regardless
of module revision upgrade their devices with the filesystem that ships
with 4.1.0.5, the instructions for which can be found under 'Updating
Filesystems' in the USRP X4xx section of the UHD manual at
https://files.ettus.com/manual/page_usrp_x4xx.html.

Thank you, and happy New Year!

Best regards,
Aaron

No, it's only necessary for *building* GNU Radio binaries (For GNU Radio 3.7 
and 3.8).

When I execute 
locate swig I get the output below so I must have a version of swig. 


No, these are just swig bindings, not the swig program itself.

However when I 
execute swig -version I get "Command 'swig' not found, but can be installed with: sudo apt 
install swig".

So I don't know what to do.



Install swig :)

Hi Michelle!
looking at this:
have you re-run cmake, and make, before doing ctest?
