You could add NetBSD 10 the CI farm. (I am not clear on how docker
works.)
It seems this is pretty hard:

https://stackoverflow.com/questions/39130040/cmath-hides-isnan-in-math-h-in-c14-c11
https://developers.redhat.com/blog/2016/02/29/why-cstdlib-is-more-complicated-than-you-might-think
(section "absolute mess")
another possibility is to use __builtin_isnan, which works
on gcc and clang but that's not portable to other compilers that comply
with standards.
From reading lots of things, I have taken away that in C++ code isnan
should always be written std::isnan(), have not found anything
indicating that writing it that way is at all bad, and that it's
unspecified if abs without std:: works or not.

Re: [VOLK] Release 3.3.0
Hey Greg,
thanks for picking up the release so quickly. I haven't seen this issue with any of the CI compilers.
Would there be a way to reproduce that in a docker container?
Cheers
Johannes

Thanks - I am trying to update the pkgsrc entry, and running into a
problem that's awkward to patch.
In include/volk/volk_common.h, there is frequent usage of
isnan
isinf
If the heaader is included by a C program, this is fine.
If it is included by a C++ program, then it appears to mean std::isnan,
but it is not specified if C++ compilers have to allow bare isnan to
refer to std::isnan or not. gcc 10 on NetBSD does not allow this, and
many other projects have fixed isnan to std::isnan (in a C++ context).
The difficulty here is that the header, while marked c++ for emacs mode,
is trying to be both C and C++.
Perhaps the fix is to #if on cpluslus and define our_isnan to
std::isnan and if not to isnan, but I hope somebod who understands C++
better than I do knows a nicer way.

Thanks - I am trying to update the pkgsrc entry, and running into a
problem that's awkward to patch.
In include/volk/volk_common.h, there is frequent usage of
isnan
isinf
If the heaader is included by a C program, this is fine.
If it is included by a C++ program, then it appears to mean std::isnan,
but it is not specified if C++ compilers have to allow bare isnan to
refer to std::isnan or not. gcc 10 on NetBSD does not allow this, and
many other projects have fixed isnan to std::isnan (in a C++ context).
The difficulty here is that the header, while marked c++ for emacs mode,
is trying to be both C and C++.
Perhaps the fix is to #if on cpluslus and define our_isnan to
std::isnan and if not to isnan, but I hope somebod who understands C++
better than I do knows a nicer way.

[VOLK] Release 3.3.0
Hi everyone!
I just tagged the VOLK v3.3.0 release! We want to thank all
contributors. This release wouldn't have been possible without them.
We received a lot of improvements to existing kernels, new kernels,
and optimized support for a lot of existing kernels.
Moreover, a lot more implementations make use of AVX512 now, as well as
more optimizations for RiscV, and more NEON implementations.
Thus, overall this is a very exciting release!
Additionally, we received updates all over the code base to improve code
quality.
Obsolete code was removed, we get closer and closer to being able to
remove the
cpu_features submodule and rely on the distribution package everywhere.
Besides, our throughput test output received a face lift to make it
easier to digest.
Finally, over the years, we discussed in-place kernel operations repeatedly.
While we don't test correct in-place operation, e.g., GNU Radio relies
on it for
multiple kernels. Finding a way to check and document this behavior is
an ongoing effort.

Hi Mididoddi!
Welcome to the community! Great approach to learn about GNU Radio by going through the
tutorials. Let us know here or in chat if anything about the tutorials seems unclear!
Best regards,
Marcus

New GNU Radio contributor introduction
Hello GNU Radio community,
My name is Mididoddi Sai Poojith, and I'm currently a Dual Degree (BTech + MS by Research) student at IIIT Hyderabad, specializing in Electronics and Communication Engineering.
I'm highly interested in signal processing, communication systems, and open-source development, and I would like to start contributing to GNU Radio. I'm also preparing early for GSoC 2026. I want to build a solid understanding of the ecosystem.
As part of my academic background, I've completed relevant coursework, including Signal Processing, Communication Theory, Introduction to 5G, and Architecture of Cellular Systems. I'm also comfortable working with Python, C++, Git, and Linux.
Currently, I'm learning through the GNU Radio tutorials to become comfortable with GNU Radio concepts and workflow.
I would appreciate your guidance on how I can start contributing effectively as a newcomer.
Thank you for your time and guidance.
Regards,
Mididoddi Sai Poojith
