Re: [VOLK] Release 3.3.0

Hello Greg,

would you mind giving https://github.com/gnuradio/volk/pull/813 a try on your machine, please?

Hello Johannes,

sadly I could not find a way that both introduces no random new includes in volk_common.h
that causes functional changes in consumers of the header, while still addressing the
issue Greg describes; the cleanest seems to be moving the mostly-internal math functions
out of volk_common.h to a new header.
That of course means API breakage; sorry.

Best regards,
Marcus

Sure, please feel free to @gdt (github and codeberg) or email me a link
and I'll try it.

Johannes: I realize that having bougght into github CI that it's not a
great portability situation as the set of available runners is very
limited. I am struggling with this myself on an unrelated project, but
so far more inclined to put energy into leaving github and some
beyond-github future CI more than improving CI on github, even if it's
not so much either way :-(

Someone else updated volk to 3.3.0 and here's the patch they arrived at.
I'm not a fan of doing it this way (upstream), but it does more or less
show the issue well.

Re: [VOLK] Release 3.3.0

Hey Greg,

Our CI consists of the GitHub runners that are available through this channel. If there's a service to add netbsd runners, please let me know. That'd be a great addition.

Besides, Marcus suggestion to fix things sounds good either way.

Cheers

Re: [VOLK] Release 3.3.0

hm that volk_common.h is generally not that well-structured; I'd advocate for having
something like `volk_cos_poly` in a different file than basic type and attribute
declarations that get used all over the place. I'll make a PR to that end; if you could
test that, Greg, it'd be much appreciated.

You could add NetBSD 10 the CI farm. (I am not clear on how docker
works.)

It seems this is pretty hard:

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

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.

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.
