Hi Lance,
I'd been holding off installing Debian 12 because I routinely rely on
X11 for remote access.
Sorry to hear the the X11<->Wayland wrapper is not quite ready for prime
time.
Linus was, as usual, spot on in his lampooning the lack of binary
compatibility in Linux user space.
While it might be understandable that not all Fedora/Redhat binaries run
under Ubuntu/Debian, it's
inexcusable that old binaries will not run on the same distro's latest
release on the same arch.
This the main reason why Linux can't break into the mainstream desktop apps.
For Debian 11, fixing quickplot will likely involve simply comparing
libsndfile-1.0.28 with Debian's 1.0.31 to identify the "breaking change"
and modifying either quickplot or sndfile to fix the problem.
I'll send you a patch to quickplot in the coming weeks if I end up
changing it, leaving you to wrestle with the GTK3 issues unique to
Debian 12.

P.S. Are you aware of any other graphing package that accepts ASCII
numeric input from a pipe?
(i.e. a viable alternative to quickplot?)

Hi Brent,
5. I forgot to mention. I'm using Debian 12 with GNOME and on that,
both libsndfile and GTK3 break quickplot; though "apt install
quickplot" works, but it installs a broken program. I can't test your
fix very easily on my system. I'd rather refactor quickplot than
downgrade my OS. (ya, I know, VMs, but I worry about slow displays and
lots of unknowns ...; and VMs turn me off in general) GTK3 uses a
Wayland Display (on Debain 12 GNOME) and the X11/wayland wrapper stuff
seems to be broken. You see, quickplot uses raw libX11 code to get
more speed than that is gotten from the cairo/x11 wrapper crap in GDK
(GTK3), on older systems. My refactoring will use WaylandDisplay and
not libX11, and that promises to be much faster than libX11 ever was.
Wayland should be better and faster, but it has been a long time
coming; and has totally broken lots of my code. GdkWaylandDisplay
(GTK3 sub-library) is now giving me pain... I feel that the GTK3 and
GTK4 developers are sadists.
Linus is talking about my pain in this video:

Thanks again for your help. Very helpful feedback.
cheers

Hi Brent,
1. First thank you for submitting this bug ticket. I'm not sure
if I have write access to the debian bug system, but we'll see.
2. I'm the sole downstream developer of quickplot. quickplot as
distributed by Debian GNU/Linux was pretty cool stuff. It
currently has some package dependencies that have broken it. In
particular, libsndfile and GTK3. And so, quickplot is in need of
refactoring, maybe dropping the libsndfile dependency and removing
deprecated GTK3 API usage. As it turns out, I just happened to
have released (alpha) a much larger software package that kind-of
needs a "quickplot" like tool to help my current work. So I need
to fix quickplot for my own use. I have not used it in a while.
3. I looked at your bio. We seem to have a little bit of overlap
in professional interests, my CV is at
http://107.191.96.171/cv.html , sorry it's http without https yet.
4. My new alpha software package is at
https://github.com/lanceman2/quickstream , you might find it
interesting.
cheers
