i tried beta 2
i tried it with
#!/bin/bash
CXXFLAGS="-std=c++11"
../configure -q COMPILED_BY="RSM"
make clean
make
make check
make install
the output when rendering biscuits.pov is entirely black
the output when rendering the test scene bill provided is green

Hi,
Unsure about the web site issue. I mostly use thunderbird. Going to to
web site forum interface just now (using firefox), I see in the unix
newsgroup 13 totals posts in this thread - which matches what I see via
thunderbird though as a couple branches from your original post. So,
things look OK to me.
Aside: Posts on a topic end up presented as a single sequence on the web
site interface no matter the newsgroup's hierarchy for the topic.

That you see green with the sphere scene test is fair confirmation
whatever is happening is related to bounding(a).
POV-Ray ships with two bounding methods (1 & 2). What happens if you
switch to bounding method two using the flag +bm2 ?

(a) - I have not even a guess as to cause...

wow. completely outside my experience..
just to confirm, the archive(s) you used came from
<https://github.com/POV-Ray/povray/tags/> ?

Awoke with a few additional thoughts in my head.
1) That +bm2 is a run time, command line flag passed to povray.
2) You could also try the run time flag, -mb, which in v3.7/v3.8
official versions of POV-Ray turns off most bounding - but not all of it
as happens in v3.6 and prior. The renders would be slow, but if they
aren't blank, this would tell us something I guess.
3) You could try my 'povr' fork of POV-Ray... You can find the latest
source build tarball at:
http://news.povray.org/povray.binaries.programming/thread/%3C64f34751%40news.povray.org%3E/
My version of POV-Ray does NOT yet have the OpenEXR 3.1 patches needed
to compile and use that library - because I'm not immediately set up to
test them.
It does have many updates related to the build process and the source
code.
Take care to not do a 'make install' with it, but rather the test would be:
./configure -q COMPILED_BY="RSM_noEXR" --without-openexr
make -j4
make check
4) It sank in that while the fedora version you have is old, most
everything else you are using with respect to compiler and libraries is
recent. Maybe something in all that. I'd make a small bet on boost being
the culprit, if so.

thank you for the link to your version of povray bill.

this is fedora 38 not 3.8
fedora 38 was released in april of 2023
as you said it could be a library related issue. many of the libraries are newer
thank you for your suggestions

i found sdl12-compat and installed it
then i recompiled it
checking for libSDL... yes
checking for libSDL version >= 1.2... 1.2.68, ok
checking for SDL/SDL.h... yes
checking for SDL_Quit in -lSDL... yes
X Window display: enabled (using SDL)
when it got to the make check a little window popped up and
the display inside was all black.
when i rendered the sphere that bill suggested as a test i got a green image
when i tried rendering my scenes i got a white image and it rendered very fast.
when i rendered the biscuit.pov i got a black image.

Ah... My old mind glitching. Something it does all too often these days.

Dropping in the discussion;
You might want to compare official code with hg-povray code for display
( https://github.com/LeForgeron/povray/tree/hgpovray38/unix )
as I made a port for libsdl2 and raw X11 (but you cannot compile for
both libsdl 1.2 and libsdl 2.0, they are using the same API with
different interfaces (they fucked it))
IIRC, libdsl2 is far better that 1.2
