The obvious question now is : what scene are you trying to render?

../configure -q COMPILED_BY="RSM"
make clean
make
make check

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 ?

Bill P.

(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.
