----------
make check did not show the biscuit
i ran the build as root
the make report is attached.
the output was very quick and still resulted in a png file that was totally
white.
when i run this on windows version of povray it works. however i am having other
problems with the windows version where it will try to parse a scene and crashes
with a memory permissions error with some scenes.

i tried to attach the report to this thread but it would not work
please see the message here:
http://news.povray.org/web.6519a52bfee355a638789ea2e542b12d%40news.povray.org
it did not show the biscuit image when i ran the make check
i was logged in as root when i compiled the program
when i ran a render after the compile finished as a png file
the output was totally white again
i was able to run this on the windows version of povray but i am having issues
with it as well.
on some scenes the render crashed and i get a memory exception error.

fwiw (and it should not make a difference), 'root' ought not be needed except
for 'make install'.

cannot say anything about MS Windows version, but ime self-compiled POV-Ray is
solid and dependable[*]. I've looked through the build log (thanks) but
everything looks .. nominal. I'm guessing that o/wise you have no problems with
any of the linked-to libraries ? the only "straw to clutch" I can think of is
that your compiler may be too new ? try with '-std=c++11' in the CXXFLAGS.
right out of ideas, otherwise. sorry.
[*] there are known bugs, of course.
regards, jr.

Certainly odd.
The output from make check shows that all the ray -> bounding tests
failed. If you code up:
//--- test.pov
sphere { 0, 5000
hollow
pigment { rgb <0,1,0> }
finish { emission 1 }
}
//---
and run it by pointing directly to the <build dir>/unix/povray executable:
<build dir>/unix/povray test.pov
Do you see a green render? (You'll need to do this as root (or via sudo)
as you compiled as root)
Above scene should bypass the bounding and all rays will land on the
inside surface of the sphere.

Aside: It might be worth doing a build as a regular user. It should be
you can do everything but a machine level install. In other words, 'make
check' should run fine.
Aside: You have 16 threads, you can compile faster after configuration
by using:
make -j16
make check

Also...
Is there a reason you are using 'povray 3.8 beta 1' over the newer
'povray 3.8 beta 2'?
Are you building from the linux / unix tarballs from github? Only those
support the traditional immediate ./configure build IIRC.

i am using the povunix-v3.8.0-beta.1.tar.gz tarball from github
i am willing to try 3.8 beta 2
do i need to change my settings to compile as a user instead of root?

I'll take you to mean ./configure settings.
It should be most users can just use:
./configure -q COMPILED_BY="RSM"
make -j16
make check
in the <unpacked tarball directory> as a start.
Maybe you need some of those other configure settings you've previously
used on your machine, but I'd hope configure would sort out most things
for you on a standard fedora install. Your Fedora 3.8 is relatively old
though, so maybe not.
Aside: jr's idea about hard setting the compiler version is worth a try
too - if things continue to be weird, but I'd try a simple ./configure
to start.

Bill
when i rendered the test.pov image the png file was entirely green.
/usr/local/bin/povray test.pov
another wierd thing that i am noticing with the povray website is that when i
visit the unix section of the list. and choose my original message it only shows
two of the messages however when i go to the recent threads page i see all of
the replies.
i tried pointing to the povray binary directly when i rendered a scene and it
produced a white image

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