Hi Tracers!
Recently, I updated my Linux system from RedHat 6.1 to RedHat 6.2. Since
then, I can't use the +c command line option anymore! However far I
rendered at the moment of aborting, when I try to resume the rendering,
PoV-Ray starts all over again, but, strangely, displays one line less to
render than the rendering's original length... is this a PoV-Ray or a
RedHat bug?
See you in Khyberspace!

Well, a bit more information is necessary :-)
Which version of POV-Ray are you using?
What are the exact command line settings?
What is the image format you are using?
Do you have permissions to write to the output directory?

Yes, normally, I log in as root (please don't stone me for this
foolishness...)

>PNG.
Is it possible that your new OS came with a newer version of libpng.so
that is almost, but not quite, entirely unlike the version POV was linked
against? Have you tried rebuilding POV?

No, I haven't... and a have not even a notion about how I should do that - finding
the new libpng somewhere deep in the innards of Linux (excuse me, but I'm quite a
Linux newbie!) and then hacking the PoV source code?
Meanwhile, I contented myself with switching to compressed TGA when rendering...
but of course, I'm curious about fixing the PNG problem!
See you in Khyberspace!

There shouldn't be any hacking necessary; you should be able to get away with
just building the code that's available. Assistance on doing that might be
easier to find in the povray.unix group, so I'm redirecting followups there.
