I don't know, but I just hate you.

kidding, I truly have you in high regard for your kind rework of pov's 
radiosity. ;)

Don't be so impatient.  Any more tip, just call...

You didn't get my point: I'm more into hypertext online helps in a dedicated
window, not something that goes on in a standard terminal window.

Well, maybe Linux people can't understand why anybody would have such
preferences, but... well, there *is* something intuitive about having different
things look different on the desktop...

And here you got it again what my whole lamenting is about: Finding out how to
get line numbers out of a core dump or valgrind run seems to boil down to a
detective's job, and I don't have the time nor patience to do it.

You're welcome - as long as you're not saying that I'm crap :P

Yeah - just tell me what freakin' compiler settings *should* get me those
freakin' line numbers in those freakin' coredumps, and I might freakin' get
ahead somehow to find out how to ./configure POV for that... as of now, nobody
seems to know those Linux compilers well enough to boldly make a statement that
options X and Y will give me what I want. All people come up with is "go look
for yourself, it's sooooooo easy..."

Hey, come on guys, here's something where YOU can help make POV radiosity
better: Invest a few minutes to help a Windows-spoilt developer along on a
Linux machine...

...... oh, by the way: Settings for Intel compiler preferred. To my experience it
does a better job at optimization, so that's the one I'm normally using for
POV. Though I (generally) know how to ./configure POV to compile with gcc, too.


So anyone want those sporadic crashes of Linux POV gotten rid of before they
wind up in some beta? Here's the deal: Somebody help me with that, and I'll give
it a try. Or nobody helps me, and I'll leave that job to someone else more
familiar with Linux development. Both fine with me, though I'd prefer to know
that the betas will be "clean" in this respect.

No, I understand perfectly.  For a dedicated window, you can always open 
up an extra terminal window as well - there are options.  Or if you 
really want to look at the help in an editor/web page/whatever, open the 
configure script up in that and go to the part of the page that shows the 
help.

What you're lamenting about is that Linux isn't Windows.  Surprise! ;-)

Well, it's not the sort of thing I do on a daily basis, so if I have to 
google it, then it makes sense to say "the info's out there".  We've been 
down this road before.  Like Nem said, I appreciate the work you're doing 
on the radiosity code and think it's great...

So to help out, I've done the googling.

-g enables line numbers (not as a parameter to the configure script, as a 
parameter to the gcc compiler).  I've just confirmed this with a simple 
"hello world" program:

main () at hello.c:6
6		puts("Hello World");
(gdb) 

This break point is at line 6.

I have no idea about Intel's compiler; don't have it installed, never 
used it before.

Are you loading up a core file from a crash in gdb?  Or are you 
duplicating the crash by running povray under gdb?

Sorry, I didn't turned on my PC last night, but I'll try to core dump 
something today once I get home, in about 7 hours.  I'll help you, 
spoiled Windows child.  :)
