Hi,
I'm trying to use my own histogram division function and the errors keep
coming out as 1.0. That's using Linux version 3.05/06 of ROOT, and
ACLiC-compiled code. When in trace mode, interpreted mode, I'm getting
the most interesting crash, which I include below (no crash when
compiled, only error=1.0 for every histo bin).
I have taken steps to ensure there were no invisible or special
characters in my code: I did a "cat" of my file to the screen and
copy-pasted it into a fresh emacs window for that file. I also simply
deleted the line and retyped it.
Note below that "cerr <<" of my variables shows valid numbers. Line 37
is *supposed* to read:
(cc!=0.0 && bc!=0.0) ? a->SetBinError(i,err) :
a->SetBinError(i,0.0);
...yet ROOT seems not to think I have a valid expression. Any advice?
I hope I'm just doing something dumb...but I can't spot it!
