I cannot use gdb since I am writing a script who needs to reverse map. 
With addr2line both with:

addr2line -e libname address

and 

addr2line -e executable address

all I get is 

??:0

ie cannot determine file, cannot determine line number.

Also I have run strings on my -g built library and I don't see any
mention of file name.  How does addr2line get that info?  I didn't
see any mention of a parm relative to where the source is.  Do I have
to be in the directory containing the source?
