Re: using bfd, help please I am confused

Ian,

Thanks for the help. I do want to get the information from within the
code, thus I do not want to call addr2line. I have this working if I
have a monolithic executable, but how do I get this to work with shared
libraries?

At this point I am assuming that I only know the name of the executable,
since I don't know whether or not there is a way to figure out the
library name from which the function that is currently on the stack came
from.

Thanks,
Robert
