addr2line - convert addresses into file names and line
[-b bfdname | --target=bfdname] [-C|--demangle]
[-e filename | --exe=filename] [-f|--functions]
[-s|--basenames] [-H|--help] [-V|--version]
addr2line translates program addresses into file names and
line numbers. Given an address and an executable, it uses
the debugging information in the executable to figure out
which file name and line number are associated with a given
The executable to use is specified with the -e option.
The default is a.out.
addr2line has two modes of operation.
In the first, hexadecimal addresses are specified on the
command line, and addr2line displays the file name and
line number for each address.
In the second, addr2line reads hexadecimal addresses from
standard input, and prints the file name and line number
for each address on standard output. In this mode, ad-
dr2line may be used in a pipe to convert dynamically chosen
The format of the output is FILENAME:LINENO. The file
name and line number for each address is printed on a separate
line. If the -f option is used, then each FILENAME:LINENO
line is preceded by a FUNCTIONNAME line which
is the name of the function containing the address.
If the file name or function name can not be determined,
addr2line will print two question marks in their place.
If the line number can not be determined, addr2line will
Specify the object-code format for the object files
