addr2line [ -b bfdname | --target=bfdname ] [ -C | --demangle ] [ -e filename | --exe=filename ] [ -f | --functions ] [ -s | --basename ] [ -H | --help ] [ -V | --version ] [ addr addr ... ]
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 address.
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,
addr2line displays the file name and line number for each
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,
addr2line may be used
in a pipe to convert dynamically chosen addresses.
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 print 0.
The long and short forms of options, shown here as alternatives, are equivalent.
