FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

addr2line - convert addresses into file names and line numbers.



        addr2line - convert addresses into file names and line numbers.


        addr2line [-b bfdname│--target=bfdname]
                  [-e filename│--exe=filename]
                  [-f│--functions] [-s│--basename]
                  [-H│--help] [-V│--version]
                  [addr addr ...]


        addr2line  translates  program  addresses into file names and line num‐
        bers.  Given an address and an executable, it uses the debugging infor‐
        mation  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
        the file 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, addr2line may be used in a pipe to con‐
        vert 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  FUNC     
        TIONNAME 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
        -b bfdname
            Specify  that  the  object-code format for the object files is bfd‐
            Decode (demangle) low-level symbol  names  into  user-level  names.
            Besides  removing  any  initial underscore prepended by the system,
            this makes C++ function names readable.  Different  compilers  have
            different  mangling  styles. The optional demangling style argument
            can be used to choose an appropriate demangling style for your com‐
        -e filename
            Specify  the  name  of the executable for which addresses should be
            translated.  The default file is a.out.
            Display function names as well as file and line number information.
            Display only the base of each file name.
        Info entries for binutils.

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
