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 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 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.
