addr2line(1) GNU Development Tools addr2line(1)NAMEaddr2line - convert addresses into file names and line numbers
SYNOPSISaddr2line
[-b bfdname | --target=bfdname] [-C|--demangle] [-e filename |
--exe=filename] [-f|--functions] [-s|--basenames] [-H|--help]
[-V|--version] [addraddr...]
DESCRIPTIONaddr2line 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
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 in‐
put, and prints the file name and line number for each address on stan‐
dard 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 op‐
tion is used, then each FILENAME:LINENO line is preceded by a FUNCTION‐
NAME 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.
OPTIONS-b bfdname
--target=bfdname
Specify the object-code format for the object files to be bfd‐
name.
-C
--demangle
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.
-e filename
--exe=filename
Specify the name of the executable for which addresses should be
translated. The default file is a.out.
-f
--functions
Display function names as well as file and line number informa‐
tion.
-s
--basenames
Display only the base of each file name.
