NAME
addr2line -- translate program addresses to source file names and line numbers
SYNOPSIS
addr2line [-b target | --target=target] [-e pathname | --exe=pathname] [-f | --functions] [-j sectionname | --section=sectionname] [-s | --basename] [-C | --demangle] [-H | --help] [-V | --version] [hexaddress...]
DESCRIPTION
The addr2line utility translates program addresses specified by the command line arguments hexaddress to their corresponding source file names and line numbers. If no arguments are given to addr2line, it will read these addresses from standard input. Program addresses specified by arguments hexaddress are encoded using the conventions accepted by strtoull(3). By default, addr2line will use the executable ``a.out''. The -e option may be used to specified a different ELF object. The addr2line utility recognizes the following options: -b target | --target=target This option is recognized by addr2line but is ignored. It is supported for compatibility with GNU binutils. -e pathname | --exe=pathname Use the ELF object specified by argument pathname to translate addresses. If this option is not specified, addr2line will use the file ``a.out''. -f | --functions Display function names in addition to file and line number information. -j sectionname | --section=sectionname The values specified by arguments hexaddress are to be treated as offsets into the section named sectionname. -s | --basename Display only the base name for each file name. -C | --demangle Demangle C++ names. -H | --help Print a help message. -V | --version Print a version identifier and exit.
OUTPUT FORMAT
If the -f option was not specified, addr2line will print the file name and line number for each address specified on a separate line. If the -f option was specified, addr2line will print a line containing the name of the function corresponding to program address hexaddress, followed by a line with the file name and line number. The addr2line utility prints the file name and line number using the format ``FILENAME:LINENUMBER''. If a file or function name could not be determined, addr2line will print a question mark in their place. If the line number could not be determined, addr2line will print a zero in its place.
EXAMPLES
To map address 080483c4 in the default executable a.out to a source file name and line number use: % addr2line 080483c4 To map address 080483c4 in executable helloworld, use: % addr2line -e helloworld 080483c4 To have addr2line act as a filter reading addresses from its standard input use: % addr2line To print the function name corresponding to an address in addition to its source file and line number use: % addr2line -f 080483c4
EXIT STATUS
The addr2line utility exits 0 on success, and >0 if an error occurs.
