The GNU Binary Utilities, or binutils, is a collection of programming tools maintained by the GNU Project for working with executable code including assembly, linking and many other development operations.
The tools are originally from Cygnus Solutions.
The tools are typically used along with other GNU tools such as GNU Compiler Collection, and the GNU Debugger.
Tools
- As of 26 July 2026[2] the tools include:
addr2line | convert address to file and line |
ar | create, modify, and extract from archives |
as | assembler popularly known as GAS (GNU Assembler) |
c++filt | demangling filter for C++ symbols |
dlltool | creation of Windows dynamic-link libraries |
elfedit | allows alteration of ELF format files |
gold | alternative linker for ELF files |
gprof | profiler |
gprofng | collects and displays application performance data |
ld | linker |
nlmconv | object file conversion to a NetWare Loadable Module |
nm | list symbols exported by object files |
objcopy | copy object files, possibly making changes |
objdump | dump information about object files |
ranlib | generate indices for archives (for compatibility; same as ar -s) |
readelf | display contents of ELF files |
size | list section sizes and total size of binary files |
strings | list printable strings |
strip | remove symbols from object files |
windmc | generates Windows message resources |
windres | compiler for Windows resource files |
elfutils
Ulrich Drepper wrote elfutils, to partially replace GNU Binutils, purely for Linux and with support only for ELF and DWARF. It distributes three libraries with it for programmatic access.[3][4]
