Tools for working with ELFs

Here I collect a list of tools which I found useful for working with ELFs (incl. executables and shared libraries).

Dumping symbols

• objdump: objdump --TC xxx.so
  • The -C flag enables demangling.
• ldd: ldd xxx.so
  • Print shared object dependencies, which allows you to find out which shared library is missing.
• ld: ld xxx.so
• nm: nm xxx.so
  • The -C flag enables demangling.
• readelf: readelf --dyn-syms xxx.so
  • The --demangle flag enables demangling.
• patchelf:
  • Particularly useful when you bring your own GLIBC and want to link to the updated one.

Demangling

• llvm-cxxfilt installed with LLVM
• c++filt on Linux
