💅 LLVM-INSTALL-NAME-TOOL — the gen z breakdown

okay so bestie, this is llvm-install-name-tool(1), part of the LLVM fam ✨ — and it's literally the tool you want when you need to mess with the install names and rpaths chillin' inside a Mach-O binary. 🦋

🌸 SYNOPSIS 🌸

llvm-install-name-tool [options] input

🎀 DESCRIPTION 🎀

So llvm-install-name-tool is the tool that manipulates dynamic shared library install names and the rpaths listed inside a Mach-O binary. It's giving surgical precision, no cap 💅

And for most scenarios? It works as a drop-in replacement for Apple's install_name_tool. Iconic behavior honestly, we ate. 👑

✨ OPTIONS ✨

Okay so vibe check first: at least one of the options below is required, and some of them can be combined with other options. But lowkey there's a rule — -add_rpath, -delete_rpath, and -rpath can be combined in one invocation only if they don't share the same <rpath> value. fr fr, that's the boundary. 🫶

  • -add_rpath <rpath> — Adds an rpath named <rpath> to the binary you specified. You can throw this flag multiple times to add multiple rpaths. It throws an error if <rpath> is already listed in the binary (no duplicates allowed bestie 💀).
  • -change <old_install_name> <new_install_name> — Changes an install name from <old_install_name> to <new_install_name> in the specified binary. Can be specified multiple times to change multiple dependent shared library install names. This option is ignored if <old_install_name> isn't listed in the binary — like, it just shrugs and moves on 🙈.
  • -delete_rpath <rpath> — Deletes an rpath named <rpath> from the specified binary. Can be specified multiple times to delete multiple rpaths. Throws an error if <rpath> isn't listed in the binary 😭
  • -delete_all_rpaths — Deletes all rpaths from the binary. Clean slate energy, periodt 🌈
  • --help, -h — Prints a summary of the command line options. Your lil cheat sheet 🎀
  • -id <name> — Changes the shared library's identification name under LC_ID_DYLIB to <name> in the specified binary. If you specify it multiple times, only the last -id option is selected (last one wins, main character energy 👑). This option is ignored if the specified Mach-O binary isn't a dynamic shared library.
  • -o <file>, --output <file> — Writes the modified binary to <file> instead of updating the input file in place. Non-destructive queen behavior 💖
  • -rpath <old_rpath> <new_rpath> — Changes an rpath named <old_rpath> to <new_rpath> in the specified binary. Can be specified multiple times to change multiple rpaths. Throws an error if <old_rpath> isn't listed in the binary or <new_rpath> is already listed in the binary ✨
  • --version, -V — Displays the version of the llvm-install-name-tool executable. Slay, know your build 🦋

💀 EXIT STATUS 💀

llvm-install-name-tool exits with a non-zero exit code if there's an error. Otherwise? It exits with code 0. Simple as that, no drama 🍓
