LLDB vs GDB notes — authorized decision checklist

Snapshot

Decision checklist (authorized only)

1. What does the course image already ship? Prefer that debugger first.
2. Is the target an Apple platform build? Start LLDB unless the syllabus says otherwise.
3. Do you need GEF/PEDA/pwndbg-style workflows? Bias toward GDB + approved plugins.
4. Do you need LLDB Python scripting on LLVM toolchains? See LLDB Python.
5. Record lldb --version / gdb --version in the case binder for every session.
6. Never pick a debugger to bypass protections on software you may not analyze.

Allowed framing

• Picking a default for a new authorized native-lab VM.
• Explaining to students why macOS demos use LLDB while a Linux CTF box uses GDB+GEF.
• Keeping Evidence labeled with the debugger that produced it.
• Switching tools mid-course when the syllabus migrates — with version notes.

Scope we will not cover

• No "undetectable debugger" or anti-anti-debug recipes.
• No crack/keygen workflows on either debugger.
• No exploit PoCs that require a specific debugger UI.
• No unauthorized attach to third-party production processes.

Beginner path (authorized only)

1. Read the LLDB-first or GDB-first compare that matches your host.
2. Run hello under the chosen debugger on an authorized binary; save a backtrace.
3. Repeat once on the other debugger if both are installed — note command differences.
4. Pick one default for the week; document why.
5. Escalate scripting via LLDB Python or GEF tips as needed.
