Hey, I’m currently trying to debug a very simple OCaml program via lldb on MacOS. The program let printSum sum = Printf.printf "Sum: %d\n" sum let () = let x = 1 in let y = 2 in printSum (x + y) I was following Getting Started with LLDB on OCaml · Perpetually Curious Blog and bu…

No you are not doing anything wrong, that is the state of debugging with LLDB on MacOS. So #13050 will restore setting breakpoints using the current name mangling scheme in 5.2 and will work nicely with tab complete in LLDB. It’s marked for 5.3 release so fingers crossed it makes it.

Awesome, thanks for the explanation! I was trying for hours with multiple local switches and different setups :person_facepalming: back to ocamldebug it is then (at least for the time being).

[image] lambda_foo: It’s marked for 5.3 release so fingers crossed it makes it. I fear that this feature was not ready in time for the 5.3 feature freeze in August. It will not be part of the 5.3 release.

[image] lambda_foo: I’m actively working on a fix for this issue. @lambda_foo do you have an idea when your work on Mach-O binaries will be ready/merged?

Over the next few months I expect to have an implementation for writing minimal DWARF such that setting breakpoints based on filename and line number works on macOS. Either that or #13050 will give a decent experience setting breakpoints. Aiming for both to be available in 5.4.

What about source code not being available? Is this the same issue? Also, how can I contribute to fixing it?
