Debugging

• OCaml comes with a built-in debugger for the bytecode compiler. You invoke it with the ocamldebug command. See the manual for more details.
• The easiest way to debug OCaml code, other than inserting print statements, is choosing bytecode as your compilation target, and using teh OCaml debugger.
• Additionally, one can use gdb to debug native code.
• ocamlearlybird: Debug Adapter Protocol implementation for OCaml. Allows integrating the OCaml debugger with an IDE.
• ocaml-dap: Generic Debug Adapter Protocol implementation in OCaml.
