Can't get it working

[seantalts]

I'm using Dune with this project: https://github.com/stan-dev/stanc3. Dune will build a bytecode or executable file in _build/default/. Here's my launch config:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "OCaml",
            "type": "ocaml-debugger",
            "request": "launch",
            "program": "${workspaceRoot}/_build/default/stanc.exe",
            "console": "internalConsole",
            "stopOnEntry": true,
            "arguments": ["test/integration/examples-good/declarations.stan"]
        }
    ]
}

With the stanc.exe option, it just hangs forever. If I change it to stanc.bc, it does something for a second and then flashes red at the bottom. No errors I can find anywhere.

I just get it working! With this configuration:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "OCaml",
            "type": "ocaml-debugger",
            "request": "launch",
            "program": "${workspaceRoot}/_build/default/stanc.bc",
            "dotMerlins": ["${workspaceRoot}/.merlin", "${workspaceRoot}/lib/.merlin"],
            "arguments": ["${workspaceRoot}/test/integration/examples-good/declarations.stan"],
            "console": "internalConsole",
            "stopOnEntry": false
        }
    ]
}

I'm still getting the same thing where it flashes red for a second and then nothing... I do have this in the "Extensions Output":

Fatal error: exception Not_found

My dune dev profile is:

 (dev
  (flags (:standard -g)))

Perhaps that's not enough?

Thanks for your help!

I use earlybird 0.1.4 and ocaml 4.06.1

I didn't change your build file. But only run dune build stanc.bc.
