Debugging doesn't start

[muchitto]

I'm trying out the debugger after a short break from using Haxe/Hashlink and it seems to not work anymore. When I try to debug, it builds using the build.hxml file but doesn't start the actual program for debugging. It runs fine if I just run the .hl file from the command line, tho.

My build.hxml:

-cp src 
-m Main

-lib heaps
-lib hlsdl

--hl bin/app.hl

--debug

My src/Main.hx:

class Main extends hxd.App {
    public static function main () {
        new Main();
    }
}

My .vscode/launch.json:

{
    // 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": "HashLink (launch)",
            "request": "launch",
            "type": "hl",
            "cwd": "${workspaceFolder}",
            "preLaunchTask": {
                "type": "haxe",
                "args": "active configuration"
            }
        },
        {
            "name": "HashLink (attach)",
            "request": "attach",
            "port": 6112,
            "type": "hl",
            "cwd": "${workspaceFolder}",
            "preLaunchTask": {
                "type": "haxe",
                "args": "active configuration"
            }
        }
    ]
}

OS is Windows 10, Haxe version 4.2.4, Hashlink is the latest from github and my vscode version is 1.62.3.

Nobody? :)

Try opening the developer console in VSCode – it's like the Chrome console – to see if any errors from the debugger plugin are being thrown

[muchitto]

There was an error after the debugger controls (step over etc) disappear. In the bottom status bar it says "Debugging is Started" and turns to "Debugging is Stopped" and then back to "Debugging is Started" and it disappears after that.

The error says LLDB for VSCode. This is not the Hashlink debugger. Are you sure you run the correct launch config for Hashlink debugging?

[muchitto]

Eh... I had the CodeLLDB extension installed. I uninstalled it and the errors do not appear anymore, but the debugger still doesn't work. Yes I use the launch.json that I posted here.

[hoseyjoe]

It didnt work when I had

{
            "name": "HashLink (launch)",
            "request": "launch",
            "type": "hl",
            "hxml": "hl.hxml",
            "hl": "C:/SDKs/hasklink/hl.exe",
            "program": "${workspaceFolder}/build/heaps/Simplified.hl",
            "cwd": "${workspaceFolder}",
            "preLaunchTask": {
                "type": "haxe",
                "args": "active configuration"
            }
        }

I removed "hxml": "hl.hxml"so I had

{
            "name": "HashLink (launch)",
            "request": "launch",
            "type": "hl",
            "hl": "C:/SDKs/hasklink/hl.exe",
            "program": "${workspaceFolder}/build/heaps/Simplified.hl",
            "cwd": "${workspaceFolder}",
            "preLaunchTask": {
                "type": "haxe",
                "args": "active configuration"
            }
        }

And for the first time in a year I had hl debugging

[alfredbaudisch]

Want to report the same, the Debugger just won't start. There's no output messages either.

• Using both the extension from the Marketplace, then compiled from master next.
• Changed the port in launch.json and also in adapter.js to a high number like 30001.
• No effect in any case. The application is built but nothing else happens.

I have a similar problem on windows 11. I know it worked before. I've tried versions of the debugger and vshaxe from a year ago, and also building the debugger. Sometimes I get a "Failed to connect on debug port" message. Logs do not show anything. I've checked my ports and it looks like nothing starts and listens on 6112. Is it possible that the debugger is not even starting, and the session attempts but fails to connect to it?

Edit: It works on my win11 laptop with the same haxe and hl version, and with extension syncing on vscode. Weird. I'll make sure everything is the same.
