OK, I solved it by myself, Maybe useful to others:
add some config to settings.json:

"cmake.debugConfig": {
        "stopAtEntry": false,
        "MIMode": "lldb",
        "miDebuggerPath": "/Users/xuweiquan/.vscode/extensions/ms-vscode.cpptools-0.20.1/debugAdapters/lldb/bin/lldb-mi",
        "logging": {
                "trace": true,
                "engineLogging": true,
                "traceResponse": true
        }
    }

@shinsei90 can you post your launch.json ?
It seems like you have MIMode set to gdb instead of lldb and you are pointing to the wrong debugger executable. For lldb we use the executable lldb-mi which allows us to drive the debugger through protocol messages.

Also, we default to using our included lldb when miDebuggerPath is not specified. The version of lldb we include specifically works with our extension and includes fixes to support it.

of course here is my launch.json:

shinsei90 picture shinsei90 on 29 Aug 2018

@shinsei90 That's the launch.json you are using when you got that error message? Our default is to use our version of lldb which is not under /usr/bin/lldb.

pieandcakes picture pieandcakes on 29 Aug 2018

Yes, that was the launch.json I used when I got the error message.

shinsei90 picture shinsei90 on 30 Aug 2018

@pieandcakes and?? He said he wants to use custom lldb, not the default

MuhsinFatih picture MuhsinFatih on 10 Oct 2018

@MuhsinFatih by default it should be using our lldb located in ~/.vscode/extensions/ms-vscode.cpptools-0.19.0/debugAdapters/lldb/ which is not what the error is saying.

You can also set miDebuggerPath to point to lldb-mi that is in that folder manually. I've tried using the latest on my Mac and I can't reproduce what you are running into with that launch.json configuration.

pieandcakes picture pieandcakes on 10 Oct 2018

how to solve it ? @pieandcakes

  • OS and Version: Mac OS X 10.12
  • VS Code Version: 1.29
  • C/C++ Extension Version: 0.20
  • CMAKE Tools

Unable to start debugging. Unable to establish a connection to LLDB. The following message was written to stderr:

lldb: unrecognized option `--interpreter=mi'
error: unknown or ambiguous option

the launch.json is generated by default

joole picture joole on 15 Nov 2018

@joole can you confirm that you have lldb-mi executable in your extensions folder? Are you specifying your own miDebuggerPath? If so, you need lldb-mi and not lldb.

pieandcakes picture pieandcakes on 15 Nov 2018
👍1

@pieandcakes yes,the path "~/.vscode/extensions/ms-vscode.cpptools-0.20.0/debugAdapters/lldb/bin/lldb-mi" has one, the other one in the xcode install path, even if i set the value of miDebuggerPath , that's the same error

joole picture joole on 15 Nov 2018

@joole If you are setting miDebuggerPath you need to find lldb-mi and not lldb as we use mi mode to send and receive commands from lldb. If you want to use the xcode version, you will need to figure out where that is.

@pieandcakes
here is the launch.json

but error as before~

@pieandcakes
I watch the log of output, find when debug the program the debugger alway the /usr/bin/lldb,even if the set the value of miDebuggerPath, how to fix it ? please help me

Can you turn on traceResponse logging and share the output?

pieandcakes picture pieandcakes on 15 Nov 2018

@pieandcakes
only this message 

Starting:` "/usr/bin/lldb" --interpreter=mi
lldb: unrecognized option `--interpreter=mi'
error: unknown or ambiguous option

anything useful information or log generated when add the logging to the launch.json

by the way, I use the cmake-tools to config the cpp

joole picture joole on 15 Nov 2018

I can't duplicate this on my current Mac. Which version of xcode do you have installed? I'll see if I can get an updated Mac and try this.

pieandcakes picture pieandcakes on 15 Nov 2018

@pieandcakes
xcode3 on mac mini and xcode9 on mac pro,as I think, you can get the same result with the following step:

  1. install vscode with plugin cpp-tool cmake-tool python-tool and cmake
  2. in the terminal, using cmake to generate project
  3. use vscode open the folder then let the vscode generate anything
  4. on vscode statusbar, click the debug icon then can happen it.

@joole Thanks. Its interesting that the CMake extension is overwriting our debug path.....

pieandcakes picture pieandcakes on 16 Nov 2018

@joole So I found the difference. If you use the CMake pane in VS Code and choose Run with debugger , then it won't work until you add that block.

I have filed an issue with them as this is the CMake Tools extension that is sending us bad information. If you want to use what is in your launch.json, then you need to use the Debug pane and use the Start Debugging button or by pressing F5.

I imagine that this is @shinsei90 's issue also.

pieandcakes picture pieandcakes on 16 Nov 2018

To clarify for anyone watching: Using the Run with debugger command, the "Debug" button in the status bar, and running the "CMake: Debug Target" command will generate a debugger configuration on-the-fly for the target you've selected, it won't consult the launch.json at all. Here are my docs on debugging, and particularly the section on using launch.json for debugging.

@vector-of-bool Thanks for the information!

pieandcakes picture pieandcakes on 26 Nov 2018

OK, I solved it by myself, Maybe useful to others:
add some config to settings.json:

"cmake.debugConfig": {
        "stopAtEntry": false,
        "MIMode": "lldb",
        "miDebuggerPath": "/Users/xuweiquan/.vscode/extensions/ms-vscode.cpptools-0.20.1/debugAdapters/lldb/bin/lldb-mi",
        "logging": {
                "trace": true,
                "engineLogging": true,
                "traceResponse": true
        }
    }

This solution does not work for me.
As an alternative solution, I build the project using the tool. And use this launch.js config to run the project via top debug button.

    "configurations": [
        {
            "name": "(lldb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build/excuteable",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "lldb"
        }
    ]

@czyang That block uses our extension to kick off debugging whereas the above block you quoted is from @vector-of-bool 's CMake Tools Extension. If you can provide him more information, he might appreciate knowing what the cause is.

@zhusjfaker Please reference pinned issue #3829. Yours is not this issue.

pieandcakes picture pieandcakes on 11 Nov 2019

Type: Debugger
lldb-902.0.79.7
Apple LLVM version 9.1.0 (clang-902.0.39.2)

Describe the bug

  • OS and Version: Mac OS X 10.13.6
  • VS Code Version: 1.26.1
  • C/C++ Extension Version: 0.18.1
  • CMAKE Tools
  • I got the following message on a pop up windows:

Unable to start debugging. Unable to establish a connection to LLDB. The following message was written to stderr:

lldb: unrecognized option `--interpreter=mi'
error: unknown or ambiguous option

  • and I got this error message on the debug console:
Starting:` "/usr/bin/lldb" --interpreter=mi
lldb: unrecognized option `--interpreter=mi'
error: unknown or ambiguous option

You shouldn't be targeting lldb but rather lldb-mi. For lldb we require the lldb-mi executable as it contains the mi instructions we need to communicate with the debugger.

pieandcakes picture pieandcakes on 13 Feb 2020

When I run lldb-mi executable from the terminal, it loads gdb. Any reason for that?

sukuya picture sukuya on 28 Feb 2020

@sukuya It shouldn't unless you have it mapped. I know it "emulates" gdb's MI mode so it will say (gdb) as that was what is expected by all the tools out there when a debugger is running in mi mode. If you are saying that it is actually gdb then there might be a symlink somewhere.

pieandcakes picture pieandcakes on 28 Feb 2020

It just says gdb. Thanks @pieandcakes for the clarification.
