Debugging with lldb-vscode on windows raises an exception and displays disassembly #307
Comments

This is what the bug looks like in action: |
|
does not look like a dap issue im not on windows but i'd try to overwrite the |
|
Tried hardcoding all the paths to no avail. I've simplified the issue to some python/extension related crash on lldb-vscode by creating an empty rust project and running |
|
I can confirm when resolving the python issues, it reverts back to raising an exception and dumping out the assembly. |

I can also reliably reproduce this with a hello world program written in C. Here is the dap log: |
|
CodeLLDB is also using the debug adapter protocol, so it should be possible to get it working with nvim-dap as well. (I guess the issues encountered here are part of the reason why vimspector recommends CodeLLDB) |
Yes, after looking at the source code structure, I found CodeLLDB using dap with its own rust implementation, there may be some way to get it to work with I think building |
Is there a source for this? The reason why I ask is I have already tried building lldb-vscode using Visual Studio/MSVC toolchain with the exact same result. Unless there is some LLDB compile flag I am missing that specifically enables MSVC toolchain debugging and I cannot find any mention of it. |

I've managed to get CodeLLDB to work with
local lldb_host = "127.0.0.1"
local lldb_port = 34567
dap.configurations.rust = {
{
name = "Debug",
type = "lldb",
request = "launch",
host = lldb_host,
port = lldb_port,
program = function()
return vim.fn.input("Path to executable: ", vim.fn.getcwd() .. "/", "file")
end,
cwd = "${workspaceFolder}",
stopOnEntry = false,
args = {},
},
}
dap.adapters.lldb = function(callback, config)
callback({ type = "server", host = config.host, port = config.port })
endOpen /path/to/codelldb.exe --liblldb /path/to/liblldb.dll --port 34567You can write some trivial functions to make it start automatically when executing Some screenshots: C: Rust: |

This CodeLLDB configuration I can confirm works just fine in windows. Thanks! |
|
can we close this ? |

Sorry to further use this thread, but i found some (marginally) related info. Showing disassembly is intended by CodeLLDB (here). Normally this option would be set by the various configuration files in Visual Studio Code. One can however pass parameters to the ./codelldb --params '{"showDisassembly" : "never"}They are concatenated with the other options, so my guess is that they override previous set options, but I did not test this. BTW, there is also the option of PS: |
|
Sounds like the issue is resolved? I created a wiki page for codelldb: https://github.com/mfussenegger/nvim-dap/wiki/C-C---Rust-(via--codelldb) |
I got this error with the configurations posted on wiki:

I edited the Wiki page. Please have a read through it. Also, there is a similar issue on the |
