rust-gdb and rust-lldb not working using stable-x86_64-pc-windows-gnu toolchain

Problem

expected debugget output but this message pops up
the 'rust-gdb.exe' binary, normally provided by the 'rustc' component, is not applicable to the 'stable-x86_64-pc-windows-gnu' toolchain

Steps

1.type rustup-gdb or rustup-lldb

Possible Solution(s)

Notes
Operating system:Windows 10 pro version 10.0.19042 Build 19042
Using mingw-64
Output of rustup --version: rustup 1.24.3 (ce5817a 2021-05-31)
Output of rustup show:
Default host: x86_64-pc-windows-gnu
stable-x86_64-pc-windows-gnu (default)
rustc 1.54.0 (a178d0322 2021-07-26)

I think (maybe) the issue is that rustup is assuming all executables end with .exe here, but scripts like rust-gdb are shell scripts which do not have the extension.

Certainly on Windows we blindly append the extension .exe -- perhaps

we should use PATHEXT rather than always assuming .exe
we should consider how to have rust-gdb and rust-lldb scripts which will work on native Windows and then give the new scripts appropriate extensions.

Failing that, I suppose we could detect the missing executable, but the fact that the component is already installed and present a better error message.

Same issue ...

D:\RustTest01>rust-lldb
error: the 'rust-lldb.exe' binary, normally provided by the 'rustc' component, is not applicable to the 'stable-x86_64-pc-windows-msvc' toolchain

D:\RustTest01>which rust-lldb
/d/Programs/Rust/.cargo/bin/rust-lldb

Based on the link, I am able to debug rust in windows with rust-gdb in Visual Studio Code using the below configuration,

{
            "type": "gdb",
            "request": "launch",
            "name": "Debug Launch",
            "target": "${workspaceRoot}/target/debug/${workspaceRootFolderName}.exe",
            "cwd": "${workspaceRoot}",
            "valuesFormatting": "parseText",
            "gdbpath": "C:/Users/selva/.cargo/bin/rust-gdb.cmd",
            "preLaunchTask": "cargo build (stable-gnu)",
        }

But the pretty printer is not working. It is showing address instead of string.

Has there been any progress on this?

I will try to fix it.

I will try to fix it.

@hi-rustin Is there any progress on this issue? The rust-lldb is perfectly runnable in MSYS2 as long as the LLDB is installed. Technically it may be fixed by figuring out 1) how to distribute the LLDB, and 2) how to distribute an MSYS2-like run environment, or create an equivalent cmd script. Is there any particular problem that blocks this naive solution?

@luowyang Sorry, but @hi-rustin is not on the team currently... Maybe we need to find some time to pick up the lost context...

error: the 'rust-lldb.exe' binary, normally provided by the 'rustc' component, is not applicable to the 'stable-x86_64-pc-windows-msvc' toolchain

For the short term workaround, I think it might be better to just not proxy these on Windows hosts. It's better there be no proxy than broken ones. When an actual fix is created they can be added back.
