【debugger startup problems】codelldb: Syntax error: word unexpected (expecting ")")

[ctaoist]

OS: Linux 4.15.0 VSCode version: 1.45.1 code server version: 3.3.1 Extension version: 1.5.0

Problem: When start a debugger for rust bin, the vsocde outputs:

Running `cargo build --bin=hello --package=hello --message-format=json`...
    Finished dev [unoptimized + debuginfo] target(s) in 0.06s

Error: The debugger exited without completing startup handshake.

This looks as if a shell was invoked to execute the codelldb binary.
Since you mentioned code server, I assume you are using VSCode remoting? What OS and CPU architecture is the remote machine?

@vadimcn code server: https://github.com/cdr/code-server My code-server is installed by cdr's docker image.

And I cd to ~/.local/share/code-server/extensions/vadimcn.vscode-lldb-1.5.0/adapter and execute the codelldb binary manually, then bash shell outputs:

bash: ./codelldb: cannot execute binary file: Exec format error

I'm seeing this issue too (as well as the cannot execute binary etc.), both on 1.5.0 and 1.5.2. Also on code-server.

[vadimcn]

I've reproduced this with the docker image. Looks like they cached the wrong version of the extension package - the arm64 one.
I recommend that you download the package from MS Marketplace and "Install from VSIX".

That worked for me! Thanks!

[ctaoist]

That works well! Thanks extremely!
