rust-analyzer version: rust-analyzer 1.66.1 (90743e7 2023-01-10) rustc version: rustc 1.66.1 (90743e729 2023-01-10)

I installed rust-analyzer via: rustup component add rust-analyzer. And told my IDE to use this: /home/dimanne/.cargo/bin/rustup run stable rust-analyzer -v --log-file /home/dimanne/ra.txt --no-log-buffering.

But it is not working for me...

Attempt 1: Empty initializationOptions

Here is full debug output: https://gist.github.com/DimanNe/66cbc6c0622e655ba94739ea6e4e10d9

Attempt 2: Set `linkedProjects`

I tried specifying linkedProjects in initializationOptions:

{
  "linkedProjects": ["/home/dimanne/devel/raspberrypi/thermo_rust/thermo/Cargo.toml"]
}

I got the following output:

LanguageClient Rust: The command "/home/dimanne/.cargo/bin/rustup run stable rust-analyzer -v --log-file /home/dimanne/ra.txt --no-log-buffering" terminated with exit code 101.
LanguageClient Rust: Unexpectedly finished

It looks like both ends with this:

Any suggestions / ideas?
