Error following the 'Getting started' tutorial

[Jasperav]

I am on MacOS and I have installed Docker Desktop and cross. I am following this steps that are mentioned here: https://github.com/cross-rs/cross/wiki/Getting-Started

Once both cross and the container engine are installed, you can build your first package: this is all that's required.

$ cargo init --bin hello
$ cd hello
$ cross run --target aarch64-unknown-linux-gnu
   Compiling hello v0.1.0 (/project)
    Finished dev [unoptimized + debuginfo] target(s) in 0.64s
     Running `/linux-runner aarch64 /target/aarch64-unknown-linux-gnu/debug/hello`
Hello, world!
This will automatically install the Rust target required and the Docker image containing the toolchain to cross-compile your target.

When I try to execute the cross run command, I get the following error:

jaspervisser@MacStudanJasper hello % cross run --target aarch64-unknown-linux-gnu
Error: 
   0: `rustup target list --toolchain stable-x86_64-unknown-linux-gnu` failed with exit status: 1

Stderr:
   error: toolchain 'stable-x86_64-unknown-linux-gnu' does not support components

Any suggestions?

sounds like the stable-x86_64-unknown-linux-gnu toolchain is a linked toolchain

what does rustup which --toolchain stable-x86_64-unknown-linux-gnu rustc give you? If it's a folder in .rustup this should probably work.

what you probably need to do is

rustup toolchain uninstall stable-x86_64-unknown-linux-gnu
rustup toolchain install stable-x86_64-unknown-linux-gnu --force-non-host

This has been resolved with #1193, suggesting to reinstall the toolchain if encountered
