User expected to see this happen: a reasonable version output

Instead, this happened: the above linking/loading failures.

[Noratrieb]

Could it be that the user hasn't installed musl? Given that they are on ubuntu using a musl toolchain (which is very weird anyways, they should be using a musl target).
Since we do link musl dynamically on the musl toolchain.

So I guess this issue is a request for a better error message? Or a warning when using a non-host toolchain? I don't quite understand what is expected here.

[fenhl]

A better error message would certainly be useful. I have the toolchain installed because I need to use it as a target. I ran into this issue while trying to run cargo sweep -i, see holmgr/cargo-sweep#102.

[Noratrieb]

I don't think there is much rustc can do with an error message. The error happens before rustc gets to do anything. But maybe the rustup proxies should display a warning when using a non-host toolchain?

The rustc toolchain performs cross-compilation natively, it is not necessary to install a toolchain that differs from your host. Please post any bugs you encounter while cross-compiling from a host gnu toolchain to a musl target.

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:

  /home/<user>/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

  /home/<user>/.cargo

This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:

  /home/<user>/.cargo/bin

This path will then be added to your PATH environment variable by
modifying the profile files located at:

  /home/<user>/.profile
  /home/<user>/.bashrc

You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Current installation options:


   default host triple: x86_64-unknown-linux-musl
     default toolchain: stable (default)
               profile: default
  modify PATH variable: yes

1) Proceed with standard installation (default - just press enter)
2) Customize installation
3) Cancel installation

Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).

To configure your current shell, you need to source
the corresponding env file under $HOME/.cargo.

This is usually done by running one of the following (note the leading DOT):
. "$HOME/.cargo/env"            # For sh/bash/zsh/ash/dash/pdksh
source "$HOME/.cargo/env.fish"  # For fish

Environment check

$ . ~/.cargo/env

[workingjubilee]

@Berbe Debian is a glibc host. You must use the x86_64-unknown-linux-gnu host toolchain. If you go out of your way to install the musl host, then you get a host that is meant to be run on a musl distro. You are bypassing the rustup shell installer to run a binary that happens to be statically linked, but the host toolchain is dynamically linked, because it's for Alpine and the like.

Really, we can't actually solve this any more than we can solve people trying to run the Windows host on their Mac, and we get the same class of errors. Closing.
