Describe your issue

I'm running Rust 1.87.0 on Windows 10 with the GNU toolchain.

Default host: x86_64-pc-windows-gnu
rustup home:  (redacted)\.rustup

installed toolchains
--------------------
stable-x86_64-pc-windows-gnu (active, default)
stable-x86_64-pc-windows-msvc

active toolchain
----------------
name: stable-x86_64-pc-windows-gnu
active because: it's the default toolchain
installed targets:
  x86_64-pc-windows-gnu

I updated to the latest Docker, rebooted, and verified that docker was running. I tried to follow the Getting Started steps, which sound pretty simple and straightforward, but I get an error: toolchain 'stable-x86_64-unknown-linux-gnu' may not be able to run on this system.

Because cross bills itself as "zero setup" and none of the cross instructions mentioned this error or indicated that I should add targets, it seems likely there is a problem, so I'm reporting it.

What target(s) are you cross-compiling for?

x86_64-unknown-linux-gnu

Which operating system is the host (e.g computer cross is on) running?

• macOS
• Windows
• Linux / BSD
• other OS (specify in description)

What architecture is the host?

• x86_64 / AMD64
• arm32
• arm64 (including Mac M1)

What container engine is cross using?

• docker
• podman
• other container engine (specify in description)

cross version

0.2.5

Example

cargo install cross
cargo init --bin rust-hello-cross
cd rust-hello-cross/
docker ps -a # verify Docker is running
cross run --target aarch64-unknown-linux-gnu

I get:

error: toolchain 'stable-x86_64-unknown-linux-gnu' may not be able to run on this system
note: to build software for that platform, try `rustup target add x86_64-unknown-linux-gnu` instead
note: add the `--force-non-host` flag to install the toolchain anyway
Error:
   0: couldn't install toolchain `stable-x86_64-unknown-linux-gnu`
   1: `rustup toolchain add stable-x86_64-unknown-linux-gnu --profile minimal` failed with exit code: 1

use cross from main branch, this is a known issue whose fix unfortunately didn't land into 0.2.5

[garretwilson]

use cross from main branch

What does that mean?

I just used cargo install cross from the Getting Started guide. Are you saying that the instructions in the Getting Started guide are incorrect? If so, this issue should be reopened to correct them, or a new ticket opened for that.

[Emilgardis]

follow this, the fix has been merged, but not released

https://github.com/cross-rs/cross?tab=readme-ov-file#installation

cargo install cross --git https://github.com/cross-rs/cross

Thank you for your help. By installing cross from the latest Git main branch, I was able to perform a cross build according to the instructions.

Good luck in putting out a new release soon!

Thank you, it's very much overdue, but time (and sometimes motivation) is expensive!
