The build instructions highlight how to use this. We don't invoke docker build directly, and the build system requires code from cross itself.

git clone https://github.com/cross-rs/cross
cd cross
git submodule update --init --remote

Then, after you've initialized the cross-toolchains submodule within cross itself, use cross's tools to build the image:

cargo build-docker-image x86_64-pc-windows-msvc-cross

This happens because we want to share assets with those in cross/docker, which we use as Docker context (basically, the root of where Docker searches for files in). Let me know if this fixes the issue.

🤦‍♂️ my bad.

man_facepalming my bad.

No worries. Let me know if you still have issues and I'll reopen this.
