It feels like it isn't running in Docker?

Can you provide the output of cross --version? Are you installing from git? The latest cross versions will also warn you if you fall back to the host. The latest release on crates.io is quite old and we're planning a release at some point.

If I install cross from git, the following works fine:

$ cargo install cross --git https://github.com/cross-rs/cross
$ git clone https://github.com/cross-rs/rust-cpp-hello-word
$ cd rust-cpp-hello-word
$ cross run --target i686-pc-windows-gnu

   Compiling cc v1.0.73
   Compiling hellopp v0.1.0 (/project)
    Finished dev [unoptimized + debuginfo] target(s) in 42.90s
     Running `wine /target/i686-pc-windows-gnu/debug/hellopp.exe`

Hello, world!

So everything seems to work if using the latest versions.

$ cross --version
cross 0.2.1
cargo 1.61.0 (a028ae42f 2022-04-29)

$ cross --version
cross 0.2.1
cargo 1.61.0 (a028ae42f 2022-04-29)

Yeah that means you're using the very old version installed from crates.io, which has some major bugs we're fixing in a new release. For a while, we had a lack of maintainers, so we've been patching some errors that had built up over time. If you reinstall cross from git (as shown above), this should fix your issue. You can always use a specific commit if you'd like to lock version dependencies. For example, to use the currently latest commit, and ensure you've audited the correct version, use:

cargo install --git https://github.com/cross-rs/cross --rev 6a7fa09d6307acb5380475b134ff749c7cd9ed35

This will also warn you if any commands fall back to the host:

cross --version
cross 0.2.1 (6a7fa09 2022-06-05)
Warning: Falling back to `cargo` on the host.
cargo 1.61.0 (a028ae42f 2022-04-29)

Thanks for your patience with the lack of recent releases, due to the lack of maintainers.
