cross run interprets the program's arguments as its own (ignores --).

Describe your issue

(Not entirely sure if this should be an issue report or a feature request).

When a binary being run with cargo run takes arguments, you can tell cargo where its arguments end and where the program's arguments begin with --, e.g. cargo run --cargo-argument -- --program-argument.

cross does not currently do this, and it interprets --program-argument for itself, as well as passing it to the program. This was most noticeable for me with -v, since cross's verbose textual output to stdout interfered with a program's piped stdout.

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

No response

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

cross 0.2.4

Example

git clone https://github.com/zachs18/cross-rs-argument-example
bash test.sh

The repo contains a simple program:

fn main() {
    match std::env::args().nth(1) {
        None => println!("No arguments passed!"),
        Some(s) => if s == "-v" {
            println!("Verbose (-v) passed!");
        } else {
            println!("Something else ({s}) passed!");
        },
    };
}

The test.sh script calls cargo run and cross run --target=aarch64-unknown-linux-gnu (the specific target doesn't matter) with -- -v (and other argument configurations) to show the difference with cargo, e.g.

$ cargo run -- -v
// normal cargo output, followed by
Verbose (-v) passed!

$ cross run --target=aarch64-unknown-linux-gnu -- -v
// *verbose* cross output, followed by
Verbose (-v) passed!

$ cross run --target=aarch64-unknown-linux-gnu -v -- -v
// verbose cross output, followed by
Verbose (-v) passed!

expected:

$ cargo run -- -v
// normal cargo output, followed by
Verbose (-v) passed!

$ cross run --target=aarch64-unknown-linux-gnu -- -v
// *normal* cross output, followed by
Verbose (-v) passed!

$ cross run --target=aarch64-unknown-linux-gnu -v -- -v
// verbose cross output, followed by
Verbose (-v) passed!
