Describe your issue

I’m building a Rust project on an x86_64 host using cross for the aarch64-unknown-linux-gnu target. One of the dependencies, libgssapi, generates Rust bindings from C headers at build time. These bindings are produced based on the host environment, but cross compiles the project inside an aarch64 container. As a result, the bindings are incompatible with the target architecture, causing a build failure due to an architecture mismatch.

As you can see in the screenshot, the path is of host system i.e x86_64

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

aarch64-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

cross 0.2.5

Example

cargo init test_cross
cargo add libgssapi
cargo add libgssapi-sys
cross build --target aarch64-unknown-linux-gnu

Additional information / notes

The project builds successfully when run inside an arm64 Docker container using QEMU for emulation.
