cfallin opened Issue #1775:

I've set up my environment to do cross-compilation and cross-architecture running of aarch64 tests from x86. This uses qemu in its userspace-emulation mode, as documented in docs/contributing-building.md.

If I try to run tests, I encounter a failure in the peepmatic-macro crate:

[cfallin@cfallin-laptop wasmtime.trunk]$ cargo test -p peepmatic-macro --target aarch64-unknown-linux-gnu --release
   Compiling unicode-xid v0.2.0
   Compiling syn v1.0.18
   Compiling proc-macro2 v1.0.10
   Compiling quote v1.0.3
   Compiling peepmatic-macro v0.1.0 (/home/cfallin/wasmtime.trunk/cranelift/peepmatic/crates/macro)
    Finished release [optimized] target(s) in 26.17s
     Running target/release/deps/peepmatic_macro-30cd4009616cf4d6
/home/cfallin/wasmtime.trunk/target/release/deps/peepmatic_macro-30cd4009616cf4d6: Invalid ELF image for this architecture
error: test failed, to rerun pass '-p peepmatic-macro --lib'

Caused by:
  process didn't exit successfully: `qemu-aarch64 -L /usr/aarch64-linux-gnu -E LD_LIBRARY_PATH=/usr/aarch64-linux-gnu/lib64 /home/cfallin/wasmtime.trunk/target/release/deps/peepmatic_macro-30cd4009616cf4d6` (exit code: 255)

The named binary is an x86-64 ELF binary, so presumably some bit of build glue is just assuming that host == target.

This issue has likely existed for a while, but I only recently encountered it because I'm newly cross-compiling; I was previously using a native aarch64 box that we've lost access to. Our CI tests exclude peepmatic, so this is not critical, but it would be nice for a cargo test --all to work by default when one has the right qemu runner set-up.

peepmatic-macro is a proc-macro, which means that it must be compiled for the host architecture. How did you setup cargo to run tests using qemu?

TBH this actually looks like a bug in Cargo. In the meantime I've opened up https://github.com/bytecodealliance/wasmtime/pull/1778

Er actually, alternatively, this is fixed in nightly Cargo!

Thanks, @alexcrichton!

@bjorn3: I'm using the ~/.cargo/config.toml settings that we added recently in docs/contributing-building.md; basically this gives Cargo the ability to use qemu as a runner automatically.
