Build fails on Raspberry Pi4

[andrewdavidmackenzie]

I am trying to compile my project that uses wasmtie an dhence cranelift on my Raspberry Pi 4 (using rustc 1.67.0-nightly (11ebe6512 2022-11-01)) and I get the following error:

error: failed to run custom build command for `cranelift-codegen v0.89.1`

Caused by:

I couldn't find any information on supported platforms/architectures, so thought I'd ask here.

arm32 (armv7 in the output above) is unfortunately not supported. Wasmtime+Cranelift will run on RPi4 hardware with a 64-bit OS (arm64 aka aarch64 aka ARMv8) though. #1173 tracks this.

Thanks for quick response.
Moving to the new 64bit raspbian may solve the issue, on the same hw then?

Yes, it should! You should be able to download our release binaries for aarch64-linux and use them directly, or build from source, either way.
