wasm3 support for arm64 (Apple Silicon, M1)

[wesleyhales]

wasm3-rc won't compile on new aarch64/arm64 target. Here's the error:

Updating crates.io index Compiling cc v1.0.66 Compiling shlex v0.1.1 Compiling cty v0.2.1 Compiling wasm3-sys v0.1.2 (/Users/wesleyhales/dev/wasm3-rs/wasm3-sys) error: failed to run custom build command for wasm3-sys v0.1.2 (/Users/wesleyhales/dev/wasm3-rs/wasm3-sys)

I originally reported the issue here... see comments on why I brought it to this repo.

I tried to build wasm3 standalone and there are issues with unrecognized flags on arm64. After running cmake, I had to edit the build file to remove the -march=native flag completely and replace -fuse-ld=lld with -fuse-ld=ld. wasm3 successfully built after these changes.

[Veykril]

The panic you are getting there is the following line, https://github.com/Veykril/wasm3-rs/blob/master/wasm3-sys/build.rs#L22. I assume you were trying to build it locally in which case you have to clone the submodule for this to build as the error message there implies it cant find the C soure.

As an additional note this crate doesn't make use of the original cmake but solely relies on the build script, so it might need tweaks as well to build for your platform.

[wesleyhales]

Will give it a try and let you know.

@wesleyhales did you ever get wasmcloud to build on an M1 machine? Would love a helping hand if so...I'm a bit out of my depth here but found this issue and looks like it's exactly the culprit for me:

@matthewtgilbride not yet. I think #22 or #21 are related and compile flags need to be passed in to support the M1. That issue talks about different flags for a different problem but I think the problem with passing the arguments are related. I really want to get back to this, so let me know if you make any progress.

[matthewtgilbride]

@wesleyhales this stuff is a bit over my head (learning Rust...with stretch goals to run this project on wasmCloud...but keeping the wasm dependencies isolated for now).

My current workaround here: https://github.com/matthewtgilbride/codenames/blob/main/service/Dockerfile.wash

You'll see there's a docker-compose.yml in the same directory... docker-compose run wash ...start a shell in that container wash up -h nats ...runs the wash cli tool.

My experience with the Docker preview for M1 so far has been quite positive. Obviously you'd need to mount a volume or copy your actor .wasm into the container...but this at least unblocks my use case for now.

Hope that helps...LMK.

[matthewtgilbride]

Hi @Veykril , it appears that wasm3 has released support for M1: https://github.com/wasm3/wasm3/releases/tag/v0.5.0

I don't really understand the codebase here so forgive me if this question is somewhat ignorant. It appears you point to wasm3 as a git submodule here: https://github.com/wasm3/wasm3-rs/tree/master/wasm3-sys

Is it as simple as updating the sha of that submodule to v0.5.0 of wasm3 to close this issue, or is it more complex than that?

[Veykril]

Assuming nothing of the api that the crate uses got changed since the last update it should suffice to just update the sys-bindings I believe

[Veykril]

Just checked and some things have changed for it to not compile as is unfortunately(most likely since the crate relies on some internal things still, which might not be needed anymore). I don't know if these are simple to fix or not. error output:

[vshymanskyy]

Not sure what to do with ffi::_bindgen_ty_1::* errors. The original issue was refering to 'failed to read wasm3/source directory', this was fixed by removing the submodule and including the wasm3 source code directly.

The original issue was refering to 'failed to read wasm3/source directory', this was fixed by removing the submodule and including the wasm3 source code directly.

That is usually caused when not pulling the submodule sources.
