Can't build the repo

[LijieZhang1998]

Hi, when I followed the instruction to build the repo on macOS, I got the error below. I also tried it on ubuntu, and got the similar error. Any idea? Thanks

warning: [email protected]: error: unable to create target: 'No available targets are compatible with triple "wasm32-unknown-wasi"'
warning: [email protected]: 1 error generated.

error: failed to run custom build command for `ring v0.17.7`

I tried to add the target "wasm32-unknown-wasi" to rust by rustup target add wasm32-unknown-wasi. I got another error:

error: toolchain 'stable-aarch64-apple-darwin' does not support target 'wasm32-unknown-wasi'
note: you can see a list of supported targets with `rustc --print=target-list`
note: if you are adding support for a new target to rustc itself, see https://rustc-dev-guide.rust-lang.org/building/new-target.html

On my apple silicon mac, a build with docker works for me. Give it a try.
docker run --rm -v$PWD:/wasmedge-quickjs -w/wasmedge-quickjs -ti rust bash

 rustup target add wasm32-wasi
 apt-get update && apt-get install clang
 cargo build --target wasm32-wasi --release

Regarding the issue of compiling on macOS, this is a problem with ring and Rust. To put it simply, the solution is to download wasi-sdk and then use the clang included in wasi-sdk for compilation.

export CC="${WASI_SDK_PATH}/bin/clang --sysroot=${WASI_SDK_PATH}/share/wasi-sysroot"
cargo build --target wasm32-wasi --release
