[macOS] Following the README file, fails to compile

[skhaz]

I am following the README file, however for macOS it fails to link, step by step below.

export WASI_VERSION=20
export WASI_VERSION_FULL=${WASI_VERSION}.0
wget "https://github.com/WebAssembly/wasi-sdk/releases/download/wasi-sdk-${WASI_VERSION}/wasi-sdk-${WASI_VERSION_FULL}-macos.tar.gz"
tar xvf "wasi-sdk-${WASI_VERSION_FULL}-macos.tar.gz"

The error.

clang-16: error: linker command failed with exit code 1 (use -v to see invocation)

The error occurs because the path is incorrect, below is the correction.

.../lib/libclang_rt.builtins-wasm32.a

Should be.

.../lib/wasi/libclang_rt.builtins-wasm32.a

After copying it to a directory above, I get this error.

wasm-ld: error: cannot open crt1.o: No such file or directory
wasm-ld: error: unable to find library -lc

PS.: Please put the commands with variables in double quotes, as ZSH escapes them when pasting and an error occurs.

you should use wasm32-wasi target instead.

you don't need to specify sysroot or target as they are the default.
