Have you installed the command line tools for xcode? On my M1 I get further than this, but I have another problem with wasmer requiring AVX support.

[marco-sundsk]

I have encountered the same problem, and my rust toolchain is stable-aarch64-apple-darwin (default).
The error msg shows on my M1 is:

error[E0425]: cannot find function `get_fault_info` in this scope
   --> /Users/haosun/.cargo/registry/src/mirrors.ustc.edu.cn-61ef6e0cd06fb9b8/wasmer-runtime-core-near-0.17.1/src/fault.rs:289:21

And no other error output.

@austinabell Hey Austin, could you please check this issue?

this issue may be relevant: wasmerio/wasmer#1832 (thought it's about iOS, not Mac M1)

@austinabell Hey Austin, could you please check this issue?

Yeah, I believe this is just an issue of llvm/clang being not configured correctly or the path to llvm binaries not being set up. Setting this up is a bit opinionated, whether or not you want to use brew or not, and I don't personally have an M1 to check the minimal setup (is the file architecture the same as other intel mac?).

This should error even after this when using sim tests though because I believe sim tests are still using the version of nearcore which compiles the version of wasmer which is incompatible with m1, but I believe @willemneal might have the correct status of this.

[myklemykle]

I can confirm: sim tests are still broken on M1, with this same get_fault_info error.
