Not able to "cargo build" successfully

[AchalaSB]

I am running cargo build command after cloning the repo. But getting this build error. gcc, cmake, build-essential are installed & in the PATH. All help appreciated, thanks in advance.

error: failed to run custom build command for `mir2wasm v0.1.0 (file:///home/achala/GIT/mir2wasm)`
process didn't exit successfully: `/home/achala/GIT/mir2wasm/target/debug/build/mir2wasm-241ea3cc3cdec5b2/build-script-build` (exit code: 101)

Same here for MAC OSX. Should there be a Makefile in the target definition. Someone please help. TIA

Since it's a problem building binaryan maybe updating the binaryan submodule would help.

I'm afraid I don't maintain this repo anymore (and it never accomplished anything particularly useful) but if somebody else wants it I'd be happy to transfer it to them.

[kripken]

There are Binaryen bindings for Rust here, maybe that can help: https://github.com/pepyakin/binaryen-rs

Would it be possible to add a note in README saying that if you do want WASM, you should "just" use the nightly? (and maybe link to a guide for this, if one exists)

EDIT: link is https://rustwasm.github.io/book/

I've done so, and changed the repo description to warn people away.
