Unable to compile hello_world.rs to wasm

Following the tutorial here I've installed Rust and Emscripten. But when I try to compile a simple rust file to WebAssembly I get an error from llvm-ar. I'm a total noob to Rust, enthused by the idea of a web language that doesn't suck, so apologies if I've missed something obvious. I'm on macOS Sierra 10.12.5:

error: aborting due to previous error
nikgraf commented
I'm having the same issue.
rustup 1.6.0, emcc 1.37.21, osx 10.12.6
Command:
cargo build --target=wasm32-unknown-emscripten
Code:
fn main() {
println!("Hello world!");
}
gliheng commented
Run into the same issue on mac 10.12.6, rustc version 1.22.1.
This may be an issue of emcc, as I see the same error from running one of official tutorials.
aaronshaf commented
Same issue here.
chicoxyzzy commented
It looks like this was fixed on Emscripten side emscripten-core/emscripten#5418
alexcrichton commented
A pretty huge amount has changed since this was first opened, so I'm going to close this as "pretty likely stale". If it reproduces still though feel free to reopen!
