linking with `cc` failed: exit code: 1

Hi im just trying to compile the following with stdweb 
```
#[macro_use]
extern crate stdweb;

fn main() {
    let message = "Hello, WASM";
    js! {
        console.log( @{message} )
    }
}
```
Gives me the following error 
```linking with `cc` failed: exit code: 1```
