This looks like rusterlium/erlang_nif-sys#3.

Try adding

#![feature(link_args)]
#[link_args = "-flat_namespace -undefined suppress"]
extern {}

to the top of the nif.rs file.

Add add above feature code at top of lib.rs like this:

#![feature(link_args)]
#[link_args = "-flat_namespace -undefined suppress"]
extern {}
#![feature(plugin)]
#![plugin(rustler_codegen)]

#[macro_use]
extern crate rustler;
use rustler::{NifEnv, NifTerm, NifError, NifDecoder, NifEncoder};
use rustler::resource::ResourceCell;

    [("add", 2, add),
     ("panic_test", 0, panic_test),

    Some(on_load)

It's fix by adjust the order with:

#![feature(plugin)]
#![plugin(rustler_codegen)]
#![feature(link_args)]
#[link_args = "-flat_namespace -undefined suppress"]
extern {}

#[macro_use]
...

But, it's seems like nif load path is mistake on osx:

Fixed with:

cp ./native/target/debug/librust_nif.dylib to ./native/target/debug/librust_nif.so

or

ln -s ./native/target/debug/librust_nif.dylib ./native/target/debug/librust_nif.so

This seems quite similar to #12!
