Hi Ty, I just tried this out, and it looks like you need to say "target/release/libembed" -- note the added "lib". Once I added that, your program worked fine and printed everything out.
I wonder if the problem you're seeing is that DrRacket is sending the Rust output somewhere else. Can you try running the program with just `racket myprogram.rkt`?
