Error building template on Mac

[joebain]

Hi, I am trying to build the template repo on my mac, but I'm getting an error during cargo build. I'm excited to try the project out so hopefully someone can help :) The full output is

(base) joe@Josephs-MacBook-Pro rusty-gba % RUST_BACKTRACE=1 cargo build

Hiya! I don't have a Mac available to me, so I'm going to be guessing a bit here :). If we get this working, would you mind writing your setup steps so it can be added to the docs?

Based on that error, I think you're missing the arm-none-eabi binutils. Specifically in this case the arm-none-eabi-as command. Could you check if that is runnable and if not, install it and try again? There appears to be some steps here if they make sense: https://stackoverflow.com/questions/59861085/how-to-install-gcc-arm-none-eabi-at-mojave-macos

Thanks for giving agb a try! Looking forward to seeing what you make and your feedback on the project

That worked, amazing! Thanks for your help, I'll add my steps to the book.
