Hi! I'm having some troubles in setting everything up in a Unix environment. I'm pretty new to it all, but I think I installed GCC correctly using homebrew. I have my Nucleo stm32f446 which I'd like to use but I've been getting some error messages. When following along, I'm stuck here:

After entering ./target/build/build.sh stm32f446 rebuild
i get the error

Are you familiar with what this would mean? Thanks for any help!
