Linker error on macos "discarding .shstrtab section is not allowed"

[junewunder]

currently I'm getting an error on macOS that's preventing me from building the template project. it seems to be a linker error so I'm not sure how to debug it. I have installed arm-embedded via brew install --cask gcc-arm-embedded so now I have commands arm-none-eabi-* on my PATH.

steps to reproduce:

1. clone repo
2. cd template
3. cargo build

error: linking with `rust-lld` failed: exit status: 1

error: could not compile `agb_template` (bin "agb_template") due to previous error

thank you! looking forward to using this library

Hey! These are relating to a bunch of issues we've had recently from Rust updates. This one in particular is resolved by a currently open PR (#403), however even with fixing this one there is another issue!

For now, I would recommend using a slightly older nightly. You can do this by changing the content of the rust-toolchain.toml file to

[toolchain]
channel = "nightly-2023-03-24"
components = ["rust-src", "clippy", "rustfmt"]

which will use the nightly Rust as of 2023-03-24.

that worked! thank you for the quick reply :)
