Unfortunately the rust3ds-template is pretty out of date and probably does not work with cargo-3ds at all.
We are in the midst of reorganizing the rust3ds organization, hopefully to make it less confusing to get started and archive some of the old repos (like rust3ds-template) that are no longer needed to get everything building...
For now, the simplest quick-start option is probably to clone https://github.com/Meziu/ctru-rs (which we are working to upstream to the rust3ds org) and try to cargo +nightly 3ds build some of the examples there: https://github.com/Meziu/ctru-rs/tree/master/ctru-rs/examples
As far as I know, those should mostly work with just ctru-rs as a dependency, which hopefully gives you a starting point to work from? We could probably stand to update the README here to make it more obvious how to get started, so perhaps this issue can be used to track that work.
Let me know if you have troubles, I'd like to make it as simple as possible for people to start using cargo-3ds and related libraries, so docs improvements should be forthcoming!

Hmm, after trying myself I realize there seems to have been a regression in std nightly for horizon (similarly, ESP-IDF and Redox had fixes around this): rust-lang/rust@e86c128
If you try with an older nightly (e.g. nightly-2022-07-18), it should work... we'll have to open a PR upstream to fix it in future versions.

Thanks for looking into this. I will try switching to a different nightly and attempt compiling again. I'll let you know if everything works.

I am able to compile the Rust source for the hello world example from the Meziu repository but the linker fails with the following error:
error: linking with `arm-none-eabi-gcc` failed: exit status: 1

I've made a fix in my local repository (it's just 2 lines of #[cfg]). I will PR it.

I am able to compile the Rust source for the hello world example from the Meziu repository but the linker fails with the following error:
This shouldn't happen in a clean install. I'd suggest to cargo clean the project and retry. Otherwise, check your installation (correct rust-src installed, latest devkitARM etc.). What were your installation steps? @spencerelliott

Hi @Meziu, I used the devkitPro pacman command to install the latest version of devkitARM along with the examples. To install the Rust toolchain, I ran the following commands:
rustup install nightly-2022-07-18
rustup +nightly-2022-07-18 component add rust-src
cd <project directory>
rustup override set nightly-2022-07-18
cargo clean
cargo update
cargo 3ds build
While I was writing out these steps, I also looked at my Cargo.toml file and I removed the following lines that were in the rust3ds-template project:
[profile.dev]
lto = true
[profile.release]
lto = true
Now, I am able to compile the 3dsx file 👍 I guess the link-time optimizations were removing needed methods.

Indeed. Because of some issues with how the libraries are linked, lto breaks some workarounds we are currently using (mainly to link a library after it’s used…). It’s weird really, but we could not find any other way, even with the help of Rust’s maintainers.
