## Cross-Compilation ## Cross-Compilation
Cross compilation is possible with this project, if you do not have a Raspberry Pi available specifically for compilation. Compilation directly on the Pi is rather intensive, and takes significantly longer than cross-compiling. However, cross-compiling by default will fail, due to a bad linker. Cross compilation is possible with this project, if you do not have a Raspberry Pi available specifically for compilation. Compilation directly on the Pi is rather intensive, and takes significantly longer than cross-compiling.
To resolve this issue, find the `.cargo` folder. For Windows users, it is located in `C:\Users\[username]`, and for Linux users it is located in `~` or `$HOME`. If you are on Linux, you will need to be sure to show hidden files. If you are compiling on Linux, cross-compilation has a dependency of `lld`. This can be found in your distribution's package manager, or directly distributed by LLVM.
In this `.cargo` folder, create a new file, named `config`. In it, add the following lines in the relevant sections below. If you are compiling on Windows, to safely cross-compile, you must modify the `.cargo/config.toml` file. Replace `lld` with `rust-lld`, then cross-compilation should work properly.
Once this file is added, you can then run one of the following commands to create the executable. Note that the final executable will be in `target/aarch64-unknown-linux-musl`, rather than `target`.
```bash ```bash
cargo build --target aarch64-unknown-linux-musl cargo build --target aarch64-unknown-linux-musl

Make sure `lld` is installed as well. This can be found in your distribution's package manager, or directly distributed by LLVM.
