Build Instructions

You can install Rust with the installer available on rustup.rs. Clone the repository and build the library with the following command:

cargo build --release -p livesplit-core-capi

The library will then be available as a shared and static library in the target folder. If you only want to build the library as a shared or static library, not both, you can run either one of the following commands:

# Shared Library
cargo rustc --release -p livesplit-core-capi --crate-type cdylib
# Static Library
cargo rustc --release -p capi --crate-type staticlib

If you want to build the bindings for the library too, you need to go into the capi/bind_gen folder and run the following command:

cargo run

The bindings will then be available in capi/bindings.


Builds for a lot of common platforms are available in the Releases.
