Rust-SDL2

Bindings for SDL2 in Rust

Overview

Rust-SDL2 is a library for talking to the new SDL2.0 libraries from Rust. Low-level C components are wrapped in Rust code to make them more idiomatic and abstract away inappropriate manual memory management.

Rust-SDL2 uses the MIT license.

If you want a library compatible with earlier versions of SDL, please see here

Where are SDL_image, SDL_mixer, and SDL_ttf?

These live outside of the repo.

Requirements

Rust

We currently compile against the Master branch. I'd recommend using the Nightly installer, as that has the greatest chance of working.

SDL2.0 development libraries

Linux

Install these through your favourite package management tool, or via http://www.libsdl.org/

Ubuntu example:

sudo apt-get install libsdl2-dev

Mac OS X

If you're running OSX, it's a good idea to install these via homebrew

brew install sdl2

If you're having issues, see here.

Windows (MinGW)

On Windows, make certain you are using the MinGW version of SDL; the native version will crash on sdl2::init.

1. Download mingw development libraries from http://www.libsdl.org/ (SDL2-devel-2.0.x-mingw.tar.gz).

2. Unpack to a folder of your choosing (You can delete it afterwards).

3. Copy all lib files from

   SDL2-devel-2.0.x-mingw\SDL2-2.0.x\x86_64-w64-mingw32\lib

   inside

   C:\Rust\bin\rustlib\x86_64-pc-windows-gnu\lib

4. Copy SDL2.dll from

   SDL2-devel-2.0.x-mingw\SDL2-2.0.x\x86_64-w64-mingw32\bin

   into your cargo project, right next to your Cargo.toml.

Installation

If you're using cargo to manage your project, you can download through Crates.io:

    [dependencies]
    sdl2 = "0.0.29"

Alternatively, pull it from GitHub

    [dependencies.sdl2]
    git = "https://github.com/AngryLawyer/rust-sdl2"

Otherwise, clone this repo and run cargo

cargo build

Demo

We have some simple example projects included:

cargo run --example demo

cargo run --example audio-whitenoise

Some additional examples can be found in the rs-sdl2-examples repo.

OpenGL

If you want to use OpenGL, you also need the gl-rs package. If you're using cargo, just add these lines to your Cargo.toml:

    [dependencies.gl]
    git = "https://github.com/bjz/gl-rs"

Then you need to add this to add this initialization code to establish the bindings:

    gl::load_with(|s| unsafe {
        std::mem::transmute(sdl2::video::gl_get_proc_address(s))
    });

Note that these bindings are very raw, and many of the calls will require unsafe blocks.

When things go wrong

Rust, and Rust-SDL2, are both still heavily in development, and you may run into teething issues when using this. Before panicking, check that you're using the latest version of both Rust and Cargo, check that you've updated Rust-SDL2 to the latest version, and run cargo clean. If that fails, please let us know on the issue tracker.
