# glutin - OpenGL, UTilities and INput
[](https://gitter.im/tomaka/glutin?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
Alternative to GLFW in pure Rust.
[](https://travis-ci.org/tomaka/glutin)
## Try it!
```bash
git clone https://github.com/tomaka/glutin
cd glutin
cargo test
./target/test/window # or target\test\window.exe
```
## Usage
```rust
extern crate glutin;
extern crate libc;
extern crate gl;
fn main() {
let window = glutin::Window::new().unwrap();
unsafe { window.make_current() };
gl::load_with(|symbol| window.get_proc_address(symbol));
gl::ClearColor(0.0, 1.0, 0.0, 1.0);
while !window.is_closed() {
window.wait_events();
gl::Clear(gl::COLOR_BUFFER_BIT);
window.swap_buffers();
}
}
```
## Platform-specific notes
### Android
- To compile the examples for android, initialize the submodules, go to `deps/apk-builder/apk-builder` and run `cargo build`, then go back to `gl-init` and call `ANDROID_HOME=/path/to/sdk NDK_HOME=/path/to/ndk NDK_STANDALONE=/path/to/standalone cargo test --no-run --target=arm-linux-androideabi`
- Events are not implemented
### Emscripten
- Work will start when Emscripten gets updated to LLVM 3.5 (which should happen soon)
### OS/X
- This library compiles for OS/X but calling any function will fail
- Some low-level issues related to Objective C bindings make the implementation difficult to write
- Looking for contributors
### Win32
- Pixel formats are not implemented
- If you don't have MinGW installed, you will need to provide `libgdi32.a` and `libopengl32.a` ; you can put them in `C:\Users\you\.rust`
### X11
- Some input events are not implemented
- Pixel formats not implemented
- The implementation probably needs a cleanup
