Regression introduced in 47df0e9eaa
Casting fullscreen_atom (which is the result from XInternAtom, i.e.
c_ulong) as i64 is obviously wrong -- the whole point of types such as
c_ulong is that long in C does *not* always have the same bit size...
Cast it as c_long instead.
While this is the most straightforward fix, I'm not sure it's the best
one: perhaps the x11 crate should offer a set_ulong() method along with
set_long(), which could be used here instead of the cast?
glutin - OpenGL, UTilities and INput
Alternative to GLFW in pure Rust.
[dependencies]
glutin = "*"
Documentation
Try it!
git clone https://github.com/tomaka/glutin
cd glutin
cargo run --example window
Usage
Glutin is an OpenGL context creation library and doesn't directly provide OpenGL bindings for you.
[dependencies]
gl = "*"
libc = "*"
extern crate gl;
extern crate glutin;
extern crate libc;
fn main() {
let window = glutin::Window::new().unwrap();
unsafe { window.make_current() };
unsafe {
gl::load_with(|symbol| window.get_proc_address(symbol));
gl::ClearColor(0.0, 1.0, 0.0, 1.0);
}
for event in window.wait_events() {
unsafe { gl::Clear(gl::COLOR_BUFFER_BIT) };
window.swap_buffers();
match event {
glutin::Event::Closed => break,
_ => ()
}
}
}
Note that glutin aims at being a low-level brick in your rendering infrastructure. You are encouraged to write another layer of abstraction between glutin and your application.
Platform-specific notes
Android
- To compile the examples for android, initialize the submodules, go to
deps/apk-builder/apk-builderand runcargo build, then go back toglutinand callANDROID_HOME=/path/to/sdk NDK_HOME=/path/to/ndk NDK_STANDALONE=/path/to/standalone cargo test --no-run --target=arm-linux-androideabi
X11
- The plan is that glutin tries to dynamically link-to and use wayland if possible. If it doesn't work, it will try xlib instead. If it doesn't work, it will try libcaca. This is work-in-progress.
