1 year ago can you try https://github.com/coderedart/egui fork with glutin_winit branch and see if the issue is fixed.

1 year ago Sure, tried next:

1 year ago You need to do cargo clean after that split debug info change.
And are you getting the same glutin error ?

1 year ago I did, it was a git clone&checkout to new directory. It's just boring to watch 5 minute gif, so I built it before the record. Here is the log with cargo clean before the build if you need it

1 year ago I'd be happy to provide any additional info to help to resolve the issue.

1 year ago try setting log level to debug and backtrace to full. on linux, it would be RUST_BACKTRACE=full RUST_LOG=debug cargo run.
it will provide us with more info.

1 year ago I made setting vsync/swap_interval optional so that it won't panic.
can you pull the latest git commits from glutin_winit branch of my fork and try again?

1 year ago Thanks, I updated it to 0e186efb7eff4f4bfcf8001117cadb6a57743221
0e186efb7eff4f4bfcf8001117cadb6a57743221 (HEAD -> glutin_winit, origin/glutin_winit) cranky lint
d5bda4c4af9d8f6f3909f18c81b8d887efdbf0e7 add more logging. ignore vsync option if not supported
c8a130e50dad1bb712faff6cc1fb324cace36402 update pure glow example to use glutin_winitNow the process is crashing with null passed to strlen it seems. Here is the console log:

Now the process is crashing with null passed to strlen it seems.
happening inside glow's get_parameter_string when trying to get opengl shader version string.
To avoid hitting that codepath, we can provide a fixed shader version using native options.
in hello_world/src/main.rs, change native options to
let options = eframe::NativeOptions {
initial_window_size: Some(egui::vec2(320.0, 240.0)),
shader_version: Some(eframe::egui_glow::ShaderVersion::Es300), // explicit shader version so that egui won't query opengl for supported version.
..Default::default()
};If we get another error soon, we need to debug opengl.
can you provide your platform details using https://github.com/gkv311/wglinfo/releases or a screenshot of www.realtech-vr.com/home/glview or something equivalent.
just to make sure that this error is due to glutin/glow and not driver issues, you can try running the basic example in https://github.com/ArjunNair/egui_sdl2_gl which uses sdl2 and raw opengl bindings.
If sdl2/gl works, then we narrow the problem to glutin. you can try running an older version of eframe like 0.19 which uses older glutin versions.
if older version of eframe works, then it could be recent glutin changes causing problems.
in line https://github.com/coderedart/egui/blob/glutin_winit/crates/eframe/src/native/run.rs#L432 change ApiPrefence::FallbackEgl to ApiPrefence::PreferEgl and try again.
If Egl doesn't work, time to ask ping glutin devs for help.

@kchibisov is it possible to factor in both Egl and Wgl features during display creation? as you can see in the above comment's wglinfo.txt, there's Egl with opengl es 3.0 (using angle) with all sorts of extensions, but glutin-winit will still choose Wgl which doesn't have any display features/extensions at all (swap control or robustness etc..).
If it is possible to query the DisplayFeatures or extensions, i think providing them to the config picker closure in https://docs.rs/glutin-winit/0.2.1/glutin_winit/struct.DisplayBuilder.html#method.build might be a nice way to allow users to choose. preferably without having to match the platform gated variants of the config.
according to https://github.com/emilk/egui/pull/2541#issuecomment-1370767582 , glutin doesn't provide code to destroy the created display connections of egl/wgl/glx... so, we can't create two displays and choose the better one, and it may lead to weird to catch bugs.

PreferEglfix might work for you.
Yes, it's some kind of VMWare virtual machine I use for work. I tried making the PreferEgl fix (by editing the source in ~/.cargo and doing a clean build), but it still was trying Wgl. Perhaps that isn't the right way to make that change.

1 year ago Thank you. That makes more sense. I get the same output using my own modified copy.
This line in the logs seems interesting, since it mentions Wgl when I assume it should be Egl with PreferEgl specified:

ANGLE isn't supported by glutin and never was, patches are welcome though(https://github.com/rust-windowing/glutin/issues/1508).

You'd need to create both displays and ask for features each of it. I think you can do such a thing and then drop the displays, but you'd need to add library unloading into glutin to conserve resources.

sure:
It looks like I have the same issue @whee has? No OpenGL devices? I'm using Hyper-V machine for all the logs in this issue. However I have another PC without Hyper-V which has same issue (that machine doesn't have dedicated GPU card, maybe the problem is that I'm connecting to it via RDP?), here is the info from it:
It looks like this RDP machine is showing no OpenGL devices as well. So, what would you recommed, how one can develop with egui in such conditions? Rust run the browser to access the GUI?
coderedart
commented
1 year ago I'm using Hyper-V machine
always mention that. would have saved a lot of time :). perhaps, the issue template should probably be updated to prompt that info along with OS.
anyway, its the same issue. we need to wait until glutin gets angle support (as kchibisov said), then use software glow rendering.
same problem for the RDP. it can't find a driver/device with opengl support.

Seems like you've either used very old glutin or something forced vsync, but modern glutin doesn't require vsync or any extension in any form.

1 year ago I've tried eframe 0.22.0 which depends on glutin 0.30.8.
use eframe::egui;
fn main() -> Result<(), eframe::Error> {
env_logger::init();
eframe::run_simple_native("Hello world", Default::default(), move |ctx, _frame| {
egui::CentralPanel::default().show(ctx, |ui| {
ui.heading("Hello world");
});
})
}wgpu works because it uses DX12.
// eframe = { version = "0.22.0", features = ["wgpu"] }
use eframe::egui;
fn main() -> Result<(), eframe::Error> {
env_logger::init();
let native_options = eframe::NativeOptions {
renderer: eframe::Renderer::Wgpu,
..Default::default()
};
eframe::run_simple_native("Hello world", native_options, move |ctx, _frame| {
egui::CentralPanel::default().show(ctx, |ui| {
ui.heading("Hello world");
});
})
}I've tried with vsync: false and HardwareAcceleration::Off but it makes no difference.

1 year ago This is not a glutin error. virtual box windows only provides opengl 1.1 and that is not enough for egui renderer. So, the crash is explicitly caused by egui_glow.

Your best option is to go with software rendering https://github.com/emilk/egui/issues/1129

1 year ago Personally, i made some experiments on this, and i used https://github.com/rustytsuki/egui which is a fork of egui, with skia backend, using skia feature instead of glow, seems to work well on windows compilation and using. i had a couple of gui, compiled on github plateform : https://github.com/barrelorgandiscovery/virtualbookplayer and https://github.com/frett27/encrypter
This does not resolve the issue, but probably help users using egui on windows plateform for a first step hope this help,
