NoGlutinConfigs

[IronOxidizer]

Version

• eframe = { version = "0.22.0" }
• OS: Debian 11 Kernel 5.10
• minimal reproducible example: https://github.com/IronOxidizer/gui-toolkit-benchmarks/tree/main/toolkits/Rust/egui

Describe the bug

eframe should only depend on libgtk-3-0, but for some reason, it depends on the dev library, libgtk-3-dev. I get the following error when launching my minimal egui + eframe application without libgtk-3-dev:

Error: NoGlutinConfigs(ConfigTemplate { color_buffer_type: Rgb { r_size: 8, g_size: 8, b_size: 8 }, alpha_size: 8, depth_size: 0, stencil_size: 0, num_samples: None, min_swap_interval: None, max_swap_interval: None, config_surface_types: WINDOW, api: None, transparency: false, single_buffering: false, stereoscopy: None, float_pixels: false, max_pbuffer_width: None, hardware_accelerated: None, max_pbuffer_height: None, native_window: Some(Xlib(XlibWindowHandle { window: 77594627, visual_id: 0 })) })

To Reproduce
Steps to reproduce the behavior:

1. Install libgtk-3-0
2. Launch the application
3. Error is thrown

Expected behavior

1. Install libgtk-3-0
2. Launch the application
3. Window is displayed

Current workaround

1. Install libgtk-3-dev
2. Launch the application
3. Window is displayed

Is this only when using the glow backend? Perhaps this should be raised in the glutin repository instead?

I'm trying to build an AppImage on a Debian docker image. It builds fine, but when I copy it over to my (arch linux) host, I'm getting a similar problem:

NoGlutinConfigs(ConfigTemplate { color_buffer_type: Rgb { r_size: 8, g_size: 8, b_size: 8 }, alpha_size: 8, depth_size: 0, stencil_size: 0, num_samples: None, min_swap_interval: None, max_swap_interval: None, config_surface_types: ConfigSurfaceTypes(WINDOW), api: None, transparency: false, single_buffering: false, stereoscopy: None, float_pixels: false, max_pbuffer_width: None, hardware_accelerated: None, max_pbuffer_height: None, native_window: None }, Error { raw_code: None, raw_os_message: None, kind: BadConfig })

I can build an run the application on Arch just fine. Did I miss to install some library?
