Thanks for the update. winit seems to be broken und linux though

[hacknus]

we need the x11 feature on linux now, no?

See my comment on: emilk/egui#5493 (comment)

According to emilk's comment: #5489 (comment) the wayland feature needs to be enabled for eframe. However, when the feature is enabled, I get the following compiling errors on Arch:

error: failed to select a version for the requirement `egui-wgpu = "^0.30.0"`
candidate versions found which didn't match: 0.29.1, 0.29.0, 0.28.1, ...
location searched: crates.io index
required by package `eframe v0.30.0`
    ... which satisfies dependency `eframe = "^0.30.0"` (locked to 0.30.0) of package `egui-file-dialog v0.7.0 (/home/jannis/projects/egui-file-dialog)`
if you are looking for the prerelease package it needs to be specified explicitly
    egui-wgpu = { version = "0.26.0-alpha.2" }

egui-wgpu:v0.30.0 doesn't seem to be on crates.io yet

I don't have permission to push on this branch, so here's a suggestion with the fix for Linux

[bircni]

The question is - do we wanna support Wayland or x11?

[hacknus]

shouldn't this be something that the user can select?

[fluxxcode]

We should support both.

Edit: updated my suggestion to also include x11

[fluxxcode]

shouldn't this be something that the user can select?

Yes, this is just for the examples

[bircni]

@fluxxcode we could also set this as optional dependencies?

[fluxxcode]

No, I don't think that's helpful and rather confusing. eframe is only a dev dependency for the examples and is therefore not included in normal use of the library.
The examples should work on as many systems as possible, just like a normal egui app does.

[hacknus]

maybe document it in the examples Cargo.toml that this is required for linux?

[fluxxcode]

It is the job of eframe to document this correctly, but not of our library. The feature is an eframe feature and since our examples use eframe, we have to "configure" eframe correctly. But the problem has nothing to do with our library.

Will merge the PR now. Thanks!
