The X11-only CI appears to be failing due to a somehow missing waland-client system library. Not sure what's up with that.

softbuffer has this dependency:

wayland-client = {version = "0.29", features = ["use_system_lib"], default_features = false}

I tried adding libwayland-client0 as a dependency... though since winit itself already uses wayland-client with this feature I'm doubtful.

[dhardy]

No surprise, that didn't help:

libwayland-client0 is already the newest version (1.18.0-1).

Strangely, its the x11 build that failed.

Running cargo test --no-run --verbose --target x86_64-unknown-linux-gnu --no-default-features --features x11 (what the command reduces to) on my machine (running X11) works.

Indeed. It's quite strange. Could it be that there's some side-effect softbuffer inadvertently relies on when we enable our Wayland deps? I'm not sure if this is particularly likely, but the X11-only build does seem to be the only Linux build consistently failing.

Personally I'd be a little skeptical of using softbuffer as an example as it has some bugs on Wayland. And there is also the maintenance issue as several issues and pull requests have been opened in the last 2 months without any responses.

I do recall we had a winit-blit project, but that never really took off.

We've forked swbuf under @rust-windowing, so we'll probably want to use that instead - I'll close this for now, esp. also because swbuf doesn't support all of winit's platforms yet (Android and iOS missing), but free to reopen if you update it to use that

[dhardy]

Good to hear that there's a maintained fork. If you'd rather see swbuf support more platforms first then I guess there's no point updating this PR for now.

Randomly found this (branch deletion poked the PR), iOS/MacOS are now supported and Android will be soon: rust-windowing/softbuffer#288

Seems like winit now already uses softbuffer in some examples, but disabled it on these platforms for "some reason" :/
