upgrade to 1.12 failed with glutin: not found

[woile]

Hi everyone, I just updated to slint 1.12 from 1.11 and I get this error:

Error: Error creating OpenGL display (Ok(
    DisplayHandle(
        Wayland(
            WaylandDisplayHandle {
                display: 0x00005641c528e590,
            },
        ),
    ),
)) with glutin: not found

I'm not sure how to fix it. Things were working fine until now.
If I downgrade to 1.11 the fail continues, this makes me suspect it's a dependency issue. If I restore the lock, things work again

I checked the blog and the changelog, but couldn't find any hints.

My system:
OS: NixOS
DE: KDE

Thanks!

I believe this error originates from glutin when it failed to dynamically load the EGL libraries. From the code:

(egl/mod.rs)

pub(crate) static EGL: Lazy<Option<Egl>> = Lazy::new(|| {
    #[cfg(windows)]
    let paths = ["libEGL.dll", "atioglxx.dll"];

    #[cfg(not(windows))]
    let paths = ["libEGL.so.1", "libEGL.so"];

    unsafe { SymWrapper::new(&paths).map(Egl).ok() }
});

I don't believe those paths/names have changed, but I can only see egl/display.rs producing NotFound when those can't be found. Could you check your system? What's the version of glutin in your lock file when it works?

Thanks for the quick response, but I found I was missing a library libGL, a dependency must've changed

For future referece, I was missing the libGL in my LD_LIBRARY_PATH env in the shell:

pkgs.mkShell {
  # other things
  LD_LIBRARY_PATH = "$LD_LIBRARY_PATH:${
    with pkgs;
    lib.makeLibraryPath [
      wayland
      libxkbcommon
      fontconfig
      libGL
    ]
  }";
}
