Thanks, looks like this is broken by rust-lang/rust#142885

[samlii]

I think you meant PR rust-lang/rust#143829

[SUPERCILEX]

I'm waiting on emilk/egui#7356 to be able to make a release.

[nunocordeiro]

This issue is marked as closed, but I still see it, on Fedora 42. Please let me know if I can help. I tried several other rustup nightlys but couldn't get it to work.

[SUPERCILEX]

What version of rust are you on? I wonder if you need to upgrade.

[SUPERCILEX]

Oh wait sorry, different repo. Yeah I haven't made a release with the fix yet. You can install from git if you want the fix

[nunocordeiro]

Thanks!

I don't understand why it's closed. I have tried most commits all the way back to 6 months ago. I have tried to run the .sh scripts, I have tried to follow the manual instructions cargo install clipboard-history-wayland --no-default-features gives the same error etc.

[SUPERCILEX]

Not at my computer right now, but cargo install clipboard-history-wayland --no-default-features --git https://github.com/SUPERCILEX/clipboard-history is probably the command.

[nunocordeiro]

It seems like the issue is caused by the sh linked to by curl in the installation instructions FORCING the nightly. If you install a rustup nightly from May, default to it, and then use the same commands in the sh, but without +nightly, it seems to proceed correctly.

Still figuring it out, though, as I am somewhat inexperienced in these things and I've already spent a lot more time on this issue than was expected....

[nunocordeiro]

Managed to get it installed and (mostly) running as advertised. There were some other hiccups along the way that make me think this might not be ready for prime time yet. But it's a good project when it's ready. =)

[SUPERCILEX]

Glad you got it working! Normally egui doesn't take this long to push out bug fixes, so if another person complains I'll downgrade egui so I can make a release. Agreed that this is annoying.
