I'm currently using rust 1.66

While compiling example programs from this repo

all folder shows the same error, as given below.

C:\Users\Sujith\Documents\Projects\rust_projects\egui\egui\examples\retained_image>cargo run
warning: C:\Users\Sujith\Documents\Projects\rust_projects\egui\egui\crates\eframe\Cargo.toml: unused manifest key: target.cfg(not(target_arch = "wasm32")).dependencies.glutin.es

I'm new to rust, so please tell me if I have made any mistake or something I've to follow to get the example programs running.

Try to run cargo clean in your working copy or just remove the target folder. I've also encountered some strange errors in my project when I upgraded to Rust 1.66, probably because the format of the incremental compilation cache was changed.

[SujithChristopher]

Sorry for the delayed reply @Mingun , I have tried that, the results remain the same. Maybe I should try with other versions of Rust, and see if that helps.

Edited
Tried with Rust 1.65.0, The issue remains the same.

you might try commenting out line 30 in the top level Cargo.toml file. see rust-lang/rust#103976.

Thanks @kkoski, It works after commenting line 30.
