@Thomasdezeeuw can you please look here?

[Thomasdezeeuw]

Can you confirm that it now works without RUSTFLAGS?

Also could you add Solaris to

mio/.github/workflows/ci.yml

Line 155 in e80c3b2

target: ["armv7-sony-vita-newlibeabihf"]

? Then we can make sure it builds.

I can confirm that cargo test --features="log,os-poll,os-ext,net" passes on Solaris 11.4.

@psumbera can you fix the CI?

Not really sure... I can reproduce it on Linux. But now I don't know what to do...

Why it's failing for armv7-sony-vita-newlibeabihf even without my changes?

[Thomasdezeeuw]

Maybe try (I don't have my regular dev setup atm, so can't test)

diff --git a/src/sys/unix/mod.rs b/src/sys/unix/mod.rs

Now I'm getting (with --features os-poll) following. Not sure what to do with it.

I think this might be known Rust issue: rust-lang/rust#115966 . Adding #[warn(unused_imports)] seems to resolve the issue for now.

Though not sure what is status of CI now?

I see now new results. Thank you! The only failure is MSRV (ubuntu-latest). Have no idea what is wrong there...

[psumbera]

@Thomasdezeeuw can this be merged now please?

[Thomasdezeeuw]

This doesn't make sense. Did you mean to disable the lint? That would be the following, but really we shouldn't need it at all.

Suggested change

	#[warn(unused_imports)]
	#[allow(unused_imports)]

[psumbera]

Yes, #[allow(unused_imports)] does make sense. Fixed.

Thanks @psumbera
