Fail Compilation with Rust Nightly.

[icommit]

net2 is a dependent crate for hyper- Rust http library. I'm trying to compile the hyper crate with the Rust nightly compiler but the error messages I'm getting seems to be coming from this crate.

error[E0432]: unresolved import sys
--> /home/myUsername/.cargo/registry/src/github.com-1ecc6299db9ec823/net2-0.2.32/src/tcp.rs:18:5
|
18 | use sys::c;
| ^^^ Maybe a missing extern crate sys;?

There is at least 245 similar errors from this crate.

Same here. I'm now on 1.28.0-nightly (84804c387 2018-06-26), but was getting this while running 1.28.0-nightly (e2348c2db 2018-06-07) too.

Seeing this with: rustc 1.32.0 (9fda7c223 2019-01-16)

Hey guys, I don't have this problem anymore - I've just done a stupid mistake. Check if you compile it with correct target - e.g. cargo build --target x86_64-pc-windows-msvc instead of default one (in my case it was wasm32-unknown-unknown configured in a parent folder in .cargo/config)

But what if that is your intended target?

But what if that is your intended target?

If you think wasm32-unknown-unknown - it isn't possible (?), see list of supported platforms: https://github.com/rust-lang-nursery/net2-rs/blob/master/src/lib.rs#L64. Probably wasi is the nearest option but I've never used it, just tip.
