error

This was originally found in shadowsocks/shadowsocks-rust#459 .

Auto merge of #2115 - zonyitoo:master, r=JohnTitor

Changed in libc is already merged. Consider fixed the lowest libc version in the next release.

@zonyitoo

Thanks for finding and solving the problem @zonyitoo.

Sorry to borrow this issue, but I found out aarch64-unknown-linux-musl and x86_64-unknown-linux-musl targets are also broken the same way and made a pull request to libc crate to get SO_INCOMING_CPU implemented there.

PR: rust-lang/libc#2119

Bump Rust toolchain

Until the next version of libc is released, is there a known workaround, such as pinning a specific version of libc or socket2?

@fbecart

@fbecart can you run cargo update, updating the libc crate? That should resolve this issue.

@Thomasdezeeuw

Thank you @Thomasdezeeuw for pointing me in the right direction. I realize the problem is currently fixed for a specific set of architectures only. I'm building for i686-unknown-linux-musl, for which an issue likely still exists. I'll redirect my attention to libc.

Auto merge of #2124 - fbecart:master, r=JohnTitor

@Thomasdezeeuw

There are still many architectures missing SO_INCOMING_CPU in the libc crate. Could @Thomasdezeeuw make sure that all Linux-like platforms have this definition in libc?

I am not sure that target-env = "uclibc" has SO_INCOMING_CPU definition. It is left for others to make patches. :)

I think this issue is really with libc, not with socket2.

Auto merge of #2135 - zonyitoo:master, r=<try>

I meet this issue too.

To learn more, run the command again with --verbose.

how to work around?

@JinAirsOs

@JinAirsOs you can disable the all feature for now to work around it. Otherwise I think rust-lang/libc#2135 would fix this issue.
