Cannot compile coresimd with cargo

[rococtz]

Hi,

I have just tried added stdsimd to my Cargo.toml dependencies:

[dependencies]
stdsimd = "*"

and perform cargo run but it fails with hundreds of erros:

60 | #[target_feature = "+xsave,+xsaveopt"]
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

error: #[target_feature] attribute must be of the form #[target_feature(..)]
  --> C:\Users\office\.cargo\registry\src\github.com-1ecc6299db9ec823\coresimd-0.0.4\src\x86\x86_64\xsave.rs:73:1

error: Could not compile `coresimd`.

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

My current versions:

rustup 1.11.0 (e751ff9f8 2018-02-13)
rustc 1.28.0-nightly (cbc4c8380 2018-06-22)
cargo 1.28.0-nightly (e2348c2db 2018-06-07)
Windows 10 (with Command Prompt)

looks like for some reason these weren't updated

This isn't trying to compile master. This is trying to compile stdsimd from crates.io.

What problem are you trying to solve? You generally shouldn't be using this crate directly.

[gnzlbg]

You have to use the master branch from git. The correct thing to do to use stdsimd directly is:

[dependencies]
stdsimd = { git = "https://github.com/rust-lang-nursery/stdsimd.git" }

Need to add this to the README.md

[rococtz]

What I am actually trying to do is to install rustface from crates.io which fails because stdsimd fails to compile. I have raised this issue with them.

To quote the guys from rustface:

Seems to me like current simd version is outdated and incompatible with current Rust version

[BurntSushi]

I see. rustface needs to stop using stdsimd on crates.io.
