Compile Error: unresolved import `crate::arch::x86_64::_mm_movemask_pi8`

[Sp00ph]

When trying to compile a hello world program with packed_simd-0.3.3 as a dependency, I'm getting the following compile error:

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

I'm using rustc 1.50.0-nightly (f76ecd066 2020-12-15) on Windows. Edit: I just tried compiling the same program on Linux (same rustc version) and it gave me the same error

Ok guys I'm just dumb and didn't read the docs, I just imported the old broken version of packed_simd. Sorry guys

[calebzulawski]

No worries, it's a bit confusing!

@Sp00ph can you tell me what you did to remove this error? I am getting the same error while using nightly to build my code.

You need to use packed_simd_2 as a dependency, packed_simd on crates.io is unmaintained

Can you guide me how to make those changes? I tried adding: packed_simd = { version = "0.3.4", package = "packed_simd_2" } to the dependencies. Still, I couldn't resolve the error.

[Sp00ph]

Maybe try cargo clean and then cargo build? I think cargo sometimes messes up when you change dependencies

I tried this but still it isn't resolved. You can check this link I finally managed to resolve it. Thanks for your help.
