regression: "no method named `floor` found for type `f32` in the current scope" #14

Closed astraw closed 4 years ago

astraw commented 4 years ago

Hi, when upgrading from 0.2.0 to 0.2.1 (via "cargo update", for example), the new auto_simd_impl module fails to compile. simba is a transitive dependency of adskalman-rs. The simba requirement is brought in through nalgebra 0.22 with default features disabled and the libm feature enabled.

Here is the relevant part of Cargo.toml:

[dependencies]
nalgebra = {version="0.22", default-features=false, features=["libm"]}

You can look at an example build failure here https://github.com/strawlab/adskalman-rs/runs/1273243793 . Here is the relevant excerpt:

Thank you for noticing and reporting this. I published the version 0.2.2 with a fix, and yanked the version 0.2.1.

astraw commented 4 years ago

Thanks for your immediate action and for all your great work on simba and nalgebra etc. I confirm this solves the issue.
