Conflicting implementations of trait

[christian-vorhemus]

I tried to build the simple sample from the kiss3d front page http://kiss3d.org/

My Cargo.toml looks like this

[package]
name = "main"
version = "0.1.0"
authors = ["Christian"]
edition = "2018"

[dependencies]
kiss3d = "0.8"

When I run cargo build, I get the error

error[E0119]: conflicting implementations of trait `std::ops::Mul<&_>` for type `geometry::translation::TranslationBase<_, _, _>`:

Does someone know how this can be fixed?

You need to update your project to use a more up-to-date version of Kiss3d. Version 0.8 is ancient. The current latest version is 0.24.1.

Indeed, upgrading to 0.24.1 helped, thanks!
