embree3-arm

Rust bindings to Embree. Forked from embree-rs, and relinked by dynamical lib generated from Embree on MacOS with arm architecture. Only apply for using the embree-rs in v0.3.8 edition on MacOS arm.

Usage

When trying to extern crate embree3_arm as embree, follow these steps:

1. add this build.rs in the workspace of the rust program:

use std::env;
use std::path::PathBuf;

fn main() {
    println!("{:?}", env::var("EMBREE_DIR"));
    if let Ok(e) = env::var("EMBREE_DIR") {
        let mut embree_dir = PathBuf::from(e);
        embree_dir.push("lib");
        println!("cargo:rustc-link-search=native={}", embree_dir.display());
        println!("cargo:rerun-if-env-changed=EMBREE_DIR");
    }
    println!("cargo:rustc-link-lib=embree3");
}

2. Set the workspace to the following env variable:

export EMBREE_DIR=`pwd`

3. Download compressed libembree from github release page, and move the lib folder to the root dir of rust program.

4. cargo build && cargo run, then copy libembree3.3.13.4.dylib, libembree3.3.dylib and libembree3.dylib to ./target/debug or ./target/release

5. try cargo run again.
