Where should I place a static library so I can link it with a Rust program?

Question

I do not know how to link a C library to Rust. Here\'s what I have done:

My lib.rs file contains

#[link(name = \"test\")]
extern {
<         


        

Answer 1

I just found a solution (two) but I do not know if it's the best way:

1- way

build.rs file

extern crate gcc;

fn main() {

    println!("cargo:rustc-link-search=native=/home/path/to/rust/proyect/folder/contain/file.a");
    println!("cargo:rustc-link-lib=static=test");
}

Cargo.toml

//..
build = "build.rs"
//..

---

2- way

Cargo.toml

//..
rustc-link-search = ["./src/lib"]
rustc-link-lib = ["test"]
root = "/home/path/to/rust/proyect/"
//..

["./src/lib"] -> place to lib.a refence to root
