@ -35,13 +35,16 @@ Next up, you'll want to write a build script like so:
extern crate gcc;
fn main() {
gcc::compile_library("libfoo.a", &["foo.c", "bar.c"]);
gcc::Config::new()
.files(["foo.c", "bar.c"])
.compile("foo");
}
```
And that's it! Running `cargo build` should take care of the rest and your Rust
application will now have the C files `foo.c` and `bar.c` compiled into it. You
can call the functions in Rust by declaring functions in your Rust code like so:
