1# Add `bindgen` as a Build Dependency 2 3First we need to declare a build-time dependency on `bindgen` by adding it to 4the `[build-dependencies]` section of our crate's `Cargo.toml` file. 5 6Please always use the latest version of `bindgen`, it has the most fixes and 7best compatibility. At the time of writing the latest bindgen is `0.53.1`, but 8you can always check [the bindgen page of 9crates.io](https://crates.io/crates/bindgen) to verify the latest version if 10you're unsure. 11 12```toml 13[build-dependencies] 14bindgen = "0.53.1" 15``` 16
