找不到 gl 板条箱

Question

我正在按照这里的说明进行操作。在示例文件夹中，我使用第一个示例。由于某种原因，控制台说它找不到外部板条箱"gl"。这是我的Cargo.toml的样子。

[package]
name = "hello_world"
version = "0.0.1"
authors = [ "bob <[e-mail]>" ]

[dependencies.gl]
git = "https://github.com/bjz/gl-rs"
[dependencies.glfw]
git = "https://github.com/bjz/glfw-rs.git"
[build-dependencies]
gl_generator = "*"
[dependencies]
gl_common = "*"
[[bin]]
name = "hello_world"

我的 build.rs

extern crate gl_generator;    // <-- this is your build dependency
extern crate khronos_api;    // included by gl_generator
use std::os;
use std::io::File;
fn main() {
let dest = Path::new(os::getenv("OUT_DIR").unwrap());
let mut file = File::create(&dest.join("gl_bindings.rs")).unwrap();
// This generates bindsings for OpenGL ES v3.1
gl_generator::generate_bindings(gl_generator::GlobalGenerator,
                                gl_generator::registry::Ns::Gles2,
                                khronos_api::GL_XML,
                                vec![],
                                "3.1", "core", &mut file).unwrap();
}

您链接到的文档说：

在"[package]"部分下，添加build = "build.rs"

但我在你的Cargo.toml中没有看到这一点.
