我的 build.rs 脚本在我的 CI 管道 (Azure Pipelines) 中失败,但在本地运行它工作正常。我特别知道我无法生成我的 cbindgen 标头,但错误消息只是列出了它解析的文件,并没有真正说明它失败的原因。
构建.rs:
extern crate cbindgen;
use cbindgen::Config;
use std::env;
use std::path::PathBuf;
fn main() {
let crate_dir = env::var("CARGO_MANIFEST_DIR").unwrap();
let build_ffi = env::var("CARGO_GENERATE_FFI").unwrap();
if build_ffi == "True" {
let output_file = target_dir().join("smartscreen.h").display().to_string();
let config = Config::from_file("cbindgen.toml").unwrap();
cbindgen::generate_with_config(&crate_dir, config)
.unwrap()
.write_to_file(&output_file);
}
}
/// Find the location of the `target/` directory. Note that this may be
/// overridden by `cmake`, so we also need to check the `CARGO_TARGET_DIR`
/// variable.
fn target_dir() -> PathBuf {
if let Ok(target) = env::var("CARGO_TARGET_DIR") {
PathBuf::from(target)
} else {
PathBuf::from(env::var("CARGO_MANIFEST_DIR").unwrap()).join("target")
}
}
cbindgen.toml:
language = "C"
[parse]
parse_deps = false
include = ["src/lib.rs"]
exclude = ["src/urlrep.rs", "src/core.rs", "src/service.rs", "src/smartscreen.rs"]
clean = true
extra_bindings = []
[parse.expand]
crates = ["rustscreen"]
all_features = false
default_features = true
features = []
我在 generate_with_config().unwrap() 上失败了,错误消息是我正在尝试编译的 crate 列表,然后是一个典型的 unwrap() 堆栈,开头为:

对于每个依赖项都像这样继续,没有错误消息
