когда я использую bindgen в ржавчине, мне не удалось выполнить llvm-config: Os {code: 2, kind: NotFound error
В build.rs:
extern crate bindgen;
use std::env;
use std::path::PathBuf;
use std::{process::Command, str};
fn main() {
println!("cargo:rustc-link-lib=llvm");
println!("cargo:rerun-if-changed=TransverseMercatorWrapper.hpp");
let llvm_config_out = Command::new("llvm-config")
.args(&["--cxxflags", "--ldflags", "--system-libs", "--libs", "core"])
.output()
.expect("failed to execute llvm-config");
let llvm_clang_args = llvm_config_out
.stdout
.split(|byte| byte.is_ascii_whitespace())
.map(|arg| str::from_utf8(arg).unwrap());
let bindings = bindgen::Builder::default()
.header("TransverseMercatorWrapper.hpp")
.clang_arg("-x").clang_arg("--").clang_arg("c++") // c++ flag
.clang_args(llvm_clang_args)
.parse_callbacks(Box::new(bindgen::CargoCallbacks))
.generate()
.expect("unable to generate bindings");
let out_path = PathBuf::from(env::var("OUT_DIR").unwrap());
bindings
.write_to_file(out_path.join("bindings.rs"))
.expect("couldn't write bindings!");
}
Когда я использую cargo build --realease
, У меня такие ошибки:
D:\big_test\rust\pl_qin>cargo build --release
Compiling pl_qin v1.0.0 (D:\big_test\rust\pl_qin)
error: failed to run custom build command for `pl_qin v1.0.0 (D:\big_test\rust\pl_qin)`

Кто-нибудь знает почему?
