在 Windows 10 上使用 MinGW 和 MSYS2 编译 mongodb 驱动程序时出现问题

Question

我正在编译一个使用mongodb驱动程序的项目。现在程序无法编译，因为在包依赖项中，需要引用两个库ring_core_0_17_8_fiat_curve25519_adx_mul和另一个库ring_core_0_17_8_fiat_curve25519_adx_square。这是使用 MSYS2 中的 gcc/x86_64-w64-mingw32/14.2.0 在 Windows 10 上编译的。

task_process.rs

mod queues_mongo;

use queues_mongo::email_queue::search_queue;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
  let _ = search_queue().await;

  Ok(())
}

email_queue.rs

extern crate dotenv;

use dotenv::dotenv;
use std::env;

use mongodb::{
 bson::{doc, Document},
 error, Client, Collection, Database,
};

#[allow(dead_code)]
pub async fn search_queue() -> error::Result<()> {
 dotenv().ok();

 let uri: String = env::var("MONGO_URI").expect("MONGO_URI");
 let db: String = env::var("MONGO_DATABASE").expect("MONGO_DATABASE");

 let client: Client = Client::with_uri_str(uri).await?;
 let database: Database = client.database(db.as_str());
 let collection: Collection = database.collection("emails");
 let email: Option = collection.find_one(doc! { "status": "Sent" }).await?;

 println!("Found a email:\n{:#?}", email);

 Ok(())
}

完全错误

这几天我一直在努力并找到了解决方案：

1. 克隆项目或将其复制到 MSYS2 中的“C:\msys64\home\my_user”，不要在 Windows 用户文件夹“C:\Users\My User”中执行此操作，因为 Rust 编译器会依赖项有问题。

2. 使用 “build.rs”预编译库 “ring_core_0_17_8_fiat_curve25519_adx_mul” 和库 “ring_core_0_17_8_fiat_curve25519_adx_square”。

示例：

fn main() -> Result<(), Box<dyn std::error::Error>> {
  let build_lib_path: &str =
    r"C:\msys64\home\My User\projects\rustlang-course\target\debug\build_lib";

  let includes: [&str; 2] = [
    r"C:\Users\My User\.cargo\registry\src\index.crates.io-6f17d22bba15001f\ring-0.17.8\pregenerated\tmp",
    r"C:\Users\My User\.cargo\registry\src\index.crates.io-6f17d22bba15001f\ring-0.17.8\include",
  ];

  cc::Build::new()
    .file(r"C:\Users\My User\.cargo\registry\src\index.crates.io-6f17d22bba15001f\ring-0.17.8\third_party\fiat\asm\fiat_curve25519_adx_mul.S")
    .includes(&includes)
    .out_dir(&build_lib_path)
    .compile("ring_core_0_17_8_fiat_curve25519_adx_mul");

  cc::Build::new()
    .file(r"C:\Users\My User\.cargo\registry\src\index.crates.io-6f17d22bba15001f\ring-0.17.8\third_party\fiat\asm\fiat_curve25519_adx_square.S")
    .includes(&includes)
    .out_dir(&build_lib_path)
    .compile("ring_core_0_17_8_fiat_curve25519_adx_square");

  println!("cargo::rustc-link-lib=static=ring_core_0_17_8_fiat_curve25519_adx_mul");
  println!("cargo::rustc-link-lib=static=ring_core_0_17_8_fiat_curve25519_adx_square");
  println!("cargo::rustc-link-search=native={}", build_lib_path);

  Ok(())
}

您还必须在 C:\Users\My User.carg 中进行此调整
