在Windows上使用板条箱cargo-vcpkg和magic将magic（c库）链接到cargo项目

Question

我的货运项目依赖于 vcpkg 上的 libmagic。我正在使用一个名为“cargo-vcpkg”的板条箱来管理我的 C 依赖项，并且板条箱 magic 提供了该库的绑定。
我使用的是最新版本的 Windows 11 64 位

我在 Cargo.toml 中的依赖项如下所示 -

[package]
...

[dependencies]
magic = "0.13.0"
...

[package.metadata.vcpkg]
git = "https://github.com/microsoft/vcpkg"
rev = "master"
dependencies = ["libmagic:x64-windows-static"]

我已经运行

cargo vcpkg build

将 deps 编译为 dll 文件。 但是，尝试使用

cargo build

或

cargo run

构建我的项目时，出现以下错误 -

error: linking with `link.exe` failed: exit code: 1181

这表明文件 magic.lib 不存在。

我的文件夹树如下所示 -
项目目录

• 来源/
• ...
• vcpkg/
  • bin/已安装/x64-windows-static/lib/magic.lib
• 货物.toml

我尝试过以下方法 -

• 清洁并重新运行

  cargo vcpkg build

• 在 vcpkg 目录中手动运行

  vcpkg integrate install

• 使用不同的魔法绑定箱，称为

  magic-sys

• 从 Visual Studio 2019 安装程序重新安装 C++ 构建工具

Answer 1

大多数 Rust 绑定库都有自己的构建命令，只需指定它们即可自动应用于链接。

magic 库在内部使用 magic-sys 进行构建后链接。如果需要指定版本，可以使用 magic-sys 中的功能进行修改。

如果需要静态构建，则需要克隆 magic 和 magic-sys 存储库，在本地修改它们，并使用 path = "../path" 指定它们。
