Rust Windows下编译静态链接VCRuntime140.dll

Rust 编译出来的exe默认动态链接VC运行库，分发电脑上需要安装有Microsoft Visual C++ Redistributable for Visual Studio 2015运行库。

编译时能静态链接进去，就省去客户端未安装运行库的问题。方法如下:

只需在当前根目录下新建.cargo\config.toml，写入以下配置

目录结构

bash 复制代码

├── .cargo
│   └── config.toml
├── Cargo.lock
├── Cargo.toml
└── src
    └── main.rs

.cargo\config.toml

toml 复制代码

[target.'cfg(all(windows, target_env = "msvc"))']
rustflags = ["-C", "target-feature=+crt-static"]

测试代码main.rs

rust 复制代码

use windows::{core::h, Win32::UI::WindowsAndMessaging::{MessageBoxW, MB_OK}};

fn main() {
    unsafe{
        MessageBoxW(None, h!("Demo"), h!("自带vcruntime140.dll"), MB_OK);
    }
}

Cargo.toml

toml 复制代码

[package]
name = "rust_vc_runtime"
version = "0.1.0"
edition = "2021"

[dependencies.windows]
version = "0.58.0"
features = [
    "Win32_UI_WindowsAndMessaging",
    "Win32_UI_Shell"
]

添加.cargo\config.toml和未添加.cargo\config.toml结果
