Linux（Zorin OS）下跨平台编译 Rust 项目

三月 14, 2024 / 技术分享

### 编译 Linux 平台
```
rustup target add x86_64-unknown-linux-musl
cargo build --release --target=x86_64-unknown-linux-musl
```
 
### 编译 Windows 平台
```
rustup target add x86_64-pc-windows-gnu
cargo build --release --target=x86_64-pc-windows-gnu
```

### 编译 macOS 平台
macOS Cross toolchain for Linux and *BSD：https://github.com/tpoechtrager/osxcross
macOS SDK：https://github.com/alexey-lysiuk/macos-sdk

编译完成后结果分别在项目根目录`target`文件夹下的`x86_64-unknown-linux-musl`和`x86_64-pc-windows-gnu`文件夹下

#### 报错及解决方法

报错1：`error occurred: Failed to find tool. Is x86_64-w64-mingw32-gcc installed?`
解决方法：`apt install gcc-mingw-w64`

报错2：`error: failed to run custom build command for openssl-sys v0.x https://docs.rs/openssl/latest/openssl/`
解决方法：在 Cargo.toml 文件中 dependencies 项下添加如下代码
```
# For Linux and macOS, we need the vendored ssl
[target.'cfg(target_os = "linux")'.dependencies]
openssl = { version = "0.10.57", features = ["vendored"] }
[target.'cfg(target_os = "macos")'.dependencies]
openssl = { version = "0.10.57", features = ["vendored"] }
```
