项目路径介绍 ```text . ├── my_rust_sdk // rust sdk，生成 C 的 .a & .h 供鸿蒙静态库使用 ├── my_lib // 鸿蒙静态库，包含 C++ 代码 ├── entry // 鸿蒙 Demo └── scripts // 编译脚本，负责把 rust sdk 变成 C 语言静态库 ``` # 运行项目 ## 安装 rust nightly 版本和鸿蒙编译链 1. rust nightly 的安装和 aarch64-unknown-linux-ohos 安装 如何安装可以问 ai 2. 配置环境变量 RC_OPEN_OHOS_PATH 目的是找到鸿蒙平台的 clang 和鸿蒙平台的头文件 详细见 scripts/build-rust.sh 的实现 ## 编译 rust 项目根路径下执行 ```shell bash scripts/build-rust.sh ``` 编译成功后 可以看到 my_lib/src/main/cpp/rcim_client.h ，这是 rust 生成的 .h 文件 可以看到 my_lib/src/main/cpp/libs/arm64-v8a/librust_sdk.a ，这是 rust 生成的 .a 库 鸿蒙静态库项目 my_lib 直接依赖了 librust_sdk.a 编译好 rust 库之后，就可以直接运行 APP 项目了 # 问题 Log 分析 ##
