## 简介<a name="section11660541593"></a>
|
|||
|
|
|
|||
|
|
C++公共基础类库为标准系统提供了一些常用的C++开发工具类，包括：
|
|||
|
|
|
|||
|
|
- 文件、路径、字符串相关操作的能力增强接口
|
|||
|
|
- 读写锁、信号量、定时器、线程增强及线程池等接口
|
|||
|
|
- 安全数据容器、数据序列化等接口
|
|||
|
|
- 各子系统的错误码相关定义
|
|||
|

|
## 约束
|
|||
|
|
|
|||
|
|
适用于标准系统。
|
|||
|
|
## 编译构建
|
|||
|
|
### 编译部件
|
|||
|
|
```
|
|||
|
|
./build.sh --product-name rk3568 --build-target c_utils
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 编译动态库
|
|||
|
|
```
|
|||
|
|
./build.sh --product-name rk3568 --build-target commonlibrary/c_utils/base:utils
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 编译Rust动态库
|
|||
|
|
```
|
|||
|
|
./build.sh --product-name rk3568 --build-target commonlibrary/c_utils/base:utils_rust
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 编译静态库
|
|||
|
|
```
|
|||
|
|
./build.sh --product-name rk3568 --build-target commonlibrary/c_utils/base:utilsbase
|
|||
|
|
```
|
|||
|
|
### 如何依赖c_utils
|
|||
|
|
1. 进入相关模块对应BUILD.gn文件
|
|||
|
|
2. 在该模块对应位置中的`external_deps`字段内添加依赖，如下：
|
|||
|
|
```gn
|
|||
|
|
|
|||
|
|
ohos_shared_library("xxxxx") {
|
|||
|
|
...
|
|||
|
|
|
|||
|
|
external_deps = [
|
|||
|
|
...
|
|||
|
|
# 动态库依赖(可选)
|
|||
|
|
"c_utils:utils",
|
|||
|
|
# 静态库依赖(可选)
|
|||
|
|
"c_utils:utilsbase",
|
|||
|
|
# Rust动态库依赖(可选)
|
|||
|
|
"c_utils:utils_rust",
|
|||
|
|
]
|
|||
|
|
|
|||
|
|
...
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
