+# ytnef集成到应用hap
+
+本库是在RK3568开发板上基于OpenHarmony3.2 Release版本的镜像验证的，如果是从未使用过RK3568，可以先查看[润和RK3568开发板标准系统快速上手](https://gitee.com/openharmony-sig/knowledge_demo_temp/tree/master/docs/rk3568_helloworld)。
+
+## 开发环境
+
+- [开发环境准备](../../../docs/hap_integrate_environment.md)
+
+## 编译三方库
+
+- 下载本仓库
+
+  ```shell
+  git clone https://gitee.com/openharmony-sig/tpc_c_cplusplus.git --depth=1
+  ```
+
+- 三方库目录结构
+
+  ```shell
+  tpc_c_cplusplus/thirdparty/ytnef            #三方库ytnef的目录结构如下
+  ├── docs                                    #三方库相关文档的文件夹
+  ├── HPKBUILD                                #构建脚本
+  ├── HPKCHECK                                #测试脚本
+  ├── SHA512SUM                               #三方库校验文件
+  ├── README.OpenSource                       #说明三方库源码的下载地址，版本、license等信息
+  ├── README_zh.md   
+  ```
+  
+- 在lycium目录下编译三方库
+
+  编译环境的搭建参考[准备三方库构建环境](../../../lycium/README.md#1编译环境准备)
+
+  ```shell
+  cd lycium
+  ./build.sh ytnef
+  ```
+
+- 三方库头文件及生成的库
+
+  在lycium目录下会生成usr目录，该目录下存在已编译完成的32位和64位三方库
+
+  ```shell
+  ytnef/arm64-v8a   ytnef/armeabi-v7a
+  ```
+  
+- [测试三方库](#测试三方库)
+
+## 应用中使用三方库
+
+- 在IDE的cpp目录下新增thirdparty目录，将编译生成的库拷贝到该目录下，如下图所示
+
+  ![thirdparty_install_dir](pic/ytnef_usage_for_ide.png)
+
+- 在最外层（cpp目录下）CMakeLists.txt中添加如下语句
+
+  ```cmake
+  #将三方库的头文件加入工程中
+  target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/ytnef/${OHOS_ARCH}/include)
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/ytnef/${OHOS_ARCH}/lib/libytnef.a)
+  ```
+
+
+## 测试三方库
+
+三方库的测试使用原库自带的测试用例来做测试，[准备三方库测试环境](../../../lycium/README.md#3ci环境准备)
+
+进入到对应版本目录的test-data子目录,执行如下命令./test.sh 
+
