+# libdivsufsort 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/libdivsufsort   #三方库libdivsufsort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                      #三方库简介
+  ```
+
+- 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 libdivsufsort
+  ```
+
+- 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
+  libdivsufsort/arm64-v8a   libdivsufsort/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，将编译生成的头文件和库文件拷贝到该目录下，将编译生成的动态库（动态库名字带版本号和不带版本号的都需要）拷贝到工程的libs目录下，如下图所示：
+  &nbsp;
+
+  &nbsp;![thirdparty_install_dir](pic/libdivsufsort_install_dir.png)
+
+- 在最外层（cpp目录下）CMakeLists.txt中添加如下语句
+
+  ```shell
+  #将三方库加入工程中
+  target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libdivsufsort/${OHOS_ARCH}/lib/libdivsufsort.so)
+  #将三方库的头文件加入工程中
+  target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/libdivsufsort/${OHOS_ARCH}/include)
+  ```
+
+## 测试三方库
+- 编译出可执行的文件，使用原库自带的测试用例来做测试.但本库没有测试用例，改为执行一个demo [准备三方库测试环境](../../../lycium/README.md#3ci环境准备)
+- 进入到构建目录下的example目录，运行demo（注意arm64-v8a为构建64位的目录，armeabi-v7a为构建32位的目录）。该库构建目录下的/sample文件夹里放有对应功能的二进制文件，验证该库功能：执行 ./suftest test.txt。（test.txt文件是自行准备的，内容：AGCTATAG）
+- suftest功能：计算test.txt文件包含的字节数，并且构建后缀数组，对其构建的后缀数组进行检查。
+ 执行结果如图所示：
+
+```shell
+  cd /data/tpc_c_cplusplus/thirdparty/libdivsufsort-2.0.0/libdivsufsort-2.0.0/arm64-v8a-build/example
+  ./suftest test.txt
+```
+&nbsp;![libdivsufsort_test](pic/libdivsufsort_test.png)
