+# fft2d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/fft2d      #三方库fft2d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
+    ├── OAT.xml                           #扫描结果文件
+    ├── 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
+    ├── fft2d_pkg.patch                   #用于fft2d库编译的补丁
+    ```
+
+*   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 fft2d
+    ```
+
+*   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
+    fft2d/arm64-v8a-build   fft2d/armeabi-v7a-build
+    ```
+
+*   [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拷贝到该目录下，将编译生成的三方库拷贝到工程的libs目录下，如下图所示：
+
+&nbsp;![thirdparty_install_dir](pic/libfft2d-dev.png)
+
+- 在最外层（cpp目录下）CMakeLists.txt中添加如下语句
+
+  ```cmake
+    #将三方库加入工程中
+    target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/liballoc.so)
+    target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libfftsg2d.so)
+    target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libfftsg3d.so)
+    target_link_libraries(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/../../../libs/${OHOS_ARCH}/libshrtdct.so)
+
+    #将三方库的头文件加入工程中
+    target_include_directories(entry PRIVATE ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/fft2d/${OHOS_ARCH}/include)
+  ```
+  
+
+## 测试三方库
+
+- 编译出可执行的文件进行测试，[准备三方库测试环境](../../../lycium/README.md#3ci环境准备)
+
+- 如图所示，进入到构建目录运行测试用例（注意arm64-v8a-build为构建64位的目录，armeabi-v7a-build为构建32位的目录）
