openharmony_3.1 使用第三方so文件

1、项目目录

├── build
│   ├── BUILD.gn
│   └── libbehaviortree.so //第三方so文件
├── BUILD.gn
├── bundle.json
├── include
│   ├── impl_utils.h
│   ├── single_instance.h
│   ├── task_behavior.h
│   ├── task_executor.h
│   ├── task.h
│   └── util.h
└── src
    ├── task.cpp
    ├── task_executor.cpp
    └── task_test.cpp

2、动态库编译配置

• 动态库路径 build/libbehaviortree.so

• 动态库配置build/BUILD.gn

  import("//build/ohos.gni")
  
  ohos_prebuilt_shared_library("behavior_tree_lib") {
    source = "./libbehaviortree.so"
    install_enable = true
    subsystem_name = "applications"
    part_name = "task_thread"
  }
  

3、使用动态库

• 动态库调用配置 BUILD.gn

import("//build/ohos.gni")
config("task_thread_config") {
  cflags_cc = [ 
    "-frtti",
    "-fexceptions",
  ]
}
ohos_executable("task_thread") {
  sources = [
    "src/task_test.cpp",
    "src/task_executor.cpp",
    "src/task.cpp",
   ]
  configs = [":task_thread_config"]

  include_dirs = [
    "include",
    "//third_party/BehaviorTree.CPP/include"
  ]
  deps = ["//applications/task/build:behavior_tree_lib"]
 
  part_name = "task_thread"
  subsystem_name = "applications"
}

• bundle.json配置

{
    "name": "@ohos/task_thread",
    "description": "The repository contains the Abseil C++ library code. Abseil is an open-source collection of C++ code (compliant to C++11) designed to augment the C++ standard library.",
    "version": "3.1",
    "license": "Apache V2",
    "publishAs": "code-segment",
    "segment": {
        "destPath": "applications/task"
    },
    "dirs": {},
    "scripts": {},
    "component": {
        "name": "task_thread",
        "subsystem": "applications",
        "syscap": [],
        "features": [],
        "adapted_system_type": [],
        "rom": "",
        "ram": "",
        "deps": {
            "components": [
            ],
            "third_party": []
        },
        "build": {
            "sub_component": [
                "//applications/task:task_thread",
                "//applications/task/build:behavior_tree_lib"
            ],
            "inner_kits": [
                    
            ],
            "test": []
        }
    }
}

4、编译可执行程序

./build.sh --product-name rk3568 --ccache --build-target task_thread

5、测试结果

• 修改系统目录权限，使目录可读可写 mount -o remount,rw /
• 发送编译程序和so动态库到开发板 hdc_std file send libbehaviortree.so /data
• 拷贝so到 /lib/目录mv /data/libbehaviortree.so /lib/
• 运行结果
