移植BehaviorTree.CPP到OpenHarmony標準系統之一

作者：離北況歸 2023-06-27 15:12:46

本篇將分享兩種移植方式，為 BehaviorTree.CPP 編寫BUILD.gn 進行Rom集成，移植后編譯出來的so和可執行文件打包進入固件的方法，移植相關的文件ohos.build修改為bundle.json，ohos.build不再使用。

想了解更多關于開源的內容，請訪問：

51CTO 開源基礎軟件社區

1、為BehaviorTree.CPP編寫BUILD.gn進行Rom集成

Rom集成筆者開發環境：

wsl2+ubuntu18.04
OpenHarmony 3.2 release 源碼
潤和大禹200開發板

2、修改build/subsystem_config.json，新增子系統behaviortree定義

在源碼/build/subsystem_config.json中增加子系統behaviortree。

"behaviortree": {
    "path": "third_party/behaviortree",
    "name": "behaviortree"
  }

3、修改vendor/hihope/rk3568/config.json文件將behaviortree添加至rk3568開發板

{
      "subsystem": "behaviortree",
      "components": [
        {
          "component": "behaviortree",
          "features": []
        }
      ]
    }

4、在OpenHarmony標準系統源碼下third_party下放置BehaviorTree.CPP源碼

BehaviorTree.CPP 源碼版本為4.1.1 ：https://github.com/BehaviorTree/BehaviorTree.CPP/tree/4.1.1。
并且文件夾名稱修改為behaviortree。

5、third_party/behaviortree目錄下添加bundle.json文件

特別說明：ohos.build不再使用，OpenHarmony源碼中全部使用bundle.json。
bundle.json文件:

{
  "name": "@ohos/behaviortree",
  "description": "",
  "version": "",
  "license": "",
  "publishAs": "",
  "segment": {
      "destPath": "third_party/behaviortree"
  },
  "dirs": {},
  "scripts": {},
  "readmePath": {
  },
  "component": {
      "name": "behaviortree",
      "subsystem": "behaviortree",
      "syscap": [],
      "features": [],
      "adapted_system_type": [],
      "rom": "",
      "ram": "",
      "deps": {
          "components": [],
          "third_party": []
      },
      "build": {
          "sub_component": [
            "http://third_party/behaviortree:lexy_file",
            "http://third_party/behaviortree:bt_sample_nodes",
            "http://third_party/behaviortree:behaviortree_cpp",
            "http://third_party/behaviortree:dummy_nodes_dyn",
            "http://third_party/behaviortree:crossdoor_nodes_dyn",
            "http://third_party/behaviortree:movebase_node_dyn",
            "http://third_party/behaviortree:t01_build_your_first_tree",
            "http://third_party/behaviortree:t02_basic_ports",
            "http://third_party/behaviortree:t03_generic_ports",
            "http://third_party/behaviortree:t05_crossdoor",
            "http://third_party/behaviortree:t04_reactive_sequence",
            "http://third_party/behaviortree:t06_subtree_port_remapping",
            "http://third_party/behaviortree:t07_load_multiple_xml",
            "http://third_party/behaviortree:t08_additional_node_args",
            "http://third_party/behaviortree:t09_scripting",
            "http://third_party/behaviortree:t10_observer",
            "http://third_party/behaviortree:t11_replace_rules",
            "http://third_party/behaviortree:ex01_wrap_legacy",
            "http://third_party/behaviortree:ex02_runtime_ports",
            "http://third_party/behaviortree:ex03_ncurses_manual_selector",
            "http://third_party/behaviortree:ex04_waypoints"
          ],
          "inner_kits": [],
          "test": []
      }
  }
}

6、BehaviorTree.CPP編譯gn化,在third_party/behaviortree下添加BUILD.gn腳本文件

third_party/behaviortree/BUILD.gn配置的模塊有

libbehaviortree_cpp.z.so
libmovebase_node_dyn.z.so
libcrossdoor_nodes_dyn.z.so
libdummy_nodes_dyn.z.so

liblexy_file.a
libbt_sample_nodes.a

可執行文件

t01_build_your_first_tree
t02_basic_ports
t03_generic_ports
t04_reactive_sequence
t05_crossdoor
t06_subtree_port_remapping
t07_load_multiple_xml
t08_additional_node_args
t09_scripting
t10_observer
t11_replace_rules
ex01_wrap_legacy
ex02_runtime_ports
ex03_ncurses_manual_selector
ex04_waypoints

模塊之間的依賴關系

libbehaviortree_cpp.z.so依賴lexy_file.a
libcrossdoor_nodes_dyn.z.so依賴libbehaviortree_cpp.z.so
libmovebase_node_dyn.z.so依賴libbehaviortree_cpp.z.so
所有的可執行文件都依賴libbt_sample_nodes.a和libbehaviortree_cpp.z.so

third_party/behaviortree/BUILD.gn文件如下：

7、對源碼進行增量編譯，推送編譯生成BehaviorTree.CPP的so以及可執行文件到開發板上，驗證編譯結果

（1）對源碼進行增量編譯

推薦使用如下命令對對源碼進行增量編譯，編譯生成BehaviorTree.CPP的so以及可執行文件

./build.sh --product-name rk3568 --ccache --build-target=behaviortree --disable-post-build --disable-package-image --gn-args enable_notice_collection=false --gn-args load_test_config=false

默認編譯的是32位，添加–target-cpu arm64參數編譯64位

--product-name rk3568 :表示編譯的產品是rk3568 (潤和大禹200)
--build-target=behaviortree ：編譯子系統behaviortree

以下這些都是加快編譯速度的選項
--ccache --build-target=behaviortree --disable-post-build --disable-package-image --gn-args enable_notice_collection=false --gn-args load_test_config=false

（2）推送編譯生成BehaviorTree.CPP的so以及可執行文件到開發板上，驗證編譯結果

so和可執行文件在out\rk3568\behaviortree目錄下：

liblexy_file.a、libbt_sample_nodes.a等靜態庫文件在out\rk3568\obj\third_party\behaviortree目錄下。

1、通過與ohos版本匹配的hdc_std工具,將編譯生成的庫以及測試用的可執行文件推送到開發板system/lib (lib64)

推送到開發板system/lib (lib64)，是因為運行需要鏈接該目錄下的libc++.so
注意，不再是用hdc_std，改成了hdc

hdc shell               
mount -o remount,rw /	    ## 重新加載系統為可讀寫
chmod 777 t02_basic_ports
./t02_basic_ports

8、對源碼進行增量編譯全量編譯，燒錄固件驗證編譯結果。

如果有將編譯生成BehaviorTree.CPP的so以及可執行文件打包到固件，隨固件燒錄到開發板的需求。推薦進行全量編譯，執行 ./build.sh --product-name rk3568 --ccache ，然后編譯燒錄固件到開發板上即可。
編譯燒錄好固件到開發板后，so文件會在開發板system/lib(64位系統的話在system/lib64)，可執行文件會在system/bin。
hdc shell進入開發板后，在任意目錄層級下執行可執行文件都可以。

將編譯生成BehaviorTree.CPP的so以及可執行文件打包到固件，在上文third_party/behaviortree/BUILD.gn中已經添加相關代碼。
