1、为BehaviorTree.CPP编写BUILD.gn进行Rom集成
- Rom集成笔者开发环境：
- wsl2+ubuntu18.04
- OpenHarmony 3.2 release 源码
- 润和大禹200开发板
2、修改build/subsystem_config.json，新增子系统behaviortree定义
在源码/build/subsystem_config.json中增加子系统behaviortree。
"behaviortree": {
"path": "third_party/behaviortree",
"name": "behaviortree"
}3、修改vendor/hihope/rk3568/config.json文件将behaviortree添加至rk3568开发板
{
"subsystem": "behaviortree",
"components": [
{
"component": "behaviortree",
"features": []
}
]
}4、在OpenHarmony标准系统源码下third_party下放置BehaviorTree.CPP源码
- BehaviorTree.CPP 源码版本为4.1.1 ：https://github.com/BehaviorTree/BehaviorTree.CPP/tree/4.1.1。
- 并且文件夹名称修改为behaviortree。
5、third_party/behaviortree目录下添加bundle.json文件
- 特别说明：ohos.build不再使用，OpenHarmony源码中全部使用bundle.json。
- bundle.json文件:
{
"name": "@ohos/behaviortree",
"description": "",
"version": "",
"license": "",
"publishAs": "",
"segment": {
"destPath": "third_party/behaviortree"

"//third_party/behaviortree:ex04_waypoints"
],
"inner_kits": [],
"test": []
}
}
}6、BehaviorTree.CPP编译gn化,在third_party/behaviortree下添加BUILD.gn脚本文件
- third_party/behaviortree/BUILD.gn配置的模块有
- so
- libbehaviortree_cpp.z.so
- libmovebase_node_dyn.z.so
- libcrossdoor_nodes_dyn.z.so
- libdummy_nodes_dyn.z.so
- .a
- liblexy_file.a
- libbt_sample_nodes.a
- 可执行文件
- 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
- 模块之间的依赖关系
- libbehaviortree_cpp.z.so依赖lexy_file.a
- libcrossdoor_nodes_dyn.z.so依赖libbehaviortree_cpp.z.so
- libmovebase_node_dyn.z.so依赖libbehaviortree_cpp.z.so
- 所有的可执行文件都依赖libbt_sample_nodes.a和libbehaviortree_cpp.z.so
- third_party/behaviortree/BUILD.gn文件如下：
import("//build/ohos.gni")

##############################################################################7、对源码进行增量编译，推送编译生成BehaviorTree.CPP的so以及可执行文件到开发板上，验证编译结果
（1）对源码进行增量编译
- 推荐使用如下命令对对源码进行增量编译，编译生成BehaviorTree.CPP的so以及可执行文件
./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- 默认编译的是32位，添加–target-cpu arm64参数编译64位
--product-name rk3568 :表示编译的产品是rk3568 (润和大禹200)
--build-target=behaviortree ：编译子系统behaviortree
以下这些都是加快编译速度的选项
--ccache --build-target=behaviortree --disable-post-build --disable-package-image --gn-args enable_notice_collection=false --gn-args load_test_config=false（2）推送编译生成BehaviorTree.CPP的so以及可执行文件到开发板上，验证编译结果
so和可执行文件在out\rk3568\behaviortree目录下：
liblexy_file.a、libbt_sample_nodes.a等静态库文件在out\rk3568\obj\third_party\behaviortree目录下。
1、通过与ohos版本匹配的hdc_std工具,将编译生成的库以及测试用的可执行文件推送到开发板system/lib (lib64)
- 推送到开发板system/lib (lib64)，是因为运行需要链接该目录下的libc++.so
- 注意，不再是用hdc_std，改成了hdc
hdc shell
mount -o remount,rw / ## 重新加载系统为可读写
chmod 777 t02_basic_ports
./t02_basic_ports
8、对源码进行增量编译全量编译，烧录固件验证编译结果。
- 如果有将编译生成BehaviorTree.CPP的so以及可执行文件打包到固件，随固件烧录到开发板的需求。推荐进行全量编译，执行 ./build.sh --product-name rk3568 --ccache ，然后编译烧录固件到开发板上即可。
- 编译烧录好固件到开发板后，so文件会在开发板system/lib(64位系统的话在system/lib64)，可执行文件会在system/bin。
- hdc shell进入开发板后，在任意目录层级下执行可执行文件都可以。
- 将编译生成BehaviorTree.CPP的so以及可执行文件打包到固件，在上文third_party/behaviortree/BUILD.gn中已经添加相关代码。
install_enable = true
install_images = [
"system",
"ramdisk",
"updater",
