背景

OHOS的编译构建系统是由sh脚本（或bat脚本），python脚本，Gn和Ninja工具组成的编译构建框架。总体编译构建流程是根据产品配置，生成具体依赖关系，然后使用Gn配置构建目标，通过Gn生成ninja文件，然后执行ninja生成二进制，最后打包生成镜像的过程。本篇主要涉及配置文件规则和编译初期的规则检查。

简单解读（基本规则）

编译构建的重要组成部分：
OHOS的编译构建以下三个仓是编译构建重要的三个仓：

productdefine：产品配置仓，包含了基础部件的组成形态，主要看/produdctdefine/common/base目录下的文件。
vendor：各厂家的产品仓，如大家最熟悉的/vendor/hihope/rk3568，编译命令指定–product-name来寻找对应的产品。
build：编译构建仓，包括规范，检查工具，编译构建脚本等等，OHOS编译构建的核心仓

关注重点

BUILD.gn：每个模块都对应一个BUILD.gn文件。可以使用提供的模板，也可以使用gn语法规则自定义编写。

例子：

ohos_shared_library示例：

```
import("//build/ohos.gni")
ohos_shared_library("helloworld") {
  sources = []
  include_dirs = []
  cflags = []
  cflags_c = []
  cflags_cc = []
  ldflags = []
  configs = []
  deps =[]  # 部件内模块依赖

  # 跨部件模块依赖定义，
  # 定义格式为 "部件名:模块名称"
  # 这里依赖的模块必须是依赖的部件声明在inner_kits中的模块
  external_deps = [
    "part_name:module_name",
  ]

  output_name = ""           # 可选，模块输出名
  output_extension = ""      # 可选，模块名后缀
  module_install_dir = ""    # 可选，缺省在/system/lib64或/system/lib下， 模块安装路径，模块安装路径，从system/，vendor/后开始指定
  relative_install_dir = ""  # 可选，模块安装相对路径，相对于/system/lib64或/system/lib；如果有module_install_dir配置时，该配置不生效
  install_images = []        # 可选，缺省值system，指定模块安装到那个分区镜像中，可以指定多个

  part_name = "" # 必选，所属部件名称
}
```

ohos_executable示例：

ohos_executable模板属性和ohos_shared_library基本一致。

注意：可执行模块（即ohos_executable模板定义的）默认是不安装的，如果要安装，需要指定install_enable = true。

ohos_prebuilt_etc示例：

```
import("//build/ohos.gni")
ohos_prebuilt_etc("etc_file") {
  source = "file"
  deps = []                 # 部件内模块依赖
  module_install_dir = ""   #可选，模块安装路径，从system/，vendor/后开始指定
  relative_install_dir = "" #可选，模块安装相对路径，相对于system/etc；如果有module_install_dir配置时，该配置不生效
  install_images = []       # 可选，缺省值system，指定模块安装到那个分区镜像中，可以指定多个
  part_name = ""            # 必选，所属部件名称
}
```

更多详细的模板信息请参照模块配置规则。

bundle.json：定义了子系统包含的部件。每个部件定义它所包含的模块目标component.build.sub_component，以及部件间交互的接口component.build.inner_kits，测试用例component.build.test_list。部件包含的模块目标component.build.sub_component是必须要说明的。原来老版本有ohos.build，后面全部整改为bundle.json。

       "test": []                                # 部件测试用例编译入口
     }
  }
}

新增部件的大致步骤就是在在部件目录中新建一个bundle.json，然后再在//vendor/{product_company}/{product-name}/config.json中添加对应的部件，直接添加到原有部件后即可。具体流程请参照编译构建指导的配置规则与新增并编译不同配置，其中详细的介绍了如何添加一个模块、部件或者子系统。

vendor里的config.json：指明了产品名，产品厂商，产品设备，版本，要编译的系统类型，以及产品包含的子系统。

{
  "product_name": "MyProduct",
  "version": "3.0",
  "type": "standard",
  "target_cpu": "arm",
  "ohos_version": "OpenHarmony 1.0",
  "device_company": "MyProductVendor",
  "board": "MySOC",
  "enable_ramdisk": true,
  "subsystems": [
  {
    "subsystem": "ace",
    "components": [
      { "component": "ace_engine_lite", "features":[""] }
    ]
  }，

  ]
}

常见Q&A解读（错误处理）

常见七类问题：

subsystem_components

错误原因：

子系统配置清单中的子系统名和部件配置清单中的子系统名不一致；或bundle.json中的部件名和部件配置清单中的部件名不一致

Warning: find subsystem startup_ext failed, please check it in /home/XXX/workspace/system_single_frame/system_component/out/products_ext/vendor/xxx/XXX/config.json.
或
Exception: find subsystem startup_ext failed, please check it in /home/XXX/workspace/system_single_frame/system_component/out/products_ext/vendor/xxx/XXX/config.json.
Warning: find component hiview_plugins_xxx failed, please check it in /home/XXX/workspace/system_single_frame/system_component/out/products_ext/vendor/xxx/XXX/config.json.
或
Exception: find component hiview_plugins failed, please check it in /home/XXX/workspace/system_single_frame/system_component/out/products_ext/vendor/xxx/XXX/config.json.

解读：

“subsystem” 代表产品部件列表（config.json）配置的子系统名错误。

“component”代表产品部件列表（config.json）配置的部件名错误。

此类问题代表vendor\xxx\build\component_config\system\XXX\part_config.json 文件中配置的子系统名或者部件名错误，component 代表部件名配置错误， subsystem 代表子系统名配置错误。

整改方法：

如果是子系统名配置错误，请排查 part_config.json中配置的子系统名是否在subsystem_config.json中有配置

OHOS的subsystem_config.json路径：build/subsystem_config.json。

如果是部件名配置错误，请排查part_config.json文件中的部件名是否和该部件的bundle.json中的部件名配置一致。

bundle_subsystem_error

错误原因：

bundle.json中定义的子系统名和子系统配置清单中的不一致

具体日志

warning: subsystem name config incorrect in '/home/XXX/workspace/system_single_frame/system_component/foundation/ability/ability_base/bundle.json', build file subsystem name is ability, configured subsystem name is aafwk.
或
Exception: subsystem name config incorrect in '/home/XXX/workspace/system_single_frame/system_component/foundation/ability/ability_base/bundle.json', build file subsystem name is ability, configured subsystem name is aafwk.

解读：

该问题代表bundle.json里的子系统名称配置和subsystem_config.json配置不一致，需要整改bundle.json的子系统名称。

bundle.json路径：foundation/ability/ability_base/bundle.json。

整改方法：

请检查本部件bundle.json中是否有配置子系统并且配置的子系统名与subsystem_config.json中一致，若不一致，请将bundle.json中的子系统名改为subsystem_config.json中的子系统名。

gn_part_or_subsystem_error。

错误原因：

BUILD.gn中定义的部件名或子系统名与bundle.json中定义的不一致。

具体日志：

[OHOS INFO] warning: subsystem name or part name is incorrect, target is //foundation/distributedhardware/distributed_audio/hdf_service/distributed_audio/hdi_service/audio/v1_0:libaudio_manager_daudio_primary_service_1.0, subsystem name is hdf, part name is drivers_peripheral_distributed_audio
或
Exception: subsystem name or part name is incorrect, target is //foundation/distributedhardware/distributed_audio/hdf_service/distributed_audio/hdi_service/audio/v1_0:libaudio_manager_daudio_primary_service_1.0, subsystem name is hdf, part name is drivers_peripheral_distributed_audio

解读：

该问题代表模块的BUILD.gn里面配置的子系统名或者部件名不准确，需要和部件bundle.json对齐

BUILD.gn路径：foundation/distributedhardware/distributed_audio/hdf_service/distributed_audio/hdi_service/audio/v1_0/BUILD.gn。

编译目标：libaudio_manager_daudio_primary_service_1.0

整改方法：

将本部件下该模块BUILD.gn中的部件名与子系统名改为本部件bundle.json中的子系统名和部件名

如果已确认BUILD.gn和bundle.json中的子系统名和部件名一致，请再确认part_config.json中是否正确配置了该子系统名和部件名

part_config.json路径：（和编译命令中abi-type、device-type参数一致）

系统组件:

vendor/xxx/build/component_config/system/XXX/part_config.json

芯片组件：

vendor/xxx/build/component_config/chipset/XXX/part_config.json

deps_added_external_part_module

错误原因：

BUILD.gn中使用deps依赖了外部部件的模块

具体日志：

[OHOS INFO] WARNING:deps validation part_name: 'distributed_camera', target: '//foundation/distributedhardware/distributed_camera/services/channel:distributed_camera_channel', dep: '//foundation/distributedhardware/distributed_hardware_fwk/interfaces/inner_kits:libdhfwk_sdk' failed!!

解读：

该问题代表该模块通过deps依赖了部件外的模块，应该用external_deps依赖。

BUILD.gn路径：foundation/distributedhardware/distributed_camera/services/channel/BUILD.gn。

编译目标：distributed_camera_channel。

deps中依赖的外部模块：foundation/distributedhardware/distributed_hardware_fwk/interfaces/inner_kits:libdhfwk_sdk。

整改方法：

将该模块从deps转移到external_deps中。

注：deps中使用的是"路径:模块名"，而改到external_deps中是使用 “部件名:模块名” 的方式。

external_deps_added_self_part_module

错误原因：

使用external_deps依赖了本部件的模块。

具体日志：

[OHOS INFO] WARNING: preferences in target //foundation/distributeddatamgr/preferences/frameworks/js/napi/preferences:preferences is dependency within part preferences, Need to used deps
或
Exception: preferences in target //foundation/distributeddatamgr/preferences/frameworks/js/napi/preferences:preferences is dependency within part preferences, Need to used deps

解读：

该日志代表该模块通过external_deps依赖了本部件模块，需要改成deps依赖

BUILD.gn路径：foundation/distributeddatamgr/preferences/frameworks/js/napi/preferences

external_deps中依赖的本部件：preferences

整改方法：

将该依赖从external_deps转移到deps中

external_deps_bundle_not_add

**错误原因：**BUILD.gn中外部依赖了其他部件的模块，但是bundle.json中没有添加这个部件

注：对于三方部件，如果BUILD.gn里面用的是deps依赖，那在bundle.json中需要加到third_party中，如果使用的是external_deps依赖的三方部件，那在bundle.json中需要加到components中

具体日志：

[OHOS INFO] WARNING: //base/theme/wallpaper_mgr/frameworks/kits/extension:wallpaperextension depend part window_manager, need set part deps info to /home/XXX/workspace/system_single_frame/system_component/base/theme/wallpaper_mgr/bundle.json.
或
Exception: //base/theme/wallpaper_mgr/frameworks/kits/extension:wallpaperextension depend part window_manager, need set part deps info to /home/XXX/workspace/system_single_frame/system_component/base/theme/wallpaper_mgr/bundle.json.

解读：

该日志代表该模块（BUILD.gn）里面依赖的外部部件，但没有在部件bundle.json声明，需要在bundle.json声明。

BUILD.gn路径：base/theme/wallpaper_mgr/frameworks/kits/extension/BUILD.gn
编译目标：wallpaperextension
依赖的部件：window_manager
bundle.json路径：base/theme/wallpaper_mgr/bundle.json.

整改方法：

将被依赖的外部部件添加到bundle.json中的deps:components字段中，如上述例子中，需要将”input”和”window_manager”添加到bundle.json中

third_deps_bundle_not_add

错误原因：

BUILD.gn中依赖了三方部件，但是部件bundle.json中没有添加该三方部件

具体日志：

[OHOS INFO] WARNING: //base/security/device_auth/services:deviceauth_service depend part //third_party/cJSON:cjson, need set part deps cjson info to /home/XXX/workspace/chipset_single_frame/vendor_baltimore_musl/base/security/device_auth/bundle.json.

该日志代表该模块（BUILD.gn）里面依赖的三方部件，没有在部件bundle.json中的third_party中声明，需要在bundle.json声明。

BUILD.gn路径：base/security/device_auth/services
编译目标：deviceauth_service
依赖的三方部件：cjson
bundle.json路径：vendor_baltimore_musl/base/security/device_auth/bundle.json

整改方法：

将被依赖的三方部件添加到bundle.json中的deps:third_party字段中，如上述例子中，需要将 “cjson” 添加到bundle.json中。
