2.0版本的编译发生了很大的变化，由hb命令，变成了build.sh。经过分析发现，build.sh也是调用各种的python脚本来进行构建。这样看来1.1.0用json写配置，用python的 hb 解析，再调用gn、ninja来执行编译构建反而更简单了。估计下个版本还会改，我估计会统一成hb命令。 所以这次先简单分析下。 ./build.sh --product-name Hi3516DV300 ```Bash -x #回显参数和命令 -v #回显执行的源码 打开 OpenHarmony\build\build_scripts 下的 build.sh、build_common.sh、build_ohos.sh、build_standard.sh、parse_params.sh 将set -e 改为 set -exv 开启调试模式 ``` ## build.sh 加了调试参数，我们来分析下 build.sh 在编译构建中做了什么。 ```Bash # 各种判断和获取参数 # preloader 一.预加载 ${PYTHON3} ${source_root_dir}/build/loader/preloader/preloader.py \ --product-name ${product_name} \ --source-root-dir ${source_root_dir} \ --products-config-dir "productdefine/common/products" \ --preloader-output-root-dir "out/build_configs" # 设置环境变量 source ${source_root_dir}/out/build_configs/${product_name}/preloader/build.prop # source /home/bright/OpenHarmony/out/build_configs/Hi3516DV300/preloader/build.prop # call build 二.编译构建 ${source_root_dir}/build/build_scripts/build_${system_type}.sh \ --product-name ${product_name} \ --device-name ${device_name} \ --target-os ${target_os} \ --target-cpu ${target_cpu} \ ${build_params} ``` ## 一.预加载 debug的方法，用单步调试来看看这个 preloader.py 的作用。  调试参数： ```json { // 使用 IntelliSense 了解相关属性。 // 悬停以查看现有属性的描述。 // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "preloader.py", "type": "python", "request": "launch", "program": "./build/loader/preloader/preloader.py", "console": "integratedTerminal", "args": [ "--product-name","Hi3516DV300", "--source-root-dir","", "--products-config-dir","productdefine/common/products", "--preloader-output-root-dir","out/build_configs" ], "stopOnEntry": true } ] } ``` 调用了2个python文件，Z:\OpenHarmony\build\loader\preloader\preloader.py 和 Z:\OpenHarmony\build\scripts\util\file_utils.py 这个函数有4个参数。 ```Bash python3 build/loader/preloader/preloader.py \ --product-name Hi3516DV300 \ --source-root-dir "" \ --products-config-dir productdefine/common/products \ --preloader-output-root-dir out/build_configs Z:\OpenHarmony\build\loader\preloader\preloader.py:180 # 建议断点打在这，跳过import parser = argparse.ArgumentParser() ``` 全部操作主要就是def _run(args):这一个函数 ```python Z:\OpenHarmony\build\loader\preloader\preloader.py:133 def _run(args): # 忽略不重要的步骤，直接看核心部分 # 生成 out/build_configs/Hi3516DV300/preloader/parts.json write_json_file(parts_info_file, parts_config_info) # 获取 OpenHarmony/build/loader/preloader/platforms.template 这个模板 platforms_template_file = _get_platform_template_file(args.source_root_dir) # 复制 OpenHarmony\out\build_configs\standard_system\platforms.build _copy_platforms_config(platforms_template_file, parts_info_file, platform_config_output_path) _build_info_list = [] build_info_file = os.path.join(product_info_output_path, 'build.prop') for k, v in build_configs.items(): _build_info_list.append('{}={}'.format(k, v)) # 生成 out/build_configs/Hi3516DV300/preloader/build.prop write_file(build_info_file, '\n'.join(_build_info_list)) ``` 简单来说就是通过产品形态配置仓调取3个json文件+1个platforms.template，生成3个配置文件 产品形态配置仓调取3个json文件，具体可以参考：https://gitee.com/openharmony/productdefine_common ```Bash 配置文件： productdefine/common ├── base # 不同系统类型的最小系统，开发者不用配置，系统提供 │ └── standard_system.json ├── device # device配置，配置文件按照device name命名 │ └── hi3516dv300.json └── products # 产品配置，配置文件按照product name命名 └── Hi3516DV300.json 输出文件： ├── Hi3516DV300 │ └── preloader │ ├── build.prop │ └── parts.json └── standard_system └── platforms.build ``` 来个更直观的对比图吧。    ## 二.编译构建 build_standard.sh 这个脚本有2个任务： 1. 准备好参数执行gn、ninja构建命令。 2. 将编译好的文件打包成镜像。 ```Bash build/build_scripts/build_standard.sh --product-name Hi3516DV300 --device-name hi3516dv300 --target-os ohos --target-cpu arm # 换个姿势，方便查看 build_standard.sh --product-name Hi3516DV300 --device-name hi3516dv300 --target-os ohos --target-cpu arm ``` 接下来先分析下 build_standard.sh ```Bash Z:\OpenHarmony\build\build_scripts\build_standard.sh # 忽略不重要的步骤，直接看核心部分 function main() { # build ohos do_make_ohos # 这个函数在 OpenHarmony\build\build_scripts\build_common.sh 文件中。 # 而最终这个函数会生成，下面这条构建脚本，主要的编译工作都是由 build_ohos.sh 来完成的。 + build/build_scripts/build_ohos.sh device_type=Hi3516DV300 target_os=ohos target_cpu=arm gn_args=is_standard_system=true ... ... #
