学习一波,之前搞过hi3861开发板的oh源码编译，不过那个是轻量系统liteos-m，看看全量编译是什么情况。

环境

  • Ubuntu 20.04虚拟机
  • 已配置gitee ssh公钥
  • sudo dpkg-reconfigure dash切换shell为bash

repo init -u git@gitee.com:openharmony/manifest.git -b master --no-repo-verify
repo sync -c
repo forall -c 'git lfs pull'

执行prebuilts：在源码根目录下执行prebuilts脚本，安装编译器以及二进制工具：

1
bash build/prebuilts_download.sh

编译源码

安装编译工具

想要详细了解OpenHarmony编译构建模块功能的开发者可参考编译构建指南。

安装hb

1
2
python3 -m pip install --user build/hb

设置环境变量，将hb加入到环境变量中
卸载命令：python3 -m pip uninstall ohos-build

编译

进入源码目录执行以下命令进行编译:

# 设置编译路径
hb set
.
# 在hihope下选择rk3568并回车
# 如果是64位系统，则需要添加命令
hb build --target-cpu arm64
# 执行编译
# 单独编译一个部件（例如hello， `hb build -T 目标名称）
hb build -T <Target_Name>
# 增量编译整个产品，可以使用`hb build`
hb build
# 完整编译整个产品，可以使用`hb build -f`
hb build -f

或者直接运行build.sh进行编译

1
./build.sh --product-name {product_name} --ccache --target-cpu arm64

编译成功如下图所示，输出结果在//out/{product_name}/目录下：

编译模块

主要有两种编译方式，命令行方式和hb方式，这里以命令行方式为例。
模块可以使用“–build-target 模块名”单独编译，模块名可以在部件目录下的bundle.json里查看sub_component字段，例如drviers_peripheral_codec部件内容中sub_component字段定义了目标名：hdf_media_codec

  }
}

编译命令如下：

1
./build.sh --build-target 模块名

也可以编译相应产品，以编译hispark_taurus_standard为例，编译命令如下：

1
./build.sh --product-name hispark_taurus_standard --build-target 模块名 --ccache

还可以编译模块所在的部件：

1
./build.sh --product-name hispark_taurus_standard --build-target musl --build-target 模块名 --ccache

编译模糊测试用例

参考: https://gitee.com/openharmony/testfwk_developer_test/blob/master/libs/fuzzlib/README_zh.md
可能需要对实际设备进行fuzz？
