概述:

本文主要描述了，如何在ubuntu-20.04操作系统上，编译RK3568平台的OpenHarmony 5.1版本。

搭建编译环境

a. 安装软件包

sudo apt-get install git-lfs ruby genext2fs build-essential git curl libncurses5-dev libncursesw5-dev openjdk-11-jdk python3 python3-pip binutils git git-lfs gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4 bc gnutls-bin python3.8 python3-pip ruby u-boot-tools mtd-utils scons default-jdk

b. 更改系统的shell环境为bash

sudo dpkg-reconfigure dash 选择no 然后保存

同步源码

mkdir RK3568_Harmony

cd RK3568_Harmony

curl https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > repo

chmod a+x repo

./repo init -u OpenHarmony/manifest -b OpenHarmony-5.1.0-Release --no-repo-verify

./repo sync -c -j16

./repo forall -c 'git lfs pull'

编译

1. 执行prebuilts

#在源码根目录下执行脚本，安装编译器及二进制工具

cd RK3568_Harmony

./build/prebuilts_download.sh

2. 执行编译

./build.sh --product-name rk3568

编译完成后，会有如下显示：

build system image successful.

=====build RK3568 successful.

生成的固件保存在out/rk3568/packages/phone/images目录下，生成的文件有
