OpenHarmony 4.0 Release 编译及报错

1、环境准备

安装下面这三东西，是为了下载 Harmony 源码

sudo apt install curl

sudo apt install python3-pip

sudo apt install git-lfs

安装下面这五个东西，是为了解决编译到最后报错(头铁不信的，你可以试试，等最后再安装)

sudo apt install default-jdk

sudo apt install mtd-utils

sudo apt install scons

sudo apt install gcc-arm-none-eabi

sudo apt install gcc-arm-linux-gnueabi

sudo apt-get install libxt-dev

sudo apt-get install libx11-dev

sudo apt install xorg-dev

sudo apt-get install liblz4-tool

sudo apt install dwarves

2、安装 repo

务必按照此步骤安装repo。ubuntu默认提供的repo每次启动都会访问googlge服务器，会被墙。

此外20.04下需要root身份执行--否则提示没权限。

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

chmod a+x /usr/local/bin/repo

pip3 install -i Simple index requests

3、下载源码

[官网版本更新说明}(docs: OpenHarmony documentation | OpenHarmony开发者文档 - Gitee.com)

目前最新为 4.0 版本，内核基于 5.10，老版本 2.x 1.x 已经停止维护，内核基于 4.19

参考官网下载方式

repo init -u OpenHarmony/manifest -b OpenHarmony-4.0-Release --no-repo-verify

repo sync -c

repo forall -c 'git lfs pull'

注意那个 4.0 之前没有 v，以前的版本是有这个 v 的，不然会初始化失败，还有就是注意检查电脑是否断网了

4、下载编译依赖工具包

源码下载完成后，进入根目录执行 bash build/prebuilts_download.sh

看你网速快慢，我这大概10分钟，下载完成后会多出 openharmony_prebuilts 文件夹

5、编译源码

./build.sh --product-name rk3568 --ccache

第一次编译前面阶段 2W 多个文件，后面阶段 6W 多个文件，整体时间看你电脑性能。

编译中间要是出错看提示就行，少啥就自行安装，比如这种

default-jdk is not installed. please install it.

mtd-utils is not installed. please install it.

scons is not installed. please install it.

gcc-arm-none-eabi is not installed. please install it.

gcc-arm-linux-gnueabi is not installed. please install it.

Missing dependencies, please check!
