OpenHarmony4.0系列（一）编译环境搭建+代码上库_openharmony ubuntu编译

前期准备

1. VMware + Ubuntu20.04 + 内存8G+ + 硬盘150G+
2. Ubuntu20.04 Server + 内存64G + 硬盘24T
3. Ubuntu20.04 + 内存16G+ + 硬盘1T
4. Windows 10 通过子系统方式安装Ubuntu20.04
四种方案，推荐方案四。

20240116更新：  
1. 更加了解Docker容器后，优化部分流程，使其更加精简
2. 更改Docker使用权限，添加代码管理方案
3. 使开发者继续沿用之前Git服务器拉取代码、提交方式,Grrit代码管理保持不变

sudo usermod -aG docker $USER

git clone ssh://192.168.xx.xxx:xxxxxx/openharmony-r4.0.git 
cp -r ~/openharmony-r4.0/.git ~/openharmony/4.0

sudo chown -R user:group ~/openharmony/4.0

git add .  
// 哈哈哈,机智如我,既然解决不掉老Gerrit 版本lfs安装失败问题,就不用lfs得了.还是得多换角度思考.
// 虽然牺牲了点效率,但总比几天问题没解决强,待把Gerrit熟悉了直接升级,现阶段还是别动前人的配置

2.5 重新git clone编译通过

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

三、遇到问题汇总

3.1 系统启动盘制作问题

问题现象：U盘启动时报错error：file ‘/casper/vmlinuz’ file not found，但镜像目录文件下确有’/casper/vmlinuz’文件。
根本原因：U盘制作镜像问题，引导识别不到文件
解决方式：Rufus需以管理员权限打开，重新制作启动盘安装正常。

3.2 服务器编译遇到问题

服务器安装环境出现较多依赖问题在于与默认Android编译环境部分冲突，最终未解决，更换Docker方式。

3.2.1 repo导出文件都在根目录。。。

原因分析：由于之前配置过repo环境，默认repo总是初始化到根目录
解决方式：rm -rf /home/xxx/.repo

3.2.2

原因分析：服务器硬件为amd64架构的，报错为arm64，调用错误，删除其他架构环境。
解决方式：

dpkg --print-architecture           // amd64
dpkg --print-foreign-architectures  // arm64
sudo dpkg --remove-architecture arm64
sudo apt-get update

3.2.3

Note, selecting 'python3-distutils' instead of 'python3.8-distutils'
Note, selecting 'lib32z1-dev' instead of 'lib32z-dev'
E: Unable to locate package libc6-dev-amd64

原因分析：服务器编译环境之前是基于Android系统，部分依赖包不兼容。
解决方式：

sudo apt-get install python3-distutils lib32z1-dev libc6-dev

卸载存在问题的软件：

sudo apt-get remove --purge xxx
1

强制安装：

sudo apt-get install -f xxx

3.2.4 fatal error: ‘X11/Xcursor/Xcursor.h’ file not found

解决方案:

sudo apt-get install xorg-dev
1

3.2.5 undefined symbol: __aarch64_cas4_acq_rel,Code:4000

问题未解决，查阅资料最终方式都换成docker方式安装。

原因分析：
git config core.autocrlf 配置策略 git对换行符转换,保持当前现状

3.3.2 Gerrrit缺少LFS包支持

问题现象：

Remote "origin" does not support the LFS locking API. Consider disabling it with:
    $ git config lfs.https://192.168.xx.xxx/openharmony-r4.0.git/info/lfs.locksverify false
batch request: fatal: Gerrit Code Review: git-lfs-authenticate: not found: exit status 1

原因分析：Gerrit需安装对应plugin-lfs-bazel-stable-2.13插件以支持lfs
(此处需安装与相近版本,笔者版本为Gerrit Code Review (2.13.4))

方式一：下载对应plugin-lfs-bazel-stable-2.16包

安装插件失败,plugins下不显示,All-Project无 lfs 使能配置显示。

方案二：下载对应plugin-lfs-bazel-stable-2.13包

网上找资料查阅 无果,放弃

方案三：升级Gerrit服务器版本

未进行：前人搭的环境,若未精通,不想轻易更改,毕竟还有其他部门也在使用,没想到我也开始退而求其次了。

四、 服务器Docker管理

镜像概念：从docker服务器拉取的tag发布镜像,仅有读权限
容器概念：基于镜像的映像版本,无论如何修改都不影响源镜像

4.1 docker组权限

// 添加
sudo usermod -aG docker $USER
//  删除
sudo gpasswd -d $USER docker

4.2 容器管理

4.2.1 基本操作

// 查看 CONTAINER ID
docker ps -a 

// 启动
docker start <CONTAINER ID-前三位即可> 
// 停止 - 交互命令下exit直接退出
docker stop <CONTAINER ID>
// 重启
docker restart <CONTAINER ID> 
// 删除
docker rm <CONTAINER ID>

// 清理所有处于终止状态的容器
docker container prune

4.2.2 -d 后台启动后如何进入容器

// 进入容器，从容器退出，不会导致容器的停止（推荐）
docker exec -it <CONTAINER ID-前三位即可> /bin/bash	
// 从容器退出，会导致容器的停止
docker attach <CONTAINER ID>

4.2.3 导出和导入容器

导出:docker export <CONTAINER ID> > openharmony.tar.gz  
导入：cat openharmony.tar.gz | docker import - docker/openharmony:v1  
	或 docker import https://example.com/exampleimage.tgz example/imagerepo

4.3 镜像管理

// 查看当前系统已安装 image
docker images	

// 先停止容器,再删除容器
docker ps -a
docker stop <CONTAINER ID-前三位即可>
docker rm <CONTAINER ID-前三位即可>
// 删除image
docker rmi <IMAGE ID-前三位即可>
	-f:强制删除镜像,即便是有容器引用该镜像
	-no-prune:不删除未带标签的父镜像
// 清理image	
docker image prune
	-f:强制删除镜像,无需弹框确认
	-a:强制删除所有没有用的镜像,不仅只是临时文件

// 更改用户所属组
chown -R user:group filename
