Ubuntu20已自带python3.8.5，执行以下命令，切换python3：
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 150
安装pip
sudo apt-get install python3-pip

sudo apt-get update
sudo apt -y upgrade
Enter fullscreen mode Exit fullscreen mode

1.3 配置sh为bash 

ls -l /bin/sh     
#如果显示为“/bin/sh -> bash”则为正常，否则请按以下方式修改： 
sudo dpkg-reconfigure dash      #然后选择no
或者：
sudo rm -rf /bin/sh
sudo ln -s /bin/bash /bin/sh
Enter fullscreen mode Exit fullscreen mode

1.4 git lfs安装 

curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | bash
apt-get install git-lfs
apt install git-lfs
git lfs install
Enter fullscreen mode Exit fullscreen mode

1.5 repo工具安装 

curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > repo
chmod a+x repo
mv repo /usr/local/bin/
Enter fullscreen mode Exit fullscreen mode

1.6 Git配置 

git config --global user.name "shuai"
git config --global user.name "zhuhongtao66"
git config --global user.name "futurezhou"
git config --global user.email "fjq782976686@163.com"
git config --global user.email "1624631650@qq.com"
git config --global core.editor vim
git config --global credential.helper store
git config --global user.email "fengjunqing1@huawei.com"
git config --global user.email "guoshuai48@huawei.com"
Enter fullscreen mode Exit fullscreen mode

1.7 安装hb命令（不常用） 

# 方法一：
# 下载一套master分支的代码然后进入root目录下执行
pip3 install build/lite
vim ~/.bashrc
export PATH=$PATH:~/.local/bin
source ~/.bashrc

# 方法二：
python3 -m pip install --user ohos-build
vim ~/.bashrc
export PATH=$PATH:~/.local/bin
source ~/.bashrc

# 方法三：
# 安装指定版本，君正使用的是0.4.3
python3 -m pip install ohos-build==0.4.3
vim ~/.bashrc
export PATH=$PATH:~/.local/bin
source ~/.bashrc

# 卸载hb命令
pip3 uninstall ohos-build

# 使用hb命令
hb set # 选择系统
hb build # 编译
Enter fullscreen mode Exit fullscreen mode

二 代码下载和编译

2.1 代码下载

  1. master代码下载

    mkdir -p ~/OpenHarmony/master
cd ~/OpenHarmony/master
repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify
repo sync -c 
repo forall -c 'git lfs pull'  # 拉取二进制文件
repo start master --all
bash ./build/prebuilts_download.sh

repo切换分支：
repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify
代码版本回退：
repo forall -c 'commitID=`git log --before "2022-03-18 07:00" -1 --pretty=format:"%H"`; git reset --hard $commitID'
重置工作区, 删除所有修改(记得备份你改的代码): 
repo forall -c "pwd;git reset --hard; git clean -fd"
更新最新代码: 
repo sync -c -j8; repo forall -c "pwd;git lfs install;git lfs pull"
强制同步：
repo sync --force-sync -c

  2. 编译问题三板斧：（前提条件：确保代码同步了最新，ci看板门禁没问题）：

* 遇到prebuilt的相关报错，无脑执行./build/prebuilts_download.sh
* 遇到lfs报错，无脑更新下二进制：repo forall -c "git lfs pull"
* 遇到其他正常模块报错，先到out/rk3568/下面删除对应模块的编译产物再编，实在解决不了，删除整个out
Enter fullscreen mode Exit fullscreen mode

2.2 环境变量设置 

vim /etc/profile
export PATH=$PATH:/home/prebuilts/llvm/llvm/bin
export PATH=~/.local/bin:$PATH
export PATH=~/toolchain/gcc-arm-none-eabi-10.3-2021.10/bin:$PATH
source ~/.bashrc
Enter fullscreen mode Exit fullscreen mode

2.3 代码编译

  • 全量编译 
  ./build.sh --product-name rk3568 --ccache
  ./build.sh --product-name rk3568 --ccache -j16
Enter fullscreen mode Exit fullscreen mode
  • 测试用例编译 
  TDD测试用例：
  ~/OpenHarmony/master/目录下：
  ./build.sh --product-name rk3568 --build-target make_test --ccache #编译所有用例
  ./build.sh --product-name rk3568 --build-target linuxkerneltest # 编译内核测试用例
  ./build.sh --product-name rk3568 -T linuxkerneltest
  编译生成的结果，以二进制形式存储在OpenHarmony/master/out/hispark_taurus/tests下

  XTS测试用例：
  ~/OpenHarmony/master/test/xts/acts/目录下：
  ./build.sh product_name=rk3568 system_size=standard target_subsystem=kernel target_arch=arm64
  ./build.sh product_name=rk3568 system_size=standard target_subsystem=storage # 不指定arch，默认32位
  编译生成的结果，以二进制形式存储在/home/shuai/OpenHarmony/master/out/rk3568/tests/unittest/filemanagement/file_api/filemgmt_libn_test下 (WSL)

  需要重新编译的情况下，一定要先删除out/rk3568/下对应模块的编译产物，再编
  rm -rf ../../../out/rk3568/obj/test/xts
  OH——SDK编译命令：
  ./build.sh --product-name ohos-sdk --disable-package-image --gn-args skip_generate_module_list_file=true --disable-part-of-post-build output_part_rom_status --disable-part-of-post-build get_warning_list --disable-part-of-post-build compute_overlap_rate --gn-args use_thin_lto=false
Enter fullscreen mode Exit fullscreen mode
  • 子系统下单模块编译 
  文件管理子系统单个部件编译：
  ./build.sh --product-name rk3568 --ccache --build-target app_file_service
  ./build.sh --product-name rk3568 --ccache --build-target file_api
  不修改build.gn文件的情况下，可执行快速编译命令：
  ./build.sh --product-name rk3568 --ccache --build-target file_api --fast-rebuild
Enter fullscreen mode Exit fullscreen mode
  • 反编译 
  cd OpenHarmony/master/out/rk3568/lib.unstripped/filemanagement/file_api
  addr2line -Cfi -e libfs.z.so 00033d4e
Enter fullscreen mode Exit fullscreen mode
  • ‍

2.4 GN格式修改

  • 所有的BUILD.gn文件需要使用命令格式化一下，才能通过门禁。 命令类似： 
  ~/OpenHarmony/master/目录下：
  cat kernel/linux/build/test/fuzztest/memory/BUILD.gn | prebuilts/build-tools/linux-x86/bin/gn format --stdin > FORMAT_RESULT.gn;cp -f FORMAT_RESULT.gn kernel/linux/build/test/fuzztest/memory/BUILD.gn;rm FORMAT_RESULT.gn
  cat kernel/linux/build/test/kernel_ltp/kernel_interface_template.gni | prebuilts/build-tools/linux-x86/bin/gn format --stdin > FORMAT_RESULT.gni;cp -f FORMAT_RESULT.gni kernel/linux/build/test/kernel_ltp/kernel_interface_template.gni;rm FORMAT_RESULT.gni
Enter fullscreen mode Exit fullscreen mode

三 VSCode配置

3.1 vscode配置

显示空格和Tab

打开setting,在搜索框中输入renderControlCharacters,选中勾选框,即可显示tab.
在搜索框中输入renderWhitespace,选择all,即可显示空格.
Enter fullscreen mode Exit fullscreen mode

3.2 连接服务器

使用Remote SSHhttps://zhuanlan.zhihu.com/p/412736012

安装 SSH

通过安装 Git 来获取 SSH 功能，如何验证？使用 Win + R + cmd​，打开控制窗口，直接输入 ssh​查看。

添加插件

​Remote - SSH​安装完插件后，在侧边栏可以看到 “远程资源管理器” 图标。

配置SSH密钥

1. 生成ssh密钥
ssh-keygen
或：ssh-keygen -t rsa -C "youremail@example.com"

2. 一般生成的密钥文件，路径为：C:\Users\user\.ssh ，
   找到公钥文件 id_rsa.pub ，复制到远程服务器 根目录 的 .ssh 文件夹中。

3. 生成 authorized_keys 文件
cat id_rsa.pub > authorized_keys
Enter fullscreen mode Exit fullscreen mode

添加配置文件

点击VSCode侧边栏的 “远程资源管理器” 图标，选择 ssh targets​ ，点击右上角的小齿轮（设置），打开编辑 config 文件

Host <远程主机名称1>
    HostName <远程主机1 IP>
    User <用户名1>
    Port <ssh端口，默认22>
    IdentityFile <本机SSH私钥路径>
    ForwardAgent yes <VSCode 自己添加的，不用管>
Enter fullscreen mode Exit fullscreen mode

连接测试 ​

VScode更新导致断连：
1. 删除服务器中的commitID命名的文件

2. 关闭所有vscode窗口，重新打开。
Enter fullscreen mode Exit fullscreen mode

在终端查找Using commit id​并前往服务器~/.vscode-server目录，删除该ID相关的文件

3.3 添加扩展 

GitLens

shell-format
C/C++
Draw.io Integration
Enter fullscreen mode Exit fullscreen mode

3.4 个人设置

VSCode 修改工作区配色|极客教程 (geek-docs.com)

多层级彩色括号，卸载 Bracket-Pair-Colorizer 插件。

// settings.json

  "editor.bracketPairColorization.enabled": true,
  "workbench.colorCustomizations": {
    "editorBracketHighlight.foreground1": "#ffd700",
    "editorBracketHighlight.foreground2": "#da70d6",

    "editorBracketHighlight.foreground6": "#87cefa",
    "editorBracketHighlight.unexpectedBracket.foreground": "#ff0000"
  }
Enter fullscreen mode Exit fullscreen mode

3.5 配置mingw-w64的gcc、g++编译器和GDB调试器

https://zhuanlan.zhihu.com/p/130711420

四 vim安装配置

安装

sudo apt-get install vim-gtk -y
Enter fullscreen mode Exit fullscreen mode

备份并更新配置

// 把原本的文件备份
sudo cp /etc/vim/vimrc /etc/vim/vimrc.back
//删除vimrc
sudo rm /etc/vim/vimrc
// 新建文件vimrc
sudo vi /etc/vim/vimrc
// 进入文件后按“a",表示插入，接下来把下面的内容复制到这个文件中，按”esc“，表示退出，再输入”wq“+”回车“就保存退出了。
Enter fullscreen mode Exit fullscreen mode
