    ~/code/
      automate/           <-- 全部脚本放到这里
        automate-git.py   <-- CEF build script
      chromium_git/
        cef/              <-- CEF source checkout
        chromium/
          src/            <-- Chromium source checkout
        update.[bat|sh]   <-- Bootstrap script for automate-git.py
      depot_tools/        <-- Chromium build tools
  • 安装ninja,并加添到系统环境变量Clicked Me
  • 最好不要在nvme盘上clone,可能导致clone卡死

详说

下载

  1. 打开打SS，服务器选择一个本地代理端口为1081，勾选来自局域网连接，不用启动代理！！！！
  2. 在automate下创建update.bat，内容为如下，执行该脚本，支持mp3 mp4~下载很快，代码可能就20来G样子，我下载速度10M/s还是很快，主要参考地址
  3. 该脚本会先下载depot_tools这个项目，再通过depot_tools下载源码，如果源码下载失败，需要重新下载源码可以不用再下载depot_tools，调用automate-git.py加一个参数,例： –depot-tools-dir=D:\code\chromium_git\depot_tools

编译过程

  • 如下的全部脚本文件放到code/automate下

  • 修改源文件准备支持mp3,mp4,针对win32的话，修改F:\code\chromium_git\chromium\src\third_party\ffmpeg\chromium\config\Chrome\win\ia32\config.h,把部分#define 由0改为1，针对此操作，我写了一个脚本修改支持

  • 这些是要改的内容，写到本地文件mp4_support.txt

  • 再创建一个启动RunSupportMp4.bat 并运行

    2
    python SupportMp4.py F:/code/automate/mp4_support.txt F:/code/chromium_git/chromium/src/third_party/ffmpeg/chromium/config/Chrome/win/ia32/config.h
    pause

  • 创建env.bat脚本

    1
    set path=%path%;F:\code\depot_tools;F:\code\chromium_git\chromium\src

  • 创建BuildNinga,Ninga是一个超快的编译工具，并小巧

    pause

    如果前面全部都顺利的话，你会看到F:\code\chromium_git\chromium\src\out目录，里面有一堆准备使用ninga来编译的工程！！！
    最后一步,执行如下操作，然后进行死亡等待

    1
    2
    cd F:\code\chromium_git\chromium\src
    ninja -C out\Release_GN_x86 cef

编译好后,打开地址F:\code\chromium_git\chromium\src\out\Release_GN_x86 测试有没有成功支持mp4: http://html5test.com/

出错解决方案

源码下载完毕，卡到Resolving deltas: 100% (10224481/10224481), done

这个问题，折腾了我2天，想通过设置代理的方式解决，失败告终，但我通过奇技淫巧也成功编译了，首先停止脚本运行，修改一下automate-git.py，把13**多行的,sync git clone — job 16这句注释调，再执行下载脚本，跳过下载源码的过程

python ImportError: No module named win32file

参考：点这里

解决方法：cd 到depot_tools下的bootstrap-3_8_0_chromium_8_bin,然后进入python里面,给python安装 pywin32这个库

python -m pip install pywin32

卡到下载depot_tool位置

修改脚本 automate-git.py 188行，使用下载支持proxy请求
