cef 不更新编译

1，安装"Debugging Tools for Windows“

Control Panel → Programs → Programs and Features → Select the “Windows Software Development Kit” → Change → Change → Check “Debugging Tools For Windows” → Change. Or, you can download the standalone SDK installer and use it to install the Debugging Tools.

2，gn gen out\Default   

gn gen --ide=vs --filters=//chrome;//third_party/WebKit/*;//gpu/*. --no-deps out\Default

输入参数：(gn args out/Default) or on the gn gen command line (gn gen out/Default --args="is_component_build = true is_debug = true")

报错 

ERROR at //cef/BUILD.gn:140:1: Assertion failed.

assert(!enable_print_preview)

可以键入命令输入编译参数： gn args out/Default 在弹出的编辑notepad里面加入一行： 

enable_print_preview = false
enable_widevine = true
clang_use_chrome_plugins = false

这个文件保存在 out/Default/args.gn

 加速：

• is_component_build = true - this uses more, smaller DLLs, and incremental linking.
• enable_nacl = false - this disables Native Client which is usually not needed for local builds.
• target_cpu = "x86" - x86 builds are slightly faster than x64 builds and support incremental linking for more targets. Note that if you set this but don‘t’ set enable_nacl = false then build times may get worse.
• blink_symbol_level = 0 - turn off source-level debugging for blink to reduce build times, appropriate if you don't plan to debug blink.

  • # Build arguments go here.
    # See "gn args  --list" for available build arguments.
    enable_print_preview = false
    enable_widevine = true
    clang_use_chrome_plugins = false
    is_component_build = true
    enable_nacl = false 
    target_cpu = "x86" 

     

  • ../../base/win/windows_version.cc(26,2):  error: Creators Update SDK (10.0.15063.468) required.

  • 安装windows sdk 

  • 这个原因是因为新版的win10 sdk改变了目录结构，使得编译软件无法找到必要的处理程序。解决办法如下：

    • 进入C:\Program Files (x86)\Windows Kits\10\bin，将arm、armx64、x64、x86文件夹备份并删除，
    • 将10.0.15063.0文件夹中的arm、armx64、x64、x86文件夹拖出。
    • 再次运行ninja -C out.gn/x64.release
    • https://developer.microsoft.com/zh-cn/windows/downloads/ windows sdk下载。

    • //chrome_elf/BUILD.gn:10:1: Can't load input file.
      import("//cef/libcef/features/features.gni")
      
      src/build.gn remove //cef
      
      chrome_elf 移除 cef有关
