Linux CEF（Chromium Embedded Framework）源码下载编译

背景

由于CEF默认的二进制分发包不支持音视频播放，需要自行编译源码，将ffmpeg开关打开才能支持。这里介绍的是Linux平台下的CEF源码下载编译过程。

Windows平台参考：
《Windows 编译CEF源码详细记录》

前置条件

下载的过程非常艰辛，因为硬性要求比较高。

16GB RAM （推荐 32GB+ ）
120GB SSD硬盘空闲空间起步（避免机械硬盘）
100Mbps带宽（包括代理带宽）以及100G以上的代理流量

这里额外说明一下，下载过程总是失败，大概率原因是因为网络的问题，尤其是网络带宽和代理带宽。这里为什么要单独提代理带宽呢，因为公司有提供代理服务，但是只有10Mbps，所以会导致下载超时，服务端关闭连接。

注意，由于一些因素，下载代码的环境是基于WSL，编译的时候是在UOS V20 1050系统上，但总体差异不大，相关路径会有区别，仍有参考价值。

接下来开始下载CEF的代码

下载

创建目录结构

首先，先创建目录结构，最终的目录结构如下：

~/CEF/
  automate/
    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

可以使用以下命令，创建目录

mkdir CEF && cd CEF && mkdir automate && mkdir chromium_git

终端设置代理

这一步非常重要，因为需要让终端走代理，才能正常下载代码

设置终端代理

export http_proxy=127.0.0.1:7890
export https_proxy=127.0.0.1:7890

通常情况下，这样就可以了，但由于公司的代理问题，设置了代理之后，bitbucket.org域名无法访问，所以我这里将bitbucket.org域名排除在外，这一步因人而异，但基本是不需要这一步的。

export no_proxy=localhost,bitbucket.org

验证代理是否设置成功

leoya@leoya-PC:~$ curl -I https://chromium.googlesource.com
HTTP/1.1 200 Connection established

HTTP/2 200 
content-security-policy: script-src 'nonce-WfQMl6EHcID6PtyTna5LNQ' 'unsafe-inline' 'strict-dynamic' https: http: 'unsafe-eval';object-src 'none';base-uri 'self';report-uri https://csp.withgoogle.com/csp/gerritcodereview/1
content-type: text/html; charset=utf-8
strict-transport-security: max-age=31536000; includeSubDomains; preload
x-content-type-options: nosniff
x-frame-options: SAMEORIGIN
x-xss-protection: 0
date: Fri, 30 Jun 2023 02:04:17 GMT
alt-svc: h3=":443"; ma=2592000,h3-29=":443"; ma=2592000

这里通过curl去获取响应信息，能获取到状态码200或者304，即说明访问正常。可以额外对bitbucket.org也测试一下，如果访问失败，那说明需要将它排除在代理规则内，通过上述方法或者代理软件（如clash）设置代理规则为直连即可。

设置git代理

git config --global http.proxy 127.0.0.1:7890
git config --global https.proxy 127.0.0.1:7890

下载脚本

在CEF根目录下，下载depot_tools，并配置环境变量

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=/home/leoya/CEF/depot_tools:$PATH

下载automate-git.py脚本，这里需要在CEF/automate目录下

cd automate/
wget https://bitbucket.org/chromiumembedded/cef/raw/master/tools/automate/automate-git.py

创建 ~/CEF/chromium_git/update.sh脚本

#!/bin/bash
python3 ../automate/automate-git.py --download-dir=/home/leoya/CEF/chromium_git --depot-tools-dir=/home/leoya/CEF/depot_tools --no-distrib --no-build

执行脚本

设置权限并执行

chmod 755 update.sh
./update.sh

接下来就是无尽的等待。

这里要特别注意depot_tools的更新进度，每次执行脚本的时候，它都会先更新depot_tools，如果更新状态过慢，可能网络有问题。

下载cef仓库的时候一般是没什么问题的。

这里最关键的是下载chromium源码的环节，因为脚本执行中断往往就是在这个环节。因为网络稳定性、下载速率等问题，导致出错。

当你看到Still working on字样的时候，恭喜你，你已经迈过了最艰难的环节，接下来就是下载终端，重试的成本也比较低，因为不用重新下载chromium源码。

报错信息总结

以下原因解释不一定正确，仅供参考
1.

[1:38:14] error: RPC failed; curl 56 GnuTLS recv error (-9):Error decoding the received TLS packet.[1:30:14] fatal:the remote end hung up unexpectedly
[1:30:14] fatail:"early EOF
[1:30:14] fatat: index-pack failed1:30:16]

Linux 编译CEF源码详细记录,CEF,linux,cef,chromium
这里大概率是网络不稳定导致下载中断

error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: 远端意外挂断了
fatal: 过早的文件结束符（EOF）
fatal: index-pack 失败

这个就是因为下载速率太慢，导致长时间占用连接，服务端就主动关闭了连接。

编译 CEF

接下来即可修改ffmpeg文件以添加音视频的支持了

设置ffmpeg

chromium_git/chromium/src/third_party/ffmpeg/chromium/config/Chromium/linux/x64/config_components.h文件的宏#define CONFIG_SIPR_PARSER 1由0设置为1，即启用。

生成工程

终端输入

export GN_DEFINES="use_sysroot=true symbol_level=1 is_cfi=false use_thin_lto=false use_vaapi=false ffmpeg_branding=Chrome proprietary_codecs=true is_official_build=true use_gnome_keyring=false chrome_pgo_phase=0"

ffmpeg_branding和proprietary_codecs 表示开启多媒体编解码支持，但默认仅支持一小部分，想要支持更多可修改上面 ffmpeg 配置文件。
is_official_build 决定了是否是编译正式版本，指定该参数为 true 基本上都是为了产品发布使用，同时也会在创建解决方案的时候生成带有 sandbox 的解决方案，而不指定这个参数是没有的。
use_jumbo_build 官方资料默认指定，表示是否启用试验性的 jumbo 编译，编译过程会加快很多（至少快 1 小时），但是占用 CPU 和内存（尤其是内存）会剧增。
is_component_build 官方资料默认指定，但我们没有开启，这个参数表示是否启用组件化编译，设置为 true 以后，base、ffmpeg 等等都会被编译为动态库，使用时也是动态链接，编译出来的 cef_sandbox 只有几兆大小，并且你需要复制很多 dll 文件到项目目录下才能运行。

这里需要注意几个参数use_vaapi如果未设置为false，即使安装了vaapi，也会出现头文件的一些错误信息。

chrome_pgo_phase=0 禁用pgo文件。

use_gnome_keyring设置为false

进入code/chromium_git/chromium/src/cef路径，执行脚本，生成工程文件

./cef_create_projects.sh

问题处理

在生成工程的过程中，我这里遇到了很多错误，大多是缺失库。

See //build/config/BUILDCONFIG.gn:352:3: which caused the file to be included.

尝试了下载pgo文件，但失败，于是将其chrome_pgo_phase禁用

export GN_DEFINES="use_sysroot=false symbol_level=1 is_cfi=false use_thin_lto=false use_vaapi=false ffmpeg_branding=Chrome proprietary_codecs=true is_official_build=true use_gnome_keyring=false chrome_pgo_phase=0"

若还是提示此错误，则可修改chromium_git/chromium/src/build/config/compiler/pgo/pgo.gni文件，最后的位置处加上chrome_pgo_phase = 0

  chrome_pgo_phase = 0
  if (!dcheck_always_on && is_official_build &&
      # TODO(crbug.com/1052397): Remove chromeos_is_browser_only once
      # target_os switch for lacros-chrome is completed.

      (is_high_end_android || is_win || is_mac || is_fuchsia ||
       (is_linux && !is_castos && !chromeos_is_browser_only))) {
    chrome_pgo_phase = 2
  }
# 手动添加
  chrome_pgo_phase = 0
  # When using chrome_pgo_phase = 2, read profile data from this path.
  pgo_data_path = ""
}

当问题都解决后，就可以开始编译源码了。

开始编译

到code/chromium_git/chromium/src路径下

# debug lib
ninja -C out/Debug_GN_x64 cefclient cefsimple ceftests chrome_sandbox
# release lib
ninja -C out/Release_GN_x64 cefclient cefsimple ceftests chrome_sandbox

这里直接执行的第二条命令

在编译过程中，也会出现错误，不过好在是增量编译，报错不会影响已经编译好的产物。

问题处理

这个错误提示是最明显的了，安装python的importlib_metadata库即可

pip3 install importlib_metadata

如果pip命令未找到，那么先安装pip再执行上面的命令

当编译完成时，终端显示内容：

生成CEF二进制分发包

记得选上--x64-build，否则默认为x86，会提示找不到头文件。生成的路径为/code/chromium_git/chromium/src/cef/binary_districhromium/src/cef/binary_distrib，会默认打包为zip压缩包

code/chromium_git/chromium/src/cef/tools$
# 打包Release
./make_distrib.sh --ninja-build --minimal --x64-build

生成的包名：
cef_binary_113.3.5+g0b33855+chromium-113.0.5672.129_linux64_minimal

# 同时打包Debug和Release
./make_distrib.sh --ninja-build --x64-build

生成的包名：

cef_binary_113.3.5+g0b33855+chromium-113.0.5672.129_linux64

sudo apt install doxygen

当然也可以禁用生成doc文档，就不需要安装了。

总结

由于是事后记录，出错的问题未记录解决方案难免有疏漏。我在下载、编译、生成的阶段中，都会出现很多问题，但总体而言，Linux平台的CEF源码编译还算比较顺畅。
