Linux CEF（Chromium Embedded Framework）源碼下載編譯

背景

由于CEF默認(rèn)的二進(jìn)制分發(fā)包不支持音視頻播放，需要自行編譯源碼，將ffmpeg開關(guān)打開才能支持。這里介紹的是Linux平臺(tái)下的CEF源碼下載編譯過(guò)程。

Windows平臺(tái)參考：
《Windows 編譯CEF源碼詳細(xì)記錄》

前置條件

下載的過(guò)程非常艱辛，因?yàn)橛残砸蟊容^高。

• 16GB RAM （推薦 32GB+ ）
• 120GB SSD硬盤空閑空間起步（避免機(jī)械硬盤）
• 100Mbps帶寬（包括代理帶寬）以及100G以上的代理流量

這里額外說(shuō)明一下，下載過(guò)程總是失敗，大概率原因是因?yàn)榫W(wǎng)絡(luò)的問(wèn)題，尤其是網(wǎng)絡(luò)帶寬和代理帶寬。這里為什么要單獨(dú)提代理帶寬呢，因?yàn)楣居刑峁┐矸?wù)，但是只有10Mbps，所以會(huì)導(dǎo)致下載超時(shí)，服務(wù)端關(guān)閉連接。

注意，由于一些因素，下載代碼的環(huán)境是基于WSL，編譯的時(shí)候是在UOS V20 1050系統(tǒng)上，但總體差異不大，相關(guān)路徑會(huì)有區(qū)別，仍有參考價(jià)值。

接下來(lái)開始下載CEF的代碼

下載

創(chuàng)建目錄結(jié)構(gòu)

首先，先創(chuàng)建目錄結(jié)構(gòu)，最終的目錄結(jié)構(gòu)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，創(chuàng)建目錄

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

終端設(shè)置代理

這一步非常重要，因?yàn)樾枰尳K端走代理，才能正常下載代碼

設(shè)置終端代理

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

通常情況下，這樣就可以了，但由于公司的代理問(wèn)題，設(shè)置了代理之后，bitbucket.org域名無(wú)法訪問(wèn)，所以我這里將bitbucket.org域名排除在外，這一步因人而異，但基本是不需要這一步的。

export no_proxy=localhost,bitbucket.org

驗(yàn)證代理是否設(shè)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

alt-svc: h3=":443"; ma=2592000,h3-29=":443"; ma=2592000

這里通過(guò)curl去獲取響應(yīng)信息，能獲取到狀態(tài)碼200或者304，即說(shuō)明訪問(wèn)正常?？梢灶~外對(duì)bitbucket.org也測(cè)試一下，如果訪問(wèn)失敗，那說(shuō)明需要將它排除在代理規(guī)則內(nèi)，通過(guò)上述方法或者代理軟件（如clash）設(shè)置代理規(guī)則為直連即可。

設(shè)置git代理

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

下載腳本

在CEF根目錄下，下載depot_tools，并配置環(huán)境變量

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

下載automate-git.py腳本，這里需要在CEF/automate目錄下

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

創(chuàng)建 ~/CEF/chromium_git/update.sh腳本

#!/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

執(zhí)行腳本

設(shè)置權(quán)限并執(zhí)行

chmod 755 update.sh
./update.sh

接下來(lái)就是無(wú)盡的等待。

這里要特別注意depot_tools的更新進(jìn)度，每次執(zhí)行腳本的時(shí)候，它都會(huì)先更新depot_tools，如果更新狀態(tài)過(guò)慢，可能網(wǎng)絡(luò)有問(wèn)題。

下載cef倉(cāng)庫(kù)的時(shí)候一般是沒(méi)什么問(wèn)題的。

這里最關(guān)鍵的是下載chromium源碼的環(huán)節(jié)，因?yàn)槟_本執(zhí)行中斷往往就是在這個(gè)環(huán)節(jié)。因?yàn)榫W(wǎng)絡(luò)穩(wěn)定性、下載速率等問(wèn)題，導(dǎo)致出錯(cuò)。

當(dāng)你看到Still working on字樣的時(shí)候，恭喜你，你已經(jīng)邁過(guò)了最艱難的環(huán)節(jié)，接下來(lái)就是下載終端，重試的成本也比較低，因?yàn)椴挥弥匦孪螺dchromium源碼。

接下來(lái)見證下載成功的時(shí)刻?。?！

報(bào)錯(cuò)信息總結(jié)

以下原因解釋不一定正確，僅供參考
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]

這里大概率是網(wǎng)絡(luò)不穩(wěn)定導(dǎo)致下載中斷

error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: 遠(yuǎn)端意外掛斷了
fatal: 過(guò)早的文件結(jié)束符（EOF）
fatal: index-pack 失敗

這個(gè)就是因?yàn)橄螺d速率太慢，導(dǎo)致長(zhǎng)時(shí)間占用連接，服務(wù)端就主動(dòng)關(guān)閉了連接。

編譯 CEF

接下來(lái)即可修改ffmpeg文件以添加音視頻的支持了

設(shè)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設(shè)置為1，即啟用。

生成工程

終端輸入

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 表示開啟多媒體編解碼支持，但默認(rèn)僅支持一小部分，想要支持更多可修改上面 ffmpeg 配置文件。
• is_official_build 決定了是否是編譯正式版本，指定該參數(shù)為 true 基本上都是為了產(chǎn)品發(fā)布使用，同時(shí)也會(huì)在創(chuàng)建解決方案的時(shí)候生成帶有 sandbox 的解決方案，而不指定這個(gè)參數(shù)是沒(méi)有的。
• use_jumbo_build 官方資料默認(rèn)指定，表示是否啟用試驗(yàn)性的 jumbo 編譯，編譯過(guò)程會(huì)加快很多（至少快 1 小時(shí)），但是占用 CPU 和內(nèi)存（尤其是內(nèi)存）會(huì)劇增。
• is_component_build 官方資料默認(rèn)指定，但我們沒(méi)有開啟，這個(gè)參數(shù)表示是否啟用組件化編譯，設(shè)置為 true 以后，base、ffmpeg 等等都會(huì)被編譯為動(dòng)態(tài)庫(kù)，使用時(shí)也是動(dòng)態(tài)鏈接，編譯出來(lái)的 cef_sandbox 只有幾兆大小，并且你需要復(fù)制很多 dll 文件到項(xiàng)目目錄下才能運(yùn)行。

這里需要注意幾個(gè)參數(shù)use_vaapi如果未設(shè)置為false，即使安裝了vaapi，也會(huì)出現(xiàn)頭文件的一些錯(cuò)誤信息。

chrome_pgo_phase=0 禁用pgo文件。

use_gnome_keyring設(shè)置為false

進(jìn)入code/chromium_git/chromium/src/cef路徑，執(zhí)行腳本，生成工程文件

./cef_create_projects.sh

問(wèn)題處理

在生成工程的過(guò)程中，我這里遇到了很多錯(cuò)誤，大多是缺失庫(kù)。

若還是提示此錯(cuò)誤，則可修改chromium_git/chromium/src/build/config/compiler/pgo/pgo.gni文件，最后的位置處加上chrome_pgo_phase = 0

  }
# 手動(dòng)添加
  chrome_pgo_phase = 0
  # When using chrome_pgo_phase = 2, read profile data from this path.

當(dāng)問(wèn)題都解決后，就可以開始編譯源碼了。

ninja -C out/Release_GN_x64 cefclient cefsimple ceftests chrome_sandbox

這里直接執(zhí)行的第二條命令

在編譯過(guò)程中，也會(huì)出現(xiàn)錯(cuò)誤，不過(guò)好在是增量編譯，報(bào)錯(cuò)不會(huì)影響已經(jīng)編譯好的產(chǎn)物。

問(wèn)題處理

gperf錯(cuò)誤

sudo apt install gperf

這個(gè)錯(cuò)誤提示是最明顯的了，安裝python的importlib_metadata庫(kù)即可

pip3 install importlib_metadata

如果pip命令未找到，那么先安裝pip再執(zhí)行上面的命令

當(dāng)編譯完成時(shí)，終端顯示內(nèi)容：

當(dāng)然也可以禁用生成doc文檔，就不需要安裝了。

總結(jié)

由于是事后記錄，出錯(cuò)的問(wèn)題未記錄解決方案難免有疏漏。我在下載、編譯、生成的階段中，都會(huì)出現(xiàn)很多問(wèn)題，但總體而言，Linux平臺(tái)的CEF源碼編譯還算比較順暢。
