? ? ? build example部分宜鸯；

goole 官方編譯:

下載代碼(代碼總量有10多G）:

$ cd /home/foo/src

$ mkdir webrtc-checkout

$ cd webrtc-checkout

$ fetch --nohooks webrtc

$ gclient sync

切換到m79分支:

$ cd src

$ git checkout -b m79 refs/remotes/branch-heads/m79

$ gclient sync

設(shè)置編譯選項:

In Linux Debian Stretch with GCC 6.3 this works:

$ gn gen out/mybuild-m79 --args='is_debug=false is_component_build=false is_clang=false rtc_include_tests=false rtc_use_h264=true rtc_enable_protobuf=false use_rtti=true use_custom_libcxx=false treat_warnings_as_errors=false use_ozone=true'

$ gn gen out/mybuild-m79 --args='is_debug=true is_component_build=false is_clang=false rtc_include_tests=false rtc_use_h264=true rtc_enable_protobuf=false use_rtti=true use_custom_libcxx=false treat_warnings_as_errors=false use_ozone=true'

編譯:

$ ninja -C out/mybuild-m79

編譯結(jié)果:

find out/mybuild-m79/? -name "*.a" | wc -l

132

會發(fā)現(xiàn)132個 .a文件, 其中包含 libwebrtc.a

gclient sync? 遇到的問題：

問題:

urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

解決:

https://medium.com/@moreless/how-to-fix-python-ssl-certificate-verify-failed-97772d9dd14c

export PYTHONHTTPSVERIFY=0

或者在python腳本里邊加入以下語句:

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

解決:

原因就是你改動了另伍，src/third_party這個文件夾下面的文件大渤，解決方法就是到

cd src/third_party

git status

根據(jù)git status 看看那些改動

然后 git add 相應(yīng)的改動即可

問題:

depot_tools\download_from_google_storage.py

這個腳本下載文件失敗;

解決:

直接讓該腳本的main函數(shù) return? 0 即可,? 即我們不下載相關(guān)內(nèi)容,? 因為我們編譯webrtc 不需要這些, 這些依賴可能是編譯 chrome 所需要的內(nèi)容;
