webrtc编译填坑记录

参考别人的文档

WebRTC填坑wiki

一、下载源码

1.国内镜像

由于一些特殊原因，最好采用国内镜像下载。参考webrtc国内镜像

2.windows

二、编译源码

1.ios/Mac

参考webrtc国内镜像中编译ios/Mac版本的命令，但有可能出现一些问题。

• python版本太高
  比如python3.*，执行命令

 gclient sync --patch-ref=https://chromium.googlesource.com/chromium/src/build.git@gitlab

出现错误如下：

/Users/username/Workspace/webrtc/depot_tools/update_depot_tools sync --patch-ref=https://chromium.googlesource.com/chromium/src/build.git@gitlab
Traceback (most recent call last):
  File "/Users/username/Workspace/webrtc/depot_tools/metrics.py", line 267, in print_notice_and_exit
    yield
  File "/Users/username/Workspace/webrtc/depot_tools/gclient.py", line 3168, in <module>
    sys.exit(main(sys.argv[1:]))
  File "/Users/username/Workspace/webrtc/depot_tools/gclient.py", line 3154, in main
    return dispatcher.execute(OptionParser(), argv)
  File "/Users/username/Workspace/webrtc/depot_tools/subcommand.py", line 252, in execute
    return command(parser, args[1:])
  File "/Users/username/Workspace/webrtc/depot_tools/gclient.py", line 2711, in CMDsync
    ret = client.RunOnDeps('update', args)
  File "/Users/username/Workspace/webrtc/depot_tools/gclient.py", line 1716, in RunOnDeps
    self._CheckConfig()
  File "/Users/username/Workspace/webrtc/depot_tools/gclient.py", line 1364, in _CheckConfig
    actual_url = scm.GetActualRemoteURL(self._options)
  File "/Users/username/Workspace/webrtc/depot_tools/gclient_scm.py", line 153, in GetActualRemoteURL
    actual_remote_url = self._get_first_remote_url(self.checkout_path)
  File "/Users/username/Workspace/webrtc/depot_tools/gclient_scm.py", line 141, in _get_first_remote_url
    return log.splitlines()[0].split(' ', 1)[1]
TypeError: a bytes-like object is required, not 'str'

解决方法：此时把python改为2.7.*就可以了，我是用anaconda创建的虚拟环境，python2.7.17，这样就可以啦。

• ios证书签名问题
  执行命令生成xcode工程文件，

gn gen out/ios --args='target_os="ios" target_cpu="arm64" is_component_build=false' --ide=xcode

出现错误：

Automatic code signing identity selection was enabled but could
not find exactly one code signing identity matching
iPhone Developer. Check that your keychain
is accessible and that there is a valid code signing identity
listed by `xcrun security find-identity -v -p codesigning`
TIP: Simulator builds don't require code signing...
ERROR at //build/config/ios/ios_sdk.gni:142:7: Assertion failed.
      assert(false)

解决方法1：修改配置，不使用签名证书，命令如下

gn gen out/ios --args='target_os="ios" target_cpu="arm64" is_component_build=false ios_enable_code_signing=false' --ide=xcode
