- 安装 depot_tools
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
把 depot_tools 加入环境变量
export PATH=`pwd`/depot_tools:"$PATH"
- clone 源代码
创建一个文件夹用来存放 WebRTC 源代码，比如 mkdir ~/webrtc， 进入刚才创建的文件夹执行
fetch --nohooks webrtc_ios
gclient sync
然后就是漫长的等待中...
完全 sync 完成后会在 webrtc 目录下生成一个 src 目录，进入 src 目录会看到类似 https://chromium.googlesource.com/external/webrtc/+/master 这个样的目录，只不过多了 third-party 的一些依赖文件, branch 57 之后 sync 很快哦
- 编译 framework
运行命令 gclient runhooks
进入 src 目录，然后执行
./tools_webrtc/ios/build_ios_libs.py
就可以编译出 framework 文件了。
可以通过 ./tools_webrtc/ios/build_ios_libs.py --help 查看编译选项
默认会编译出全部架构的 ['arm64', 'arm', 'x64', 'x86'] 的 framework 文件，如果想要编译成静态库也可以加上 -b static_only，如果只想编译 ARM 的架构可以 ./tools_webrtc/ios/build_ios_libs.py --arch {'arm64','arm'} (老版本的目录为 tools-webrtc)
- 使用 Xcode 查看和编译 WebRTC 源码
WebRTC 不支持 Xcode 原生编译，用 Xcode 编译也是调用的 ninja 去编译
先生成 workspace 文件，还是进入上面提到的 src 的目录
gn gen out/ios --args='target_os="ios" target_cpu="arm64" is_component_build=false' --ide=xcode
打开工程文件，就可以编译和查看源码了
open -a Xcode.app out/ios/all.xcworkspace
-
代码更新
以后更新 webrtc 代码只需要进入 src 目录git pull就行， 定期的更新依赖，使用gclient sync -
有不能编译成功的可以留言哦 😄

-bash: gn: command not found
大佬，这种应该怎么解决呢

大神，这个log主要是什么错误引起的，需要怎么做呢
-bash: ./tools-webrtc/ios/build_ios_libs.py: No such file or directory ,ls 后是有对应文件的.我后面直接py文件拖到终端raceback (most recent call last):

问下楼主,我第一次安装好后编译不成功,后来我删除了重新编译结果报上面的错误~~
File "/Users/mmj/Desktop/sp/w/ship/depot_tools/gclient.py", line 2618, in <module>
raise CalledProcessError(retcode, cmd, output=output)
subprocess.CalledProcessError: Command '('gclient', 'sync', '--nohooks', '--with_branch_heads')' returned non-zero exit status 1 ,,,,,,,,,,,,这安装也不对吧
报下面的错:
