设置代理
# 可以写入 .bash_profile 文件中
export HTTP_PROXY=http://127.0.0.1:1087
export HTTPS_PROXY=http://127.0.0.1:1087
$ git config --global http.proxy http://127.0.0.1:1087
$ git config --global https.proxy https://127.0.0.1:1087安装xocde
在appstore搜索安装xcode12.5
安装brew
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"安装xcode-select
sudo xcode-select --install
同步WebRTC
# 1.切换到 webrtc
cd /home/xxx/Desktop
mkdir webrtc
cd webrtc
# 2.安装和设置代码下载工具
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
echo -e "\nexport PATH=$PWD/depot_tools:$PATH" >> $HOME/.bash_profile
echo -e "\nexport DEPOT_TOOLS_UPDATE=0" >> $HOME/.bash_profile
source $HOME/.bash_profile
# 3.设置 boto 代理，创建http_proxy.boto文件，在里面输入如下内容：
[Boto]
proxy=127.0.0.1
proxy_port=7890 #此端口号为代理端口号
# 4.配置坏境变量
$ echo -e "\nexport NO_AUTH_BOTO_CONFIG=$PWD/http_proxy.boto" >> $HOME/.bash_profile
$ source $HOME/.bash_profile
# 5.编译前,请检查 .gclient 的配置
solutions = [
{
"name": "src",
"url": "https://webrtc.googlesource.com/src.git",
"deps_file": "DEPS",
"managed": False,
"custom_deps": {},
},
]
// 这个地方一定要写对
target_os = ["ios", "mac"]
# 6.下载源代码
$ export GYP_DEFINES="OS=ios"
$ fetch --nohooks webrtc_ios
将分支定位到m84
$ git checkout -b m84 refs/remotes/branch-heads/4147
$ gclient sync
获取签名，没有签名不能真机调试
xcrun security find-identity -v -p codesigning
1) 2D9CD6EEFE84AC7CA1F2CA3E877861BBF8A66D4B "Apple Development: xxxxxx (yyyy)"代码编译，不需要真机调试把ios_code_signing_identity="yyyy"替换成 ios_enable_code_signing=false
1,ios 64版本：
gn gen out/ios_64 --args='target_os="ios" target_cpu="arm64" is_component_build=false ios_code_signing_identity="yyyy" is_debug=true' --ide=xcode
2,ios 32版本：
gn gen out/ios_32 --args='target_os="ios" target_cpu="arm" is_component_build=false ios_code_signing_identity="yyyy" is_debug=true' --ide=xcode
3,模拟器32版本：
gn gen out/ios_x32 --args='target_os="ios" target_cpu="x86" is_component_build=false ios_code_signing_identity="yyyy" is_debug=true' --ide=xcode
4,模拟器64版本：
gn gen out/ios_x64 --args='target_os="ios" target_cpu="x64" is_component_build=false ios_code_signing_identity="yyyy" is_debug=true' --ide=xcode
5，打开xcode编译即可：
open -a Xcode.app out/ios_64/all.xcworkspace编译Webrtc.framework动态库
方法一：
用xcode打开all.xcworkspace，编译 target ：AppRTCMobile就能生成WebRTC.framework
方法二：
ninja -C out/ios_64 AppRTCMobile
方法三：
python tools_webrtc/ios/build_ios_libs.py --output-dir out/ios --arch arm64 --extra-gn-args rtc_include_tests=false rtc_build_tools=false rtc_build_examples=false方法四：
备份build_ios_libs.py文件
mv ./tools_webrtc/ios/build_ios_libs.py ./tools_webrtc/ios/build_ios_libs.py.bak
修改build_ios_libs.py
