Windows 版本的 Webrtc 的編譯 ( 基於聲網映象 )
Windows 版本的 Webrtc 的編譯 ( 基於聲網映象 )
前期準備：
1. 作業系統
Windows 10 Preview Build 17063或之後的版本，需要命令 curl 和 tar ， 以及 PowerShell 的功能
怎麼驗證是否支援 curl 與 tar， 開啟 PowerShell
這個是必須要支援的，因為在 webrtc 的下載過程中，需要這些指令支援！
2. git 的安裝
git - https://git-scm.com/download/win
3. vs2017 的安裝
visualstudio2017community - https://download.visualstudio.microsoft.com/download/pr/aaebc214-bc67-4137-9bea-04fcb0c90720/2e18f27594472d0c7515d9cbe237bd56/vs_community.exe
3.1 Modify "Windows Software Development Kit" > +Debugging Tools for Windows 這個是必須的
這個 Windows Phone Kits 應該有多個版本，都全部勾選上 Debugging Tools For Windows
3.2 SDK 版本的選擇
這些必須選擇好，否則編譯過程中依賴的 LIB, INCLUDE 的就不完整，導致編譯失敗，比如：
AssertionError File "C:/Users/Administrator/webrtc/src/build/toolchain/win/setup_toolchain.py", line 278, in main
assert vc_lib_atlmfc_path
4. python 的安裝
python2 - https://www.python.org/downloads/release/python-2716/
4.1 pip 的安裝
https://www.cnblogs.com/baiyuer/p/9606773.html
環境變數的配置
4.2 pywin32 模組的安裝 pip install pywin32
這個模組不安裝，編譯過程中，會出現 “ No module named win32file ” 的錯誤
環境配置
1. git 的基本配置，把下述內容儲存為檔案 git_env.bat 檔案，等待備用

set GYP_DEFINES = target_arch=x64
set GYP_MSVS_VERSION=2017
set LIB=C:\Program Files (x86)\Windows Kits\10\Lib\10.0.17763.0\ucrt\x64;F:\Windows Kits\10\Lib\10.0.17763.0\um\x64;
set INCLUDE=C:\Program Files (x86)\Windows Kits\10\Include\10.0.17763.0\shared;F:\Windows Kits\10\Include\10.0.17763.0\ucrt;F:\Windows Kits\10\Include\10.0.17763.0\um;F:\Windows Kits\10\Include\10.0.17763.0\winrt;
set DEPOT_TOOLS_UPDATE=0
set GYP_MSVS_VERSION=2017
set GYP_MSVS_OVERRIDE_PATH=C:\Program Files (x86)\Microsoft Visual Studio\2017\Community
set GYP_DEFINES=target_arch=x64
set GYP_GENERATORS=msvs-ninja,ninja 千萬注意 LIB， INCLUDE， GYP_MSVS_OVERRIDE_PATH，GYP_MSVS_VERSION 要修改為你本地安裝的實際路徑，上述例子是我機器上的絕對路徑！！！！！！
編譯過程
1. 首先執行上述的指令碼 git_env.bat
2. 下載 depot_tools
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git -b gitlab
3. 配置 depot_tools 的環境變數，見上述 4.1 中的截圖
4.建立目錄 webrtc
5. 開啟 cmd.exe 並進入到 webrtc 目錄
6. gclient config --name src https://chromium.googlesource.com/external/webrtc.git@gitlab
7. 配置環境變數
7.1 set CDS_CLANG_BUCKET_OVERRIDE=http://120.92.49.206:3232/chromiumsrc/commondatastorage/raw/master/public/chromium-browser-clang
7.2 set DEPOT_TOOLS_WIN_TOOLCHAIN=0
8. 同步 path
gclient sync --patch-ref=https://chromium.googlesource.com/chromium/src/build.git@gitlab
9. 執行上述指令碼 pre_build.bat
10. gn gen out/Default --ide=vs2017
11. ninja -C out/Default
如果順利，基本可以編譯通過！
Good luck!
