Manual compilation steps for Windows

Before You Start First, be sure to install the prerequisite software. Recommend to use vs2019 Community Edition

Prepare the compilation directory

mkdir webrtc-sdk-checkout
cd webrtc-sdk-checkout

Create .gclient

solutions = [
  { 
    "name"        : 'src',
    "url"         : 'https://github.com/webrtc-sdk/webrtc.git',
    "deps_file"   : 'DEPS',
    "managed"     : False,
    "custom_deps" : {
    },
    "custom_vars": {},
  },
]
target_os  = ['win']

Synchronize source code

gclient sync

Generate ninja compilation directory

set GYP_MSVS_VERSION=2019
set GYP_GENERATORS=ninja,msvs-ninja
set GYP_MSVS_OVERRIDE_PATH=C:\Program Files (x86)\Microsoft Visual Studio\2019\Community

Compile

ninja -C out/Windows-x64-debug
ninja -C out/Windows-x64-release

Compile steps for libwebrtc

Confirm that it is currently in the src.

git clone https://github.com/webrtc-sdk/libwebrtc
