Build using Docker

You will need the following environment.

• Linux (recommended: Ubuntu 18.04 LTS)
• Docker 19.03.8 or above (via apt recommended)
• NVIDIA Container Toolkit

# make sure we have GPUs enabled in containers 
sudo docker run --gpus all nvidia/cuda:10.0-base nvidia-smi

# building. takes approximately 45~ minutes...
git clone https://github.com/ogukei/rigel
cd rigel
sudo docker build -t image-rigel .

# running
sudo docker run --gpus all --network="host" --name rigel -d image-rigel
google-chrome http://localhost:8080

# clean up
sudo docker stop rigel && sudo docker rm rigel

Build manually

The Makefile provides minimum set of tools required to build a libwebrtc linked binary. You will need the following environment to properly make build done.

• Linux (recommended: Ubuntu 18.04 LTS)
• Vulkan Driver Support
• Libraries:
  • Boost 1.70.0 or above (just headers needed)
  • OpenGL Mathematics libglm-dev 0.9 or above
  • Vulkan SDK, libvulkan-dev 1.0 or above

1. In advance, requires libwebrtc compiled using Chromium build toolchain. Use the following git commit hash when you checkout branch in order to ensure that we use the same version of libwebrtc.

   159c16f3ceea1d02d08d51fc83d843019d773ec6

   For more information of WebRTC build instructions, see https://webrtc.org/native-code/development/

   Use the following command to generate Ninja build file.

   gn gen out/Default --args='target_os="linux" is_debug=false rtc_include_tests=false is_component_build=false use_rtti=true'

2. Specify the WebRTC /src directory path to WEBRTC_ROOT in Makefile

3. Make sure that WEBRTC_LIB_ROOT matches the toolchain generated directory

4. make -j
