Building

Server (PC)

Dependencies

WiVRn requires avahi-client, eigen3, libpulse, libsystemd, nlohmann_json.

It also requires at least one encoder:

  • For vaapi (AMD/Intel), it requires ffmpeg with vaapi and libdrm support, as well as vaapi drivers for the GPU
  • For nvenc (Nvidia), it requires cuda and nvidia driver
  • For x264 (software encoding), it requires libx264

Some distributions such as Fedora don't ship h264 and h265 encoders and need specific repositories.

Compile

From your checkout directory, with automatic detection of encoders

cmake -B build-server . -GNinja -DWIVRN_BUILD_CLIENT=OFF -DCMAKE_BUILD_TYPE=RelWithDebInfo
cmake --build build-server

It is possible to force specific encoders, by adding options

-DWIVRN_USE_VAAPI=ON
-DWIVRN_USE_X264=ON
-DWIVRN_USE_NVENC=ON

Additionally, if your environment requires absolute paths inside the OpenXR runtime manifest, you can add -DWIVRN_OPENXR_INSTALL_ABSOLUTE_RUNTIME_PATH=ON to the build configuration.

Client (headset)

Build dependencies

As Arch package names: git git-lfs pkgconf glslang cmake jre17-openjdk librsvg

Android environment

Download sdkmanager commandline tool and extract it to any directory. Create your ANDROID_HOME directory, for instance ~/Android.

Review and accept the licenses with

sdkmanager --sdk_root="${HOME}/Android" --licenses

Client build

For Pico only: setup git lfs

From the main directory.

export ANDROID_HOME=~/Android
export JAVA_HOME=/usr/lib/jvm/openjdk-bin-17/

./gradlew assembleStandardRelease
# Or for Pico assemblePico

Outputs will be in build/outputs/apk/standard/release/WiVRn-standard-release-unsigned.apk
