ox-runtime

ox-runtime is an implementation of the OpenXR Runtime specification, built for ox.

It implements the logic of an OpenXR runtime (as defined in the spec), and delegates to a driver implementation (to talk to the underlying XR hardware).

cmake -B build
cmake --build build --config Release

The build artifacts will be written under build/bin:

• ox_runtime.dll/libox_runtime.so/libox_runtime.dylib
• ox_runtime.json

cmake --build build --target runtime_tests --config Release

The runtime tests use injected mock driver bindings. They do not require the ox host process or ipc proxy.

Driver loading resolves in the following order (at runtime):

1. An already injected test driver.
2. The OX_RUNTIME_DRIVER environment variable.
3. OX_USE_SIMULATOR=1 fallback to the simulator driver (installed at ./drivers/simulator).
4. ox_ipc_client as the default driver (which connects to the ox process).
