# Upstream currently publishes and tests Linux VR release artifacts primarily on x86_64.
ExclusiveArch:  x86_64

# WayVR's ovr_overlay dependency links against its pinned vendored OpenVR
# library. Keep that exact runtime library private to WayVR instead of
# replacing it with Fedora's newer system OpenVR ABI.

%description
WayVR is a lightweight OpenXR/OpenVR overlay that provides access to Wayland
and X11 desktops from Monado, WiVRn, or SteamVR. It also includes wayvrctl for
controlling a running WayVR instance from the command line.

# The release asset is generated by upstream with `cargo vendor` and includes

# Embed the private OpenVR search path while linking.  Using patchelf here
# corrupts this large PIE's program header table on Fedora, leaving it with no
# PT_LOAD segments and making it segfault immediately at its entry point.
