Release:        4%{?dist}
Summary:        Head tracking software for game and flight simulators

# Per OPENTRACK-LICENSING.txt the project is a collage of per-module licenses.
# The dominant licenses for the modules built on Linux (core, gui, most
# trackers/protocols/filters) are ISC and GPL-3.0-or-later (e.g. proto-ft,
# tracker-aruco wrapper). Bundled third-party code in 3rdparty-notices/
# (Aruco fork, FaceTrackNoIR, libQxt, NPClient, FreePIE, FreeTrack, etc.) is
# either ISC, BSD-2-Clause or GPL-3.0-or-later. We pick the most-restrictive
# union that covers what gets actually compiled into the binary RPM.
License:        ISC AND GPL-3.0-or-later AND BSD-2-Clause AND BSD-3-Clause

# Bundled libraries shipped in the binary RPM. qxt-mini is vendored
# under qxt-mini/ in the upstream source tree; its license (BSD-3-Clause)
# is already covered by the License: expression above.
Provides:       bundled(qxt-mini)

%description
opentrack tracks head motion in space and broadcasts position and rotation to
flight and racing simulators. It supports a wide variety of input devices
(webcams, IR-LED point trackers, Arduino hardware, gamepads, IMUs) and output
protocols (freetrack, TrackIR/NPClient, UDP, joystick, X-Plane plugin, etc).

Tracking modules and protocols are loaded as plugins from
%{_libexecdir}/opentrack/. Several modules included in upstream require
proprietary SDKs (Tobii, RealSense, Kinect SDK, Oculus libOVR, Razer Hydra,
TrackHat) or the opentrack Aruco fork; those are omitted from this build.

%changelog
* Wed Jun 03 2026 Morgan Hough <morgan.hough@gmail.com> - 2026.1.0-4
- Strip Windows-only contrib payloads from %%{_docdir}/opentrack/contrib/
  (Tir4Fun/npclient.dll, trackir-client/client.exe) — Fedora policy bans
  shipping precompiled foreign binaries. Claim the remaining contrib
  files (FlightGear/headtracker.xml + readme.txt) under %%doc.
  Build 10562329 failed with 'Installed (but unpackaged) file(s)'.

* Wed Jun 03 2026 Morgan Hough <morgan.hough@gmail.com> - 2026.1.0-3
- Add pkgconfig(libproc2) BuildRequires. Build 10561394 failed at
  cmake configure: compat/CMakeLists.txt:21 demands libproc2 or
  libprocps for process enumeration on Linux.

* Wed Jun 03 2026 Morgan Hough <morgan.hough@gmail.com> - 2026.1.0-2
- Add Provides: bundled(qxt-mini). qxt-mini is vendored under qxt-mini/
  in the upstream source tree and shipped in the binary RPM; Fedora
  packaging policy requires an explicit bundled() Provides for every
  bundled library. License (BSD-3-Clause) is already covered by the
  existing License: expression.

* Wed Jun 03 2026 Morgan Hough <morgan.hough@gmail.com> - 2026.1.0-1
- Initial package for opentrack 2026.1.0
