# PyPI ships ONLY a binary wheel for brainflow (no sdist), and that wheel
# bundles prebuilt native libs we must not ship. Build the pure-Python
# bindings from the GitHub source archive (python_package/) instead and
# link them to the system libs from our brainflow C++ package.

BuildRequires:  python3-devel
BuildRequires:  pyproject-rpm-macros
# Provides /usr/lib64/lib{BoardController,DataHandler,MLModule}.so so we can

Python bindings for BrainFlow, intended to obtain, parse and analyze
EEG, EMG, ECG and other kinds of data from biosensors.

Summary:        %{summary}
# The python modules dlopen the native libs at runtime (BoardController,
# DataHandler, MLModule), which the runtime brainflow package ships.

# data_filter.py, ml_model.py hardcode these paths and raise if missing).
# We do not bundle the native libs (Fedora policy) — instead symlink the
# package's lib/ entries to the system libraries from the brainflow C++
# package. Resolve to the real versioned file so the runtime dependency is
# the (versioned) brainflow package, not brainflow-devel.

# Confirm the bindings import and resolve the system native libs (the
# symlinks above + ldconfig). board_shim's loader raises FileNotFoundError
# if the lib path can't be resolved, so a clean import proves the wiring.

%changelog
* Sun Jun 14 2026 Morgan Hough <morgan.hough@gmail.com> - 5.22.2-1
- Update to 5.22.2 (current upstream; freshness sweep 2026-06-14).
- PyPI dropped the sdist (wheel-only, with bundled native libs). Switch
  Source0 to the GitHub release archive and build the pure-Python bindings
  from python_package/. Pin the CI-placeholder setup.py version.
- Symlink the package's lib/{libBoardController,libDataHandler,libMLModule}.so
  to the system libraries (resolved to their real versioned soname) instead
  of bundling: the modules dlopen these paths relative to the package.

* Wed Jan 07 2026 Morgan Hough <morgan.hough@gmail.com> - 5.19.0-1
- Initial Python bindings for BrainFlow linked against system libs
