%description
Nanopb is a small code-size Protocol Buffers implementation in ANSI C. It is
especially suitable for use in microcontrollers, but fits any memory
restricted system.

This package provides the C runtime static library (libprotobuf-nanopb.a),
header files, CMake integration files, and the Python-based code generator
(protoc plugin) used to compile .proto definitions into nanopb C source.

%changelog
* Mon Sep 28 2026 openEuler Builder <builder@openeuler.org> - 0.4.9.2-3
- Disable debuginfo subpackage via %%global debug_package %%{nil}
  (package ships only static lib + Python scripts + headers, no ELF binaries
  => find-debuginfo produces empty debugfiles.list => "Empty %%files file")

* Mon Sep 28 2026 openEuler Builder <builder@openeuler.org> - 0.4.9.2-2
- Fix %build: replace %cmake_build/%cmake_install with %make_build/%make_install
  (%cmake macro runs in-place but %cmake_build expects %{_target_platform} dir)
- Add %{_bindir}/nanopb_generator.py to %files (installed by cmake, was missing)

* Mon Sep 28 2026 openEuler Builder <builder@openeuler.org> - 0.4.9.2-1
- Initial package
