# topdir: libnanopb-dev-0.4.9.2 (set by --transform in build driver)
# Self-provision note: cmake(Nanopb)/cmake(nanopb) is PROVIDED by this package
# (via extra/nanopb-config.cmake installed to %%{_libdir}/cmake/nanopb/), NOT required.
# The find_package(Nanopb) calls in source exist only in extra/FindNanopb.cmake
# (the find-module this package ships for consumers), build-tests/ and examples/

# Disable debuginfo subpackage: this package ships only a static library
# (libprotobuf-nanopb.a), header files, CMake config files and Python scripts.
# There are no ELF executables or shared libraries, so find-debuginfo produces
# an empty debugfiles.list and rpmbuild fails with "Empty %files file".

%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
