%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 contains the C runtime headers, the static library
(libprotobuf-nanopb.a), the CMake integration files (nanopb-config.cmake) and
the nanopb code generator, which converts .proto definitions into .pb.c/.pb.h
source files.

# This chroot's %cmake performs an in-source build (writes Makefile into the

# %{_vpath_builddir} (aarch64-openEuler-linux-gnu) -> "is not a directory".
# %make_build / %make_install run against the in-source Makefile that %cmake
# actually generated, sidestepping the mismatched cmake-macros pair.

* Wed Sep 23 2026 openEuler Builder <builder@openeuler.org> - 0.4.9.2-2
- Fix %build: use %make_build/%make_install against %cmake in-source Makefile
(chroot's %cmake_build expects absent out-of-source dir)
* Wed Sep 23 2026 openEuler Builder <builder@openeuler.org> - 0.4.9.2-1
- Initial package for openEuler
