%description
Google Logging (glog) is a C++14 library that implements application-level
logging. The library provides logging APIs based on C++-style streams and
various helper macros (LOG, VLOG, CHECK, etc.).

This package provides the shared library for glog.

%build
# 显式 out-of-source build：openEuler 24.03 LTS SP3 chroot 的 %%cmake 宏执行
# in-source configure（写到 source 目录 glog-0.7.1），但 %%cmake_build 期望
# %%_vpath_builddir 子目录（%%_target_platform=aarch64-openEuler-linux-gnu），
# 二者不一致触发 "is not a directory" 错误（build_id=113742 %%build 阶段失败）。
# 改用裸 cmake 命令显式管理 build dir，规避 chroot 宏不一致，且跨 chroot 兼容。
# !!RPM 陷阱：宏在注释行内也会被展开（必须用 %% 转义为字面 %）。
# build_id=113743 %%build 失败根因：注释中 %%cmake 被展开为完整 cmake 调用，
# 注释尾部的中文 "宏执行" 作为参数传入 cmake -> source dir "宏执行" does not exist。
# CMake 选项说明（与 CMakeLists.txt option() 一致）：
#   -DBUILD_SHARED_LIBS=ON   : 默认 ON，构建 libglog.so.*（SOVERSION=2）
#   -DWITH_GFLAGS=ON         : 启用 gflags 集成（openEuler 官方源已提供 2.2.2）
#   -DWITH_GTEST=ON          : 启用 GTest（用于 %%check 阶段的 ctest）
#   -DWITH_PKGCONFIG=ON      : 安装 libglog.pc 到 %%{_libdir}/pkgconfig/
#   -DWITH_SYMBOLIZE=ON      : 启用 symbolize 模块（默认 ON）
#   -DWITH_TLS=ON            : 启用 Thread Local Storage 支持（默认 ON）
# CMAKE_INSTALL_LIBDIR/INCLUDEDIR 显式传入，避免 GNUInstallDirs 在 aarch64
# 上推导出非标准路径（与 %%files 中 %%{_libdir}/%%{_includedir} 宏保持一致）。

%changelog
* Mon Oct 19 2026 openEuler Builder <builder@openeuler.org> - 0.7.1-3
- Escape %%-prefixed macro names in %%build section comments (%%cmake,
  %%cmake_build, %%_vpath_builddir, %%_target_platform, %%build, %%check,
  %%{_libdir}, %%{_includedir}, %%files) to prevent RPM macro expansion
  inside comments. build_id=113743 %%build failed because %%cmake in a
  comment expanded to the full cmake invocation and the trailing Chinese
  text "宏执行" was passed as a source directory argument -> "source
  directory .../宏执行 does not exist" (RPM pitfall: macros expand even
  inside comment lines).

* Mon Oct 19 2026 openEuler Builder <builder@openeuler.org> - 0.7.1-2
- Replace %%cmake/%%cmake_build/%%cmake_install/%%ctest macros with explicit
  out-of-source cmake invocation to fix "is not a directory" %%build failure
  on openeuler-24.03_LTS_SP3-aarch64 (in-source configure vs. out-of-source
  build dir mismatch in chroot cmake-rpm-macros, build_id=113742)

* Mon Oct 19 2026 openEuler Builder <builder@openeuler.org> - 0.7.1-1
- Initial package of glog 0.7.1
