%description
Qt 5.15.1 built from the O3DE (Open 3D Engine) fork. This includes custom
patches for high-DPI scaling, performance, and platform fixes applied to
qtbase and qtimageformats. The other modules (qtgraphicaleffects, qtsvg,
qttools, qtx11extras, qtwayland) are upstream Qt 5.15.1.

This package provides the shared libraries and plugins needed at runtime.

%description    devel
Header files, CMake config files, mkspecs, and development tools (moc, uic,
rcc, qmake, lrelease, lupdate) for the O3DE fork of Qt 5.15.1.

# GCC 15 removed transitive includes that Qt 5.15.1 relies on.
# qfloat16.h, qendian.h, qbytearraymatcher.h, and others use

# included by everything) so all files get them transitively.

%changelog
* Thu Feb 12 2026 O3DE Package Maintainers <noreply@o3de.org> - 5.15.1-7
- Ignore qtwayland compositor install errors (missing qt-texture-sharing
  protocol header; O3DE only needs the client QPA plugin)
- Remove -system-tiff (tiff is handled by qtimageformats, not qtbase)

* Thu Feb 12 2026 O3DE Package Maintainers <noreply@o3de.org> - 5.15.1-5
- Fix configure options: use -no-feature-{vnc,linuxfb,renameat2,getentropy,statx}
  syntax (shortcut forms not available in Qt 5.15.1)
- Fix GCC 15 missing transitive includes: add #include <limits> and
  #include <cstdint> to qglobal.h (the master Qt header)
- Suppress -Wtemplate-body diagnostics via CXXFLAGS
- Add perl-English BuildRequires (split from perl-interpreter in Fedora 43)

* Thu Feb 12 2026 O3DE Package Maintainers <noreply@o3de.org> - 5.15.1-1
- Initial package of O3DE's forked Qt 5.15.1
- Builds qtbase, qtgraphicaleffects, qtimageformats, qtsvg, qttools,
  qtx11extras, qtwayland
- Installs to /opt/o3de/qt5 to avoid conflicts with system Qt5
- Includes O3DE's custom patches for high-DPI scaling and platform fixes
