%description
Connectome Workbench is an open source visualization and discovery tool used
to map neuroimaging data, especially data generated by the Human Connectome
Project.

# FIX 1: Add missing header for Fedora 43 / GCC 15+
sed -i '/#include <memory>/a #include <cstdint>' src/Common/CaretRgb.h

# FIX 2: Fix Qt5 header include
sed -i 's/#include <QtEnvironmentVariables>/#include <QtCore>/g' src/Common/WorkbenchInstallationAssistant.cxx

# FIX 3: CaretFileDialogExtendable is dead code -- its .cxx is entirely commented
# out (no implementation, so no vtable is emitted), it is used by no other source
# (only listed in GuiQt/CMakeLists), yet it is still moc'd and compiled, which
# links GuiQt against its never-emitted vtable/destructor -> undefined references.
# Drop it from the GuiQt build lists. (Keeps the real, used CaretFileDialog.)

%changelog
* Wed Jun 17 2026 Morgan Hough <morgan.hough@gmail.com> - 2.1.0-9.20260203gitf8a1b5a
- Fix FTBFS under cmake 4: bundled kloewe/dot/CMakeLists.txt declares
  cmake_minimum_required < 3.5, which cmake 4 rejects ("Compatibility with CMake
  < 3.5 has been removed"). Add -DCMAKE_POLICY_VERSION_MINIMUM=3.5. (OpenSSL/qwt
  "not found" in the log are optional and non-fatal.)
- Fix GuiQt link errors (undefined CaretFileDialogExtendable/Private vtable +
  destructor refs): CaretFileDialogExtendable is dead code -- its .cxx is fully
  commented out (no impl -> no emitted vtable) and no source uses it, but it was
  still moc'd/compiled via GuiQt/CMakeLists. Drop it from the build lists in %prep.
- Fix %%doc: top-level readme is README, not README.md.
- Use workbench's own moc switch -DWORKBENCH_USE_CMAKE_AUTOMOC=ON (single AUTOMOC
  path) instead of the bare -DCMAKE_AUTOMOC=ON layered on its manual QT5_WRAP_CPP.

* Thu Mar 19 2026 Morgan Hough <morgan.hough@gmail.com> - 2.1.0-4.20260203gitf8a1b5a
- Use %%cmake_install instead of manual find+install
- Add glib2-devel, ninja-build BuildRequires
- GCC 15 CXXFLAGS (-std=c++17 -include cstdint)
- Add wb_shortcuts, bash-completion, desktop-file-validate
- Fix icon filenames, add 32x32 icon
- Git snapshot release versioning

* Sun Jan 04 2026 Morgan Hough <morgan.hough@gmail.com> - 2.1.0-1
- Initial RPM release for Connectome Workbench v2.1.0
