# ---------------------------------------------------------
# FIX 1: API Mismatch - Rename dtkCoreObjectManager -> dtkObjectManager
# ---------------------------------------------------------
sed -i 's/dtkCoreObjectManager/dtkObjectManager/g' src/dtkImagingCore/dtkImaging.cpp

# ---------------------------------------------------------
# FIX 2: Header Include Style
# ---------------------------------------------------------
# Replace the missing specific header with the module header
grep -rl "#include <dtkWidgetsWidget>" . | xargs sed -i 's|#include <dtkWidgetsWidget>|#include <dtkWidgets>|g'

# ---------------------------------------------------------
# FIX 3: Forwarding Header for xarray.hpp
# ---------------------------------------------------------
mkdir -p local_include/xtensor
echo '#include "xtensor/containers/xarray.hpp"' > local_include/xtensor/xarray.hpp

# ---------------------------------------------------------
# FIX 4: Shadow broken system dtkWidgets header
# ---------------------------------------------------------
mkdir -p local_include/dtkWidgets
cp /usr/include/dtkWidgets/dtkWidgets local_include/dtkWidgets/
sed -i '/dtkDistributedGuiApplication.h/d' local_include/dtkWidgets/dtkWidgets

# ---------------------------------------------------------
# FIX 5: Rename Missing Class (dtkWidgetsWidget -> QWidget)
# ---------------------------------------------------------
# The class dtkWidgetsWidget was removed in dtk 1.7.1. 
# We assume it was just a wrapper around QWidget.
grep -rl "dtkWidgetsWidget" src | xargs sed -i 's/dtkWidgetsWidget/QWidget/g'

# We add -I.../local_include/dtkWidgets so the compiler finds our patched "dtkWidgets" 
# header before looking in /usr/include.

%changelog
* Sun Aug 23 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-2
- Rebuild against VTK 9.7.0. VTK here installs unversioned sonames
  (libvtk*.so.1), so 9.7 replaces 9.6 in place and every consumer must be
  rebuilt or it fails at runtime with undefined symbols.

* Tue Jan 06 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-1
- Fix API mismatch, include paths, and broken system headers
