Lts/Viewer Module Qt6 Migration Status Report

Executive Summary

The Lts/Viewer module migration infrastructure has been successfully configured. The build system now supports building and testing all 7 Viewer module targets with mandatory BUILD_RTI=ON and BUILD_GRANTLEE=ON variants.

Migration Scope

Module: Lts/Viewer

• Qt5 Legacy: ./qt-migration-legatus/qt5-before/qt5-legatus-legacy/Lts/Viewer
• Qt6 Target: ./qt-migration-legatus/qt6-after/qt6-migrated-legatus/Lts/Viewer
• Target Branch: feature/migrate-lts-viewer.md

CMake Targets Configured

The following 7 targets are now configured in new_docker_build.sh under GROUP5:

1. situationMapCommon - Common SituationMap utilities
2. advancedSymbology - Advanced symbology rendering
3. advancedSymbologyXML - XML-based symbology
4. advancedSymbologyXML_Gui - GUI components for XML symbology
5. LtsDataView - Data visualization component (BUILD_RTI conditional)
6. LtsFileDialog - File dialog utilities
7. LtsReportDisplay - Report display component

Changes Made

1. Build Script Updates (new_docker_build.sh)

Added GROUP5 Configuration:

• --group5/--no-group5 command-line option
• BUILD_GROUP5 environment variable support
• GROUP5_TARGETS array with all 7 Viewer targets
• Help text documentation

Added BUILD_GRANTLEE Support:

• --grantlee/--no-grantlee command-line option
• BUILD_GRANTLEE environment variable (default: ON)
• CMake invocation with -DBUILD_GRANTLEE flag
• Container script defaults

Bug Fixes:

• Fixed duplicate BUILD_GROUP4=OFF default in container script section

2. CTest Integration

LtsDataView/CMakeLists.txt:

if(BUILD_TESTING)
    add_test(NAME LtsDataViewTest COMMAND $<TARGET_FILE:LtsDataViewTest>)
endif()

LtsFileDialog/CMakeLists.txt:

if(BUILD_TESTING)
    add_test(NAME LtsFileDialogTest COMMAND $<TARGET_FILE:LtsFileDialogTest>)
endif()

Note: LtsReportDisplay has no test executable defined in CMakeLists.txt.

3. SituationMap Reorganization

Significant pruning occurred in Qt6 migration:

• Qt5: 30 subdirectories, 524 files
• Qt6: 5 subdirectories, 136 files

Active in Qt6:

• Common/
• SymbologyXML/
• Symbology/

Commented out in Qt6 CMakeLists.txt:

• Map/
• SymbologyImpl/
• 20+ other subdirectories (intentionally removed per commit 92ad7d468)

Build Configuration

Mandatory Variants (ON only)

• BUILD_RTI=ON ✓
• BUILD_GRANTLEE=ON ✓

Forbidden Variants (not implemented)

• BUILD_RTI=OFF ✗
• BUILD_GRANTLEE=OFF ✗

Docker Validation Command

cd qt-migration-legatus/qt6-after/qt6-migrated-legatus
BUILD_RTI=ON BUILD_GRANTLEE=ON ./new_docker_build.sh --group5

Direct CMake Build Command

cmake -S qt-migration-legatus/qt6-after/qt6-migrated-legatus \
      -B build-rti-on-grantlee-on \
      -G Ninja \
      -DCMAKE_BUILD_TYPE=Debug \
      -DBUILD_RTI=ON \
      -DBUILD_GRANTLEE=ON
cmake --build build-rti-on-grantlee-on --parallel
ctest --test-dir build-rti-on-grantlee-on --output-on-failure

Preservation Rules Verified

✓ Module removals preserved (commit 92ad7d468)

• SituationMap subdirectories intentionally removed
• No attempts to restore removed modules

✓ LogViewer reinsert preserved (commit 1fa789767)

• LogViewer remains in build configuration

✓ IDL warning fixes preserved (commit be912de9d)

• No duplicate enum definitions
• No builtin-type collisions

Qt5 API Deprecations

Found in Qt5 tree only (not present in Qt6):

• QDesktopWidget → Should use QScreen in Qt6
• QRegExp → Should use QRegularExpression in Qt6

Locations in Qt5:

• SituationMap/EvalApps/
• SituationMap/Tests/
• SituationMap/Symbology/
• SituationMap/SymbologyImpl/

Qt6 tree: No occurrences found - already migrated.

Forward Declarations

Location: qt6-after/qt6-migrated-legatus/forward-declarations/

Viewer-related files:

• map_dtc.h - SituationMap::Dds::Dtc forward declaration
• map_ftc.h - SituationMap::Dds::Ftc forward declaration

Status: Properly located in allowed directory, not in service directories.

Code Generation

BUILD_GRANTLEE Integration:

• Root CMakeLists.txt line 163: option(BUILD_GRANTLEE "Enable Grantlee/KTextTemplate code generation" ON)
• cmake/MacroCodeGenIdl.cmake: Uses BUILD_GRANTLEE to conditionally skip SQL generation
• Forward declaration stubs allow compilation when BUILD_GRANTLEE=OFF (not validated per migration rules)

Generated Files:

• No generated files committed to source tree ✓
• Build tree generation configured via CMake macros ✓

External Dependencies

Required for Docker builds:

• ./external/ArcGIS
• ./external/GeographicLib
• ./external/rti_connext_dds-7.7.0
• ./rti_license.dat (mounted read-only)

Validation Status

Completed ✓

• Repository state inspection
• Branch verification (feature/migrate-lts-viewer.md)
• Migration prompt requirements analysis
• Qt5 vs Qt6 directory structure comparison
• Source file inventory (524→136 files in SituationMap)
• Qt5 API usage pattern identification
• BUILD_RTI conditional verification (already present)
• BUILD_GRANTLEE option verification
• GROUP5 configuration added to new_docker_build.sh
• BUILD_GRANTLEE support added to build script
• Duplicate BUILD_GROUP4 default fixed
• Bash syntax validation passed
• Help output tested
• CTest registration for LtsDataViewTest
• CTest registration for LtsFileDialogTest
• Git commit created

Pending

• Docker build validation with --group5 option
• CTest execution in Docker container
• Jenkins/policy compatibility verification
• Full source file migration review (beyond initial grep)
• BUILD_GRANTLEE usage verification in all Viewer CMakeLists.txt files

Known Issues

None identified at this stage. The migration infrastructure is configured and ready for validation builds.

Next Steps

1. Docker Validation Build

   cd qt-migration-legatus/qt6-after/qt6-migrated-legatus
   BUILD_RTI=ON BUILD_GRANTLEE=ON ./new_docker_build.sh --group5
   

2. CTest Execution

   • Verify LtsDataViewTest runs successfully
   • Verify LtsFileDialogTest runs successfully
   • Check test output for any failures

3. Jenkins Compatibility

   • Verify ci/check_pr_policies.py accepts new test names
   • Check ci/Dockerfile.* for any required updates

4. Source File Review

   • Deep inspection of SituationMap subdirectories
   • Verify all Qt5→Qt6 API migrations are complete
   • Check for any remaining deprecated API usage
