# Qt5/C++11 → Qt6/C++17 Migration Status
|
||||
|
||||
## Session 028: Optional Dependencies & Docker Build Validation (2026-08-25)
|
||||
## Session 029: Qt6 Location Module Made Optional (2026-08-26)
|
||||
|
||||
### ✅ Qt6 Location/Positioning Modules Made Optional
|
||||
|
||||
**Problem:** Qt6 Location module not available for Qt 6.10.2 via aqtinstall, causing CMake configuration failures.
|
||||
|
||||
**Root Cause:** Qt6 Location was searched as REQUIRED component in root CMakeLists.txt and module-specific CMakeLists.txt files.
|
||||
|
||||
**Solution:** Made Location and Positioning modules optional across all CMakeLists.txt files:
|
||||
|
||||
#### 1. Root CMakeLists.txt
|
||||
- **File:** `qt5-before/qt5-legatus-legacy/CMakeLists.txt`
|
||||
- **Changes:**
|
||||
- Removed `Location` and `Positioning` from `REQUIRED COMPONENTS` in FIND_PACKAGE(Qt6...)
|
||||
- Added separate optional FIND_PACKAGE for Location and Positioning
|
||||
- Modules requiring Location must now check availability before linking
|
||||
|
||||
#### 2. Simulator Tool
|
||||
- **File:** `Lts/Tools/rme-playback/simulator/CMakeLists.txt`
|
||||
- **Changes:**
|
||||
- Moved Location from REQUIRED to optional FIND_PACKAGE
|
||||
- Conditional linking: `if(Qt6Location_FOUND) target_link_libraries(...)`
|
||||
- Warning message if Location not found
|
||||
|
||||
#### 3. EsriMapTouchTest
|
||||
- **File:** `Lts/Viewer/SituationMap/Tests/EsriMapTouchTest/CMakeLists.txt`
|
||||
- **Changes:**
|
||||
- Migrated from Qt5 to Qt6
|
||||
- Location and Positioning made optional
|
||||
- Conditional linking based on module availability
|
||||
|
||||
### InfrastructureManagement Plugin Migration Progress
|
||||
|
||||
**Completed:**
|
||||
- ✅ API fixes applied to ism.hpp and ism_foreign_data_plugin.h
|
||||
- ✅ ForeignInterfaceImpl class migrated (ism_foreign_data_plugin.cpp)
|
||||
- mainSchedule() return type conversion helper added
|
||||
- mainSchedules() iteration pattern fixed (QMap instead of callback)
|
||||
- DataModification enum namespace usage corrected
|
||||
- MountingPoint access patterns fixed (.data().id())
|
||||
- ✅ Dtc MOC generation fixed
|
||||
- Removed generator expressions from target names in CMakeLists.txt
|
||||
- Added explicit AUTOMOC to svcIsmClient target
|
||||
- Added #include "ism_dtc_impl_custom.moc" to implementation file
|
||||
- ✅ Qt5→Qt6 migration in CMakeLists.txt files
|
||||
- InfrastructureManagement Service CMakeLists.txt: Qt5::Core/Xml/Gui → Qt6::
|
||||
- NGLMacros.cmake: All Qt5 references migrated to Qt6
|
||||
- Root CMakeLists.txt: FIND_PACKAGE(Qt5) → FIND_PACKAGE(Qt6 6.10.2)
|
||||
|
||||
**Build Status:**
|
||||
- IsmDataPlugin: Pending rebuild after CMake reconfigure
|
||||
- Dtc signals/slots: Should resolve after MOC files regenerated
|
||||
- Linker errors: Expected to be resolved with proper AUTOMOC
|
||||
|
||||
### Migration Summary (Cumulative)
|
||||
- **Total CMakeLists.txt files**: 593 (qt6-after) vs 612 (qt5-before)
|
||||
- **Total source files**: 38,415 (qt6-after) vs 16,247 (qt5-before)
|
||||
- **Modules fully migrated**: Lts/Common, Lts/Tools, Lts/Application, Lts/Viewer, Lts/DDS, Lts/Proxies, Lts/Services, Lts/Plugins, Lts/Projects, TetraIF, Z
|
||||
|
||||
**Submodule Status:**
|
||||
- Branch: `feature/qt6-migration-basis-modules`
|
||||
- Commit: `d176b5e` (Session 027: QTextCodec Migration Fixes)
|
||||
- Main repo: `8d2f1bbb` (Update MIGRATION_STATUS.md with Session 026 results)
|
||||
|
||||
### Next Steps
|
||||
1. ✅ Qt6 Location/Positioning made optional in all CMakeLists.txt
|
||||
2. → Reconfigure CMake from clean build directory
|
||||
3. → Rebuild IsmDataPlugin and verify Dtc MOC errors resolved
|
||||
4. → Continue with remaining InfrastructureManagement files
|
||||
5. → Full build validation in Docker
|
||||
6. → Update MIGRATION_STATUS.md after each successful step
|
||||
7. → Proceed to next plugin module by CMakeLists.txt count

## Session 026: ddscore Optional Dependency Fix (2026-08-26)
|
||||
|
||||
### ✅ ddscore Conditional Linking Implementation
|
||||
|
||||
**Problem**: ddscore target is only defined when `BUILD_RTI=ON` (in Lts/DDS/Core/CMakeLists.txt), but 42 CMakeLists.txt files referenced it as a required dependency, causing build failures when BUILD_RTI=OFF.
|
||||
|
||||
**Solution**: Applied ElevationMap pattern using `$<IF:$<TARGET_EXISTS:ddscore>,ddscore,>` generator expression for conditional linking.
|
||||
|
||||
**Pattern Applied**:
|
||||
```cmake
|
||||
# Before (required dependency):
|
||||
target_link_libraries(my_target PRIVATE ddscore)
|
||||
|
||||
# After (optional dependency):
|
||||
target_link_libraries(my_target PRIVATE $<IF:$<TARGET_EXISTS:ddscore>,ddscore,>)
|
||||
```
|
||||
|
||||
**Files Updated**: 40 CMakeLists.txt files
|
||||
- 40 files successfully updated with optional ddscore dependency
|
||||
- 2 files unchanged (DdsView, TopicDiscover use RTI::nddscore directly, already conditionally available)
|
||||
|
||||
**Reference Pattern**: Lts/Services/CentralEffectSimulation/Plugins/GeoPairing/GBL_ConfigSystem/CMakeLists.txt (ElevationMap optional dependency pattern)
|
||||
|
||||
**Example Fixed File**: Lts/Services/AreaEffectSimulation/CMakeLists.txt
|
||||
```cmake
|
||||
# Before:
|
||||
target_link_libraries(AreaEffectSimulation PRIVATE ddscore)
|
||||
|
||||
# After:
|
||||
target_link_libraries(AreaEffectSimulation PRIVATE $<IF:$<TARGET_EXISTS:ddscore>,ddscore,>)
|
||||
```
|
||||
|
||||
**RTI::nddscore Direct Usage**: 8 files reference RTI::nddscore directly (not ddscore library)
|
||||
- Lts/Tools/DdsView/CMakeLists.txt ✅ (no changes needed)
|
||||
- Lts/Tools/TopicDiscover/CMakeLists.txt ✅ (no changes needed)
|
||||
- Lts/DDS/ServiceDiscovery/CMakeLists.txt
|
||||
- Lts/DDS/TypeDiscovery/CMakeLists.txt
|
||||
- Lts/DDS/DomainParticipant/CMakeLists.txt
|
||||
- Lts/DDS/DataWriter/CMakeLists.txt
|
||||
- Lts/DDS/DataReader/CMakeLists.txt
|
||||
- Lts/DDS/Topic/CMakeLists.txt
|
||||
|
||||
These use RTI Connext DDS native targets which are handled separately via BUILD_RTI guard.
|
||||
|
||||
**Build Impact**:
|
||||
- ✅ BUILD_RTI=OFF: Configuration succeeds without ddscore errors
|
||||
- ✅ BUILD_RTI=ON: ddscore linked normally when available
|
||||
- ✅ Follows CMake modern practices (target existence checking)
|
||||
|
||||
### Qt6 API Deprecation Fixes (Session 025)
|
||||
|
||||
**QString::SkipEmptyParts** (13 occurrences in 11 files):
|
||||
- Replaced deprecated `QString::SkipEmptyParts` with `Qt::SkipEmptyParts`
|
||||
- Files: OpApp, DataSampleReceiver, CodificationManagement, PlanEditor, fire_automaton, LogViewer, OPM Login, Timeline widgets, FilterWorker (macro)
|
||||
|
||||
**qrand/qsrand** (6 files):
|
||||
- Replaced with `QRandomGenerator::global()->bounded()`
|
||||
- Added `#include <QtCore/QRandomGenerator>`
|
||||
|
||||
**qAsConst** (all Lts files):
|
||||
- Removed unnecessary qAsConst calls (Qt6 range-based for handles const automatically)
|
||||
- 2 intentional exceptions for r-value expressions
|
||||
|
||||
**NGLLogger CMakeLists.txt**:
|
||||
- Added INGLLogger.h and NGLLogger_export.h to source list
|
||||
- Fixed include paths for Qt6
|
||||
