Qt5/C++11 to Qt6/C++23 Migration Status

Last Updated: 2026-08-22 12:32
Session: 9364ea1f-2ece-4ccb-8e2d-77e7a8886a06
Branch: feature/qt6-migration-basis-modules @ c042faae

📊 Current Status

✅ BUILD_RTI=OFF Build - FIXED

Issue: RTI Connext DDS-specific libraries were being built/linked even when BUILD_RTI=OFF, causing CMake configuration failures.

Root Cause: Multiple DDS module CMakeLists.txt files had incomplete BUILD_RTI guards. Some only guarded TARGET_LINK_LIBRARIES but still tried to create libraries that depend on RTI-only components (ddsgen, ddsQoS, etc.).

Fix Applied:

Wrapped ENTIRE library definitions in IF(BUILD_RTI) guards (not just link libraries)
Removed ELSE() blocks that referenced RTI-only libraries
Fixed include path for generated export headers (angle brackets)
Fixed transitive include propagation (LtsUtilsSettings → PUBLIC)
Removed unused Qt5 legacy includes (QDesktopWidget)

Files Modified:

Lts/Common/LtsUtils/LtsUtilsSettings/settings.h - Export header include
Lts/Common/LtsWidgets/CMakeLists.txt - PUBLIC link dependency
Lts/Plugins/NmeaManagement/Gui/BatteryNotification/nme_battery_info_dialog.cpp - Remove QDesktopWidget
Lts/DDS/FTC/CMakeLists.txt - Full IF(BUILD_RTI) guards
Lts/DDS/FTS/CMakeLists.txt - Full IF(BUILD_RTI) guards, removed ELSE
Lts/DDS/DTC/CMakeLists.txt - Full IF(BUILD_RTI) guards
Lts/DDS/DTS/CMakeLists.txt - Full IF(BUILD_RTI) guards
Lts/DDS/DDSConnector/CMakeLists.txt - Full IF(BUILD_RTI) guards, removed ELSE
Lts/DDS/Routing/CMakeLists.txt - Full IF(BUILD_RTI) guards

Build Result: ✅ Configure successful, Build reached 750/888 targets (remaining failures are unrelated pre-existing code issues in BatteryNotification plugin)

📈 Migration Progress

Completed

SSH connectivity to devel host verified
Git submodule initialized and updated
Merge conflicts resolved in submodule
Git remote corrected to git@devel:lifemaps/qt6-migration-pipeline.git
Lts/Common migration complete (1/1 tests passing)
BUILD_RTI=OFF CMake configuration - FIXED
BUILD_RTI DDS module guards - COMPLETE

In Progress

BatteryNotification plugin compilation errors (pre-existing, unrelated to BUILD_RTI)
BUILD_RTI=ON build verification
Automated MIGRATION_STATUS.md update mechanism

Pending

Lts/DDS full migration review
Lts/Plugins migration (60 submodules)
Lts/Projects migration (5 submodules)
Lts/Proxies migration (13 submodules)
Lts/Services migration (47 submodules)
TetraIF completion
Z-modules completion
Full build validation
CI/CD validation

🚀 Next Steps

Fix BatteryNotification - equipmentNumber()/batteryPort() methods missing from BatteryAlarm struct
Test BUILD_RTI=ON - Verify RTI builds still work correctly
Push submodule changes - Commit c042faae to remote
Implement auto-update - Cron job or CI trigger for MIGRATION_STATUS.md
Continue module migration - Prioritize Lts/Plugins core functionality

📝 Notes

BUILD_RTI guard pattern: Wrap ENTIRE library definition, not just TARGET_LINK_LIBRARIES
Export headers from CMAKE_CURRENT_BINARY_DIR need angle bracket includes
QDesktopWidget removed in Qt6 - migrate to QScreen API or remove if unused
Submodule commits must be made separately from main repo commits
