Detailed Description

System module integration flags.

This file provides KCENON_* macros for detecting and controlling integration with other system modules (thread_system, logger_system, etc.). These flags are typically set via CMake and propagated as compile definitions.

Integration flags:

• KCENON_WITH_THREAD_SYSTEM
• KCENON_WITH_LOGGER_SYSTEM
• KCENON_WITH_MONITORING_SYSTEM
• KCENON_WITH_CONTAINER_SYSTEM
• KCENON_WITH_NETWORK_SYSTEM
• KCENON_WITH_DATABASE_SYSTEM
• KCENON_WITH_MESSAGING_SYSTEM

Note

These macros are designed to be set via CMake's target_compile_definitions() or features.cmake configuration.

KCENON_WITH_COMMON_SYSTEM

#define KCENON_WITH_COMMON_SYSTEM   1

Indicates that common_system types are available.

When feature_flags.h is included, this macro is automatically defined to 1. Downstream projects (e.g., network_system) can use this to detect whether common_system types like kcenon::common::Result<T> are available.

This prevents ABI incompatibility issues where:

• Project A includes common_system headers and expects kcenon::common::Result<T>
• Project B is built without the flag and uses a local fallback type
• Linking causes symbol mismatches or heap corruption

Note

This flag is always set to 1 when feature_flags.h is included. It is not configurable since including this header implies common_system is available.

#ifdef KCENON_WITH_COMMON_SYSTEM
    using result_type = kcenon::common::Result<T>;
#else
    using result_type = local::Result<T>;  // fallback
#endif
