log4cplus is a C++ logging library modeled after Java's log4j API, offering thread-safe, flexible, and granular log management and configuration. It avoids heavy dependencies and supports a wide range of platforms including Linux, macOS, Windows, BSD, Android, and iOS.
Use cases
- add structured logging to a C++ application
- configure log levels and appenders at runtime
- replace printf debugging with a log4j-style logger
- log from multithreaded C++ code safely
- build a C++ library for Android or iOS with logging support
When to choose
- you want a mature log4j-like logging API in C++
- you need thread-safe logging with granular configuration
- you want minimal dependencies in a C++ project
- you target multiple platforms including mobile and BSD
When to avoid
- you need async structured logging for high-throughput services where spdlog may fit better
- your toolchain does not support C++23 required by 3.x releases
- you need logging integrated with a specific observability backend out of the box
