A C++23 logging API modeled after log4j, providing thread-safe, flexible, and granular control over log management.
log4cplus is a C++ logging API that provides thread-safe, flexible, and granular control over log management and configuration. It is modeled after the Java log4j API, offering a familiar interface for C++ developers to handle logging with extensive customization options. The framework solves the problem of inconsistent or inadequate logging in C++ applications by delivering a robust, portable solution.
C++ developers building applications that require reliable, configurable logging across various platforms, including desktop, server, and embedded systems. It is particularly useful for projects needing cross-platform compatibility and fine-grained log control.
Developers choose log4cplus for its adherence to the proven log4j design, its thread safety, and its avoidance of heavy dependencies like Boost. Its support for multiple build systems and broad platform compatibility make it a versatile choice for diverse C++ environments.
log4cplus is a simple to use C++ logging API providing thread-safe, flexible, and arbitrarily granular control over log management and configuration. It is modelled after the Java log4j API.

Designed for concurrent logging with built-in thread safety, essential for modern multi-threaded C++ applications as highlighted in the README's emphasis on safe operations across threads.
Offers fine-grained control over log levels, appenders, and layouts, mimicking the mature Java log4j API for flexible log management in diverse scenarios.
Tested on Linux, Windows, BSD variants, and embedded systems like iOS, with support for multiple build systems (Autotools, CMake, Visual Studio) ensuring broad compatibility.
Includes wide character (wchar_t) support and locale-aware conversions, facilitating internationalization and handling of diverse text encodings as detailed in the configuration options.
Version 3.0 and beyond require C++23, excluding projects with older compilers or legacy codebases, as noted in the README's list of unsupported platforms.
Setup involves navigating numerous quirks, such as Windows threading deadlocks, Solaris compiler flags, and TLS issues on Android, increasing integration effort for non-standard environments.
Explicitly unsafe for use from signal handlers in threaded applications, limiting its utility in systems programming where signal-based logging is common.
Relies on Autotools as the primary build system on Unix, which can be cumbersome for developers unfamiliar with it or using alternative toolchains, despite CMake support.
