historique
Historique du projet et usages
log4c is a C logging framework modeled after Apache log4j, intended to bring category-based logging, appenders, layouts, and runtime configuration to C programs that need flexible output to files, syslog, or other destinations.
Historique du projet
The official documentation describes log4c as a SourceForge-hosted C library that stayed close to the log4j API where practical while adapting the design to C. Its documentation also credits earlier and parallel C logging work, including Mark Mendel's macro-oriented log4c project and Bastiaan Bakker's log4cpp as influences.
SourceForge release metadata shows a long 1.0.x line in the 2000s, a 1.2.1 release in 2007, and later maintenance releases through 1.2.4 in October 2013. The 1.2.4 documentation still presents an autotools build and an XML-style log4crc configuration file.
Historique d'adoption
log4c became a package-manager-visible C logging dependency rather than a large end-user command. The supplied package metadata records packaging in Homebrew, Debian and Ubuntu as liblog4c-dev, Fedora/DNF, MacPorts, and openSUSE/Zypper, which is the main adoption signal for a small C library of this vintage.
Its official platform list covers several Unix systems, including HP-UX, AIX, FreeBSD, Solaris, macOS-era Darwin, and multiple Linux distributions, reflecting the portability expectations of C infrastructure libraries.
Modes d'utilisation
Programs link against log4c and configure categories, appenders, and layouts with a log4crc XML file. The documented search order is `${LOG4C_RCPATH}/log4crc`, then `${HOME}/.log4crc`, then `./log4crc`, with environment variables also available for root priority and appender selection.
Package users mostly encounter log4c through development packages, headers, libraries, generated Doxygen documentation, pkg-config or log4c-config metadata, and build scripts that need a C logging backend.
Pourquoi les passionnés de paquets s'y intéressent
log4c is a classic example of the early-2000s log4j pattern spreading into native-language package ecosystems. For package maintainers it matters less as a flashy CLI and more as a small ABI-bearing C library with autotools metadata, distro patches, and reverse dependencies that expect stable headers and linker flags.
