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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 2007: SourceForge metadata lists log4c 1.2.1 artifacts. - 2012: log4c 1.2.2 release artifacts are published on SourceForge. - 2013: log4c 1.2.3 and 1.2.4 release artifacts are published on SourceForge. ### Related projects - log4j: the Java logging library whose API and design motivated log4c. - log4cpp: the C++ logging project credited by the log4c documentation as an influence. ### Sources - - - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
