LLVM is a compiler infrastructure designed for compile-time, link-time, runtime, and idle-time optimization of programs from arbitrary programming languages. It currently supports compilation of C and C++ programs, using front-ends derived from GCC 4.0.1. A new front-end for the C family of languages is in development. The compiler infrastructure includes mirror sets of programming tools as well as libraries with equivalent functionality.

Clang is a compiler front end for the C, C++, Objective-C and Objective-C++ programming languages. It uses LLVM as its back end. The Clang project includes the Clang front end, the Clang static analyzer, and several code analysis tools.

The "clang-runtime" library provides the implementations of run-time functions for C and C++ programs. It also provides header files that allow C and C++ source code to interface with the "sanitization" passes of the clang compiler. In LLVM this library is called "compiler-rt".

This package provides the run-time support library developed by the LLVM project for the OpenMP multi-theaded programming extension. This package notably provides libgomp.so, which is has a binary interface compatible with that of libgomp, the GNU Offloading and Multi Processing Library.

Spdlog is a very fast header-only/compiled C++ logging library.

Spdlog is a very fast header-only/compiled C++ logging library.

Spdlog is a very fast header-only/compiled C++ logging library.

Log4cpp is library of C++ classes for flexible logging to files, syslog, IDSA and other destinations. It is modeled after the Log4j Java library, staying as close to their API as is reasonable.

Spdlog is a very fast header-only/compiled C++ logging library.

Plog is a C++ logging library that is designed to be simple, small and flexible. It is created as an alternative to existing large libraries and provides some unique features such as CSV log format and wide string support.

MultiTail can monitor, color, filter, and merge log files and command output in multiple windows in a terminal.

This package provides a bare-bones logging library for C++, with only a printf-like syntax and five logging levels.

The log4cxx packages provides a C++ logging framework patterned after Apache log4j which uses the Apache Portable Runtime for most platform-specific code.

Google glog is a library that implements application-level logging. This library provides logging APIs based on C++-style streams and various helper macros. You can log a message by simply streaming things to log at a particular severity level. It allows logging to be controlled from the command line.

Rsyslog offers high-performance, great security features and a modular design. While it started as a regular syslogd, rsyslog has evolved into a kind of swiss army knife of logging, being able to accept inputs from a wide variety of sources, transform them, and output the results to diverse destinations.

QLogo is an interpreter for the Logo language written in C++ using Qt and OpenGL. Specifically, it mimics, as reasonably as possible, the UCBLogo interpreter.

The Lout document formatting system reads a high-level description of a document similar in style to LaTeX and produces a PostScript or plain text output file.

Lout offers an unprecedented range of advanced features, including optimal paragraph and page breaking, automatic hyphenation, PostScript EPS file inclusion and generation, equation formatting, tables, diagrams, rotation and scaling, sorted indexes, bibliographic databases, running headers and odd-even pages, automatic cross referencing, multilingual documents including hyphenation (most European languages are supported), formatting of computer programs, and much more, all ready to use. Furthermore, Lout is easily extended with definitions which are very much easier to write than troff of TeX macros because Lout is a high-level, purely functional language, the outcome of an eight-year research project that went back to the beginning.

Lsof stands for LiSt Open Files, and it does just that. It lists information about files that are open by the processes running on the system.

The cqueues extension module for Lua implements an event loop that operates through the yielding and resumption of coroutines. It is designed to be non-intrusive, composable, and embeddable within existing applications.

LuaExpat is a SAX XML parser based on the Expat library.

This package provides a FFI-based Lua API for ngx_http_lua_module or ngx_stream_lua_module.

Luamake is a platform independent configuration and build system that uses the standard Lua command-line interpreter.

LuaSQLite3 is a thin wrapper around the public domain SQLite3 database engine. It provides a complete binding to the SQLite3 C API from within Lua programs.
