GNU's C Library
The GNU C library is used as the C library in the GNU system and most newer systems with the Linux kernel. The history of Unix and various standards determine much of the interface of the C library. In general the GNU C library supports the ISO C and POSIX standards. We also try to support the features of popular Unix variants (including BSD and System V) when those do not conflict with the standards. Different compatibility modes (selectable when you compile an application) allow the peaceful coexistence of compatibility support for different varieties of Unix. hot
Any Unix-like operating system needs a C library: the library which defines the ``system calls'' and other basic facilities such as open, malloc, printf, exit. The GNU C library is used as the C library in the GNU system and most systems with the Linux kernel. hot
STMX is a high-performance Common Lisp library for composable Software Transactional Memory (STM), a concurrency control mechanism aimed at making concurrent programming easier to write and understand new
The 2DECOMP&FFT library is a software framework in Fortran to build large-scale parallel applications.
A'Hote is a C++ library for creating color schemes including complements, split complements, triadics, tetradics, analogous colors, monochromatic groups, shaded groups, and tinted groups. The color scheme generators are also overloaded, allowing schemes of schemes to be generated. There are functions for converting RGB, HSB, HSL, YUV, and RYB.

ABL (Atoku's Basic List) is a flexible abstract list library defined using the C preprocessor. It allows you to define linked lists of arbitrary types very easily.
a platform independent library for generating distributed server-based components and applications
Active Objects is an implementation of the Active Object concept based on the boost::thread, boost::bind, and boost::function libraries. The point of the library is to make taking advantage of multiprocessor machines as easy as possible.
Adobe Source Libraries
The Adobe Source Libraries (ASL) are a collection of C++ libraries building foundation technology to allow the construction of commercial applications by assembling generic algorithms through declarative descriptions.

a C library
Bmrblib is an API abstracting the BioMagResBank (BMRB) NMR-STAR format. It allows the writing of NMR-STAR files for BMRB data deposition and the reading and easy extraction of data from files residing in the BMRB data bank, all without knowledge of the Self-Defining Text Archive and Retrieval (STAR) format. The API has currently only python bindings.
BPS implements a B-tree with a twist pointer set, which approaches the speed of the fastest, hash table based sets, while using several times less memory and still maintaining order.
BS is a data structures library. It features fixed data size, random access sequences.
C Algorithms Library
C Algorithms Library is a collection of commonly used Computer Science algorithms. The focus is on code that is well documented and tested, portable, and reusable.
C Generic Library
The C Generic Library is a collection of data structures designed and created in as generic a fashion as possible. Each data structure will contain its own basic memory management, be able to handle any object type, and hopefully constrain to strict algorithmic constraints. It contains doubly linked list, vector, deque, stack, queue, and binary tree structures, with list and vector based versions available for deque, stack, and queue.
C++ Machine Objects
The Machine Objects class library (in short Macho) supports a subset of the UML statechart notation for implementing hierarchical state machines in straight C++, similar in spirit to the GoF "State" design pattern.
a C++ library which can be used to pool resources of
every kind. One very interesting side effect is that it can also be used of abstraction layer by providing a unique API for different resources of similar resource types
C++ Sockets is a GPL licensed C++ class library wrapping the berkeley sockets C API, and therefore works on most unixes and also win32.
C++ WSDL Parser
C++ WSDL Parser is a C++ WSDL library which includes a WSDL parser, XML Parser and Serializer,Schema parser and Validator and an API to dynamically inspect and invoke a WSDL web service.
a C++ wrapper for the SANE library
Caches.rb is a simple method caching library.
CacheTable is a C++ template library that implements a very fast hash map container.
CarvPath (libcarvpath) is a library aimed at computer forensic tools that process disk and/or memory dump images or other large data files.
Cawfee CGI SDK
designed to retrieve the CGI input from the web server and parse it so that programs can use it.
