CMPH - C Minimal Perfect Hashing Library A perfect hash function maps a static set of n keys into a set of m integer numbers without collisions, where m is greater than or equal to n. If m is equal to n, the function is called minimal. Minimal perfect hash functions are widely used for memory efficient storage and fast retrieval of items from static sets, such as words in natural languages, reserved words in programming languages or interactive systems, universal resource locations (URLs) in Web search engines, or item sets in data mining techniques. Therefore, there are applications for minimal perfect hash functions in information retrieval systems, database systems, language translation systems, electronic commerce systems, compilers, operating systems, among others.

Coccinelle is a program matching and transformation engine which provides the language SmPL (Semantic Patch Language) for specifying desired matches and transformations in C code. Coccinelle was initially targeted towards performing collateral evolutions in Linux. Such evolutions comprise the changes that are needed in client code in response to evolutions in library APIs, and may include modifications such as renaming a function, adding a function argument whose value is somehow context-dependent, and reorganizing a data structure. Beyond collateral evolutions, Coccinelle is successfully used (by us and others) for finding and fixing bugs in systems code.

Code::Blocks is an open source, cross-platform and free C/C++ IDE. It is build using the wxWidgets GUI library. The WEB site states: "Code::Blocks is a free C++ IDE built specifically to meet the most demanding needs of its users. It was designed, right from the start, to be extensible and configurable." LICENSE: GPL3 or later (IDE) LICENSE: LGPL3 or later (SDK)

Boost provides free peer-reviewed portable C++ source libraries. The emphasis is on libraries that work well with the C++ Standard Library. Boost libraries are intended to be widely useful, and usable across a broad spectrum of applications. The Boost license encourages both commercial and non-commercial use. The goal is to establish "existing practice" and provide reference implementations so that Boost libraries are suitable for eventual standardization. Ten Boost libraries are already included in the C++ Standards Committee's Library Technical Report (TR1) and will be in the new C++0x Standard now being finalized. C++0x will also include several more Boost libraries in addition to those from TR1. More Boost libraries are proposed for TR2.

Boost.Jam (BJam) is a build tool based on FTJam, which in turn is based on Perforce Jam. It contains significant improvements made to facilitate its use in the Boost Build System, but should be backward compatible with Perforce Jam.

Concurrency Kit provides a plethora of concurrency primitives, safe memory reclamation mechanisms and non-blocking data structures designed to aid in the design and implementation of high performance concurrent systems.

BSDBuild is a simple, self-contained and portable build system derived from the traditional 4.4BSD share/mk files. BSDBuild uses BSD-style makefiles, but without BSD make extensions (it uses standard Bourne script fragments instead), so the build system is portable to most operating systems and make flavors. Because BSDBuild is implemented as a library, Makefiles never need to be recompiled (unless a separate build is requested). BSDBuild can also generate pure Bourne ./configure scripts, which function similarly to GNU-style configure scripts (as far as end-users are concerned), but are compiled using Perl modules instead of macro packages.

CppTest is a portable and powerful, yet simple, unit testing framework for handling automated tests in C++. The focus lies on usability and extendability. Several output formats, including simple text output, compiler-like output and HTML, are supported and new ones are easily added.

This is the library to allow connections to an Monetra Payment Processing Daemon via SSL and TCP/IP. It is the base of other APIs including PHP, PERL, and JAVA.
