Open Source C++ Libraries for Windows

Dlib is a C++ toolkit containing machine learning algorithms and tools for creating complex software in C++ to solve real world problems.

The database access library for C++ programmers that provides the illusion of embedding SQL in regular C++ code, staying entirely within the C++ standard.

The POCO C++ Libraries are powerful cross-platform C++ libraries for building network- and internet-based applications that run on desktop, server, mobile, IoT, and embedded systems. Whether building automation systems, industrial automation, IoT platforms, air traffic management systems, enterprise IT application and infrastructure management, security and network analytics, automotive infotainment and telematics, financial or healthcare, C++ developers have been trusting the POCO C++ Libraries for 15+ years and deployed it in millions of devices. Create software for connected embedded devices running Linux, Windows Embedded or QNX. Create cross-platform backends in C++ for iOS and Android applications and combine it with a native or HTML5-based user interface. Create software for IoT devices that talk to cloud backends over HTTP REST APIs. See macchina.io for an IoT platform built with POCO.

The CML (Configurable Math Library) is a free, open-source C++ vector, matrix, and quaternion math library designed for use in games, graphics, computational geometry, and related applications. Please note: the CML source has moved to GitHub: https://github.com/demianmnave/CML

Packaging of several commonly available open source libs with installers and selected design pattern implementations from journals such as Dr Dobb's, all using liberal LGPL and Boost licenses. Also intended to aid multi platform development.

Assorted projects. General-purpose libraries for Python, C++, Scala, bash, and others. Meta-programming tools. System utilities. UI components. Web APIs. Configuration files. Benchmarks. Programming competition entries. And much more.

A Boost.Application allows a developer run your application as a Windows service, as a Unix/Linux daemon, or as a usual interactive application (terminal) without the need to add extra code, the library abstract OS specific API and provide a ease common interface. To version beta4 (aspect based), check :https://github.com/retf/Boost.Application

This is a C++ logging library implementation which is accepted to Boost. It aims for extensibility and flexibility while moderately affecting user's application performance. Since being accepted, the library is developed and distributed as a part of Boost. Please, visit www.boost.org for more info.

Simple header-only library written in C++, for lexical analysis of files in PDF format

Implementation of cache conscious STL lists in Frias, L., Petit, J., and Roura, S. 2009. Lists revisited: Cache-conscious STL lists. J. Exp. Algorithmics 14 (Dec. 2009), 3.5-3.27. DOI= http://doi.acm.org/10.1145/1498698.1564505

A C++ library to manage compile-time intervals, provided as an extension of Boost.MPL.

Great code should mostly be self-documenting, but while using C++ in reality you can find yourself dealing with low-level stuff like iterators or hand-written loops that distract from the actual essence of your code. FunctionalPlus is a small header-only library supporting you in reducing code noise and in dealing with only one single level of abstraction at a time. By increasing brevity and maintainability of your code it can improve productivity (and fun!) in the long run. It pursues these goals by providing pure and easy-to-use functions that free you from implementing commonly used flows of control over and over again.

Implementation of paralell partitioning algorithms achieving an optimal number of comparisons. See L. Frias and J. Petit. Parallel partition revisited. http://dx.doi.org/10.1007/978-3-540-68552-4_11 for further reference.

A C++ library for creating textual Domain Specific Languages (DSLs).

Interval Container Library (ICL): An STL based generic library for computations on intervals, interval containers and cubes

Loge is a general purpose C++ library ( this sounds way better then saying it's a bunch of classes I found suited for publishing ). The Name is a homage to Andrei Alexandrescu's Loki library. It's all ANSI C++ and tr1, and therefore platform indep

The Mirror library provides both compile-time and run-time meta-data describing common C++ constructs like namespaces, types, classes, their base classes and member variables, constructors, etc. and provides generic interfaces for their introspection

Implementation of Multikey Quickselect and new Multikey Quicksort variants in Frias L, Roura, S. Multikey Quickselect. Technical report LSI-09-27-R, Universitat Politècnica de Catalunya, 2009. http://www.lsi.upc.edu/dept/techreps/techreps.html.

NOTE: Current source code as well as bugs/patches are on GitHub: https://github.com/pocoproject/poco/ C++ class libraries for network-centric, portable applications, integrated perfectly with the C++ Standard Library. Includes network protocols (Sockets, HTTP, FTP, SMTP, POP3, etc.), SQL database access and XML parsing. Licensed under Boost license.

Sequential and parallel implementation of string quicksorts(-select) . Articles: On the number of string lookups in BSTs (and related algorithms) with digital access/ Combining digital access and parallel partition for quicksort and quickselect.

This C++ library contains the 'PdfPageCount' class that performs the single task of finding the number of pages in a given PDF document. While the PdfPageCount class is very simple to use, the contained code is complex because the page count can be hidden in any number of places, quite often within compressed data.

PorTypes is a library of integer types. Currently, the library provides one unsigned integer type and one signed integer type. Both types have fixed width, which is specified at compile time via template parameters. The signed integer type uses 2's complement representation.

Spatial is a generic header-only C++ library providing multi-dimensional in-memory containers, iterators and functionals. Spatial is a general purpose library with good overall performance thanks to its self-balancing k-d tree containers. Spatial makes it easy to search for nearest neighbors, orthogonal ranges, or perform ordering of objects in any number of dimensions. Spatial's design borrows heavily from the STL, and strives to follow it's elegant interface; therefore Spatial's containers, iterators and functionals integrate well with the STL. Additionally, Spatial's self-balancing kd-tree based containers, capable of object insertion and removal in fractional amortized time, prevent worst-case computational time on most operations. The latest release brings bug fixes and wide array of performance improvement across several algorithms. Nearest neighbor search, in particular, has been improved significantly.

C++ toolkit library for Direct3D 11. Provides an application framework, similar to other toolkit libraries such as GLUT, and utility classes and functions for making various Direct3D 11 tasks easier and more robust.
