Gecode is an open source C++ toolkit for developing constraint-based systems and applications. Gecode provides a constraint solver with state-of-the-art performance while being modular and extensible.
You can find lots of information on Gecode's webpages, including how to download, compile, install, and use it.
In particular, Gecode comes with extensive tutorial and reference documentation. The tutorial Modeling and Programming with Gecode explains how to model and solve problems with Gecode, and the reference documentation describes the complete API.
Gecode 6.5.0 is distributed as source code. Source archives can be downloaded from GitHub or Gecode's webpages.
Gecode builds with CMake or Autoconf. The
CMake build and package reference describes the build
options, installation, and how downstream projects use the installed package
with find_package(Gecode).
