GNU/Liberty Basic Compiler Collection (GLBCC) is a suite of tools that allow Liberty Basic source code to be compiled directly to executable programs. It leverages greatly off of the GNU Compiler Collection, which allows it to run both on Windows and Linux, while also having the ability to generate both Linux and Windows executables on Linux via the Mingw cross compiler. The suite also includes a frontend program that has both a GUI and CLI to provide a simple environment to compile Liberty Basic code.
wxBase contains most of the non-GUI classes from the wxWindows cross-platform C++ framework. There are 2 categories: generally useful portable code (date/time handling, command line parsing, regular expression support) and wrappers for the OS objects (files, directories, sockets, threads, etc.) allowing you to write portable programs easily.
The OpenAI site is centered around an Open Source project and community involving artificial intelligence. The project itself is the creation of a set of tools that are considered to be models of human intelligence or biomimicry. These tools are intended to be integrated into applications or used stand alone for research.
