DJGPP

DJGPP provides a set of development tools and utilities intended for Intel systems higher than 80386 that run on MS-DOS-compatible operating systems. Built using the C/C++ programming languages, DJGPP is especially created for 32-bit architectures and bundles components that can be used to create 386+ MS-DOS applications.
The package includes libraries, runtimes and development kits, working alongside the integrated DOS compiler to help you generate applications. Furthermore, it bundles a set of programs dedicated to testing the main C library.
DJGPP assists developers in building C or C++ programs. Once you have all the required packages and components, you must configure the the DJGPP environment variable, an operation that requires different actions, depending on the operating system your computer is running on.
The console-based compiler can be launched from the DOS command line window, enabling you to compile a C or C++ source file to an object file and then generate an executable program that can be deployed on any DOS-based system.
DJGPP can be integrated and invoked from within any IDE that supports DOS programming, such as Emacs or Rhide. Please note that this package does not comprise its own IDE.
DJGPP features a collection of GNU development tools that facilitate the development of DOS-based applications. The programs generated with its help require a 386 or newer computer to run and thanks to the open-source license of DJGPP, they can be used in both personal and commercial environments.
