Description:
Free Pascal - base units
The Free Pascal Compiler is an Object Pascal compiler supporting both Delphi and Turbo Pascal 7.0 dialects, as well as Mac Pascal dialects. It provides a completely portable RunTime Library (RTL) available on many platforms and compatible with Turbo Pascal, along with a platform-independent class-based Free Component Library (FCL) adding many Delphi extensions and interfacing with many popular open source libraries. . This package contains Free Pascal units for common libraries (some of which are also required by the Free Component Library): NCurses, X11 (Xlib, Xutil), and ZLib.
