gnustep The GNUstep Database Library 2 (GDL2) is a set of libraries to map Objective-C objects to rows of relational database management systems (RDBMS). It aims to be compatible with Enterprise Objects Framework (EOF) as released with WebObjects 4.5 from Apple Inc. It requires the GNUstep Make Package 1.9.1 and the Base Library 1.9.1. Alternatively it is meant to work with other OpenStep-like implementations like Cocoa together with the GNUstep BaseAdditions Library 1.9.1. For UI applications which may want to use adaptor specific login panels, you should also install the GNUstep GUI Library 0.9.2 and the GNUstep Backend Library 0.9.2.
