GNUstep Objective-C Runtime 1.2 =============================== This is the 1.2 release of the GNUstep Objective-C runtime (a.k.a. libobjc2). This runtime was designed to support the features of Objective-C 2 for use with GNUstep and other Objective-C programs. This release contains several bug fixes, and is tested with the current GNUstep trunk, so will be compatible with the upcoming GNUstep release. You may obtain the code for this release from subversion at the following subversion branch: svn://svn.gna.org/svn/gnustep/libs/libobjc2/1.2 Alternatively, a tarball is available from: http://download.gna.org/gnustep/libobjc2-1.2.tar.bz2 The runtime library is responsible for implementing the core features of the object model, as well as exposing introspection features to the user. The GNUstep runtime implements Apple's Objective-C Runtime APIs, and a small number of GCC APIs for legacy compatibility. This library is based on the Étoilé Objective-C Runtime, an earlier research prototype, and includes support for non-fragile instance variables, type-dependent dispatch, and object planes. It is fully compatible with the FSF's GCC Objective-C ABI and also implements a new ABI that is supported by Clang and is required for some of the newer features. Although the runtime has been tested by several people, and is being used extensively by the Étoilé project, it is entirely new (MIT licensed) code and may still contain bugs. If you come across any problems, please report them to the GNUstep Developer mailing list .
