Revision as of 16:44, 28 December 2013
Objective C 2.0 on a fresh install of Ubuntu 12.10 Server
- Uses llvm/clang source to ensure all the latest features are available.
- Also works on Ubuntu 13.10 Desktop.
- Includes GUI at the end
- When compiling, it is generally good to tell clang both the family and version of the runtime: -fobjc-runtime=gnustep-1.7
(The current version number can be had by looking at the latest ANNOUNCE filename in http://svn.gna.org/svn/gnustep/libs/libobjc2/trunk/ (e.g., ANNOUNCE.1.7))
