GNUstep under Ubuntu Linux

Objective-C under Ubuntu Linux

Compiling Everything from Scratch

The following repo contains scripts that compile and install everything needed for GNUstep Objective-C 2.0. The script uses clang and libobjc2 for all the awesome new features like ARC, blocks/Grand Central Dispatch, etc.

For example, to build GNUstep under Ubuntu 19.04, do:

git clone https://github.com/plaurent/gnustep-build
cd ubuntu-19.04-clang-8.0-runtime-2.0
./GNUstep-buildon-ubuntu1904.sh

Reference manuals for GNUStep, including available APIs, etc, are available at http://www.gnustep.org/developers/documentation.html

General Note: When compiling your own code, it is generally good to tell clang both the family and version of the runtime: -fobjc-runtime=gnustep-2.0 (The current version number can be had by looking at the latest ANNOUNCE filename in https://github.com/gnustep/libobjc2 (e.g., ANNOUNCE.1.8.1))
