This tutorial will explain how to set up environment for successful building Objective-C applications on Ubuntu for total beginners (without Apple machine) :).
It’s based on this step by step wizard: Getting started with Objective C on Ubuntu.
We can’t use default Cocoa implementation from iOS, instead we have another implementation suitable for Linux: GNUstep.
- Install headers for gcc:
sudo apt-get -y install build-essential
- Install GNUStep:
sudo apt-get install gobjc gnustep gnustep-make gnustep-common
- Add next line to .bashrc
#GNUSTEP Environment vars
And you are good to go. How to create make file and Hello World follow this link: Getting started with Objective C on Ubuntu.
