GNUstep Getting Started

Objective-C popularity aggressively increased based on TIOBE Index (for October 2009)

The reason is simple -- iPhone and all related stuff. We should be ready to develop Objective-C based application in future. The worst thing I don't have a Mac, so I don't have development environment.
I need to get basic Objective-C knowledge, and here several solutions:
  • buy Mac
  • install Hackintosh on PC
  • try GNU compiler and play with Objective-C
The better choice is the last one (for me). As I'm a Windows XP user and I don't have a time to set up Linux, I'm going to use some Windows GNU GCC port: Cygwin or MinGW.
There are two cross-platform projects which implements Objective-C Cocoa/OpenStep APIs:
  • The Cocotron -- this project uses Mac machine for build (I didn't dig into this), but built application can be run on Windows.
  •  GNUstep -- this project supports many platforms (Windows included).
My choice is

Here is the useful links for quick start:
How to build your first GNUstep application in Windows?
In general it's simple, but if you have some troubles with it here is the links:
  1. Installing and using GNUstep and Objective-C on Windows
  2. Writing GNUstep Makefiles (I highly recommend it)
  3. Compile Objective-C Programs Using gcc
The next post will be about tuning the development environment for GNUstep .
