The basics of Objective-C are supported by the GNU compiler collection. In order to utilize the full power of Objective-C together with the Cocoa /openStep environments on Linux, and to work with many of the examples covered in this book, it is necessary to install gcc, the gcc Objective-C support package and the GNUstep environment.

Assuming you see output similar to the above example, Objective-C and GNUstep are successfully installed on your Linux system and you are ready to continue with the remainder of this book.
