Now, we need to switch to the downloaded folder and unpack the file by − This can be done by downloading the package from. In order to get full features of Objective-C, download and install GNUStep. Libxml2 libxml2-devel libX11-devel libXt-devel libjpeg libjpeg-devel

$ yum install make libpng libpng-devel libtiff libtiff-devel libobjc The next step is to set up package dependencies using following command − The initial step is install gcc along with gcc Objective-C package. GCC compiler is available for free on various platforms and the procedure to set up on various platforms is explained below. I assume you have basic knowledge about a programming language compiler. This GCC compiler will be used to compile your source code into final executable program. It needs to be 'compiled' to turn into machine language, so that your CPU can actually execute the program as per instructions given. The source code written in source file is the human readable source for your program. m'.īefore starting your programming, make sure you have one text editor in place and you have enough experience to write a computer program, save it in a file, compile it and finally execute it. The source files for Objective-C programs are typically named with the extension '. The files you create with your editor are called source files and contain program source code. For example, Notepad will be used on Windows, and vim or vi can be used on windows as well as Linux or UNIX. Name and version of text editor can vary on different operating systems. Examples of few editors include Windows Notepad, OS Edit command, Brief, Epsilon, EMACS, and vim or vi. If you are still willing to set up your own environment for Objective-C programming language, then you need to install Text Editor and The GCC Compiler on your computer.
