I have Mac OS X Mountain Lion. I need to compile a few apps and Perl modules. Then I already installed Xcode from app store but I’m unable to find gcc compiler or make command. How do I install gcc on Mac OS X 10.8.x?
Xcode includes command line development tools such as gcc and friends.
Step #1: Install Xcode on a Apple Mac OS X
First, make sure Xcode is installed. If it is not installed on OS X, visit app store and install Xcode.

Step #2: Install gcc/LLVM compiler on OS X
Once installed, open Xcode and visit:
Xcode menu > Preferences > Downloads > choose Command line tools > Click Install button:

Xcode will download package and install copies of the core command line tools and system headers into system folders, including the LLVM compiler, linker, and build tools.
Step #3: Verification
Open a terminal app and type the following commands:
$ gcc –version
$ whereis gcc
$ whereis make

Testing sample “Hello world” C program
Create a text file called a.c as follows using a text editor such as vi or cat command:
/* a.c – demo for os x */
printf( Hello world\n );
To compile, enter:
$ make a
Run it as follows:

And, there you have it, the gcc version 4.2.1 installed and working correctly on the latest version of Mac OS X 10.8.4. In Apple’s version of GCC, both cc and gcc are actually symbolic links to the llvm-gcc compiler. Similarly, c++ and g++ are links to llvm-g++. For more information and examples see the following man pages:
