Romcnv Compiled For Mac

I am new to Qt and develop on a Mac - managed to get some of the examples working via XCode but the Qt Creator throws the message below

:-1: error: Qt Creator needs a compiler set up to build. Configure a compiler in the kit options.

when I try to compile.

In the preferences pane there seem to be various autodetect compilers flagged though if I select a sensible one of these it doesn't seem to make any difference.

Not sure if this means there was something wrong with the Qt install itself - I am using OSX 10.7.5 and Xcode 4.5.2..

I have Mac OS X Mountain Lion. I need to compile a few apps and Perl modules. 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
Sample outputs:

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:

To compile, enter:
$ make a
Run it as follows:
$ ./a
Sample outputs:

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:

$ man gcc
$ man make
