Having trouble using SDL framework on XCode

I am having trouble using the SDL framework in my xcode project, my main (all there is in the project at the moment) currently looks like this:

#include <SDL/SDL.h>
#include <iostream>

int main(int argc, const char * argv[])
{
// insert code here...
std::cout << "Hello, World!\n";
return 0;
}

And the error I am receiving when building is:

Undefined symbols for architecture x86_64: "_main", referenced from: start in crt1.10.6.o (maybe you meant: __Z8SDL_mainiPPKc) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

It does not give me an error about the framework not being found. and I have looked around Stackoverflow for this problem and I did find one person who had their framework in the wrong place on their OS. But I have tried all places (/library/frameworks && /~username~/library/frameworks && /system/library/frameworks) and still no luck.

Additional info: I did however notice after some searching on the internet that the official website http://www.libsdl.org/download-1.2.php Does not have a OSX version of the Development library. While many tutorials on how to use SDL on OSX say these are required.

Also I am adding my library via Xcode itself ,not through drag'ndrop. Xcode seems to reckognize it.

Would be much appreciated if anyone could help, going crazy over this error.

UPDATE:

error

Still no luck, I have followed every step provided by solutions here below. perhaps this screenshot is of any help.

The main() function is corrected, but didn't help. I tried changing the path to the header files, im lost on this one. Does anyone perhaps have any alternatives to building this in xcode?

UPDATE2:

The suggestion worked, however now it is giving me this warning, which won't let me run the application.

enter image description here

Fixed! I removed the path in the build settings. Strange how I still don't know what went wrong, either way. thanks a lot for the help! made my day!

I see three possible problems. The first problem is how you're including SDL.h in your code. You should include SDL.h with the following code:

#include "SDL.h"

The second possible problem is you haven't added the files SDLMain.h and SDLMain.m to your project. Those files are necessary to compile SDL code on Mac OS X. The files are in the devel-lite folder on the SDL disk image.

The third possible problem is that your project doesn't link to the Cocoa framework. The Mac version of SDL uses Cocoa so you need the Cocoa framework in your project.

The following article walks you through the setup of an Xcode 4 project for SDL:

Using SDL with Xcode 4

UPDATE

I noticed a possible problem in how you defined the main() function. You have a space between char and * and another space between * and argv, which could be causing the error. The main() function in my SDL code is defined in the following way:

int main(int argc, char *argv[])
