Relative Paths Not Working in Xcode C++

Question

There are numerous post over the net that detail how relative paths don't work in Xcode. I do have an Xcode template that I downloaded where the relative paths DO work, however I have not been able to figure out why nor replicate it in other projects.

Firstly, I am using C++ in Xcode 3.1. I am not using Objective-C, nor any Cocoa/Carbon frameworks, just pure C++.

Here is the code that works in my other Xcode template:

sound->LoadMusic( (std::string) "Resources/Audio/Pop.wav" );

This relative path works for me also in Windows. Running the following command gives me an absolute path to the application's full path:

std::cout << "Current directory is: " << getcwd( buffer, 1000) << "
";

/Applications/myApp

How can we get relative paths to work in an Xcode .app bundle?

Took me about 5 hours of Google and trying different things to FINALLY find the answer!

#ifdef __APPLE__
#include "CoreFoundation/CoreFoundation.h"
#endif

// ----------------------------------------------------------------------------
// This makes relative paths work in C++ in Xcode by changing directory to the Resources folder inside the .app bundle
#ifdef __APPLE__    
    CFBundleRef mainBundle = CFBundleGetMainBundle();
    CFURLRef resourcesURL = CFBundleCopyResourcesDirectoryURL(mainBundle);
    char path[PATH_MAX];
    if (!CFURLGetFileSystemRepresentation(resourcesURL, TRUE, (UInt8 *)path, PATH_MAX))
    {
        // error!
    }
    CFRelease(resourcesURL);

    chdir(path);
    std::cout << "Current Path: " << path << std::endl;
#endif
// ----------------------------------------------------------------------------

I've thrown some extra include guards because this makes it compile Apple only (I develop cross platform) and makes the code nicer.

I thank the other 2 guys for your answers, your help ultimately got me on the right track to find this answer so i've voted you both up. Thanks guys!!!!
