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) << '\n'; 

/Applications/myApp

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

Answer 1

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!!!!
