[SOLVED] Undefined symbols for architecture x86_64: "

Undefined symbols for architecture x86_64: "_CFBundleCopyResourceURL",

Trying to access the file path to the resources folder in a Mac .app bundle using Qt. Here's my code:

CFURLRef appUrlRef;


appUrlRef = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("AFE-MP-512"),NULL,NULL);
CFStringRef filePathRef = CFURLCopyPath(appUrlRef);



qDebug() << filePathRef;

// Release references
CFRelease(filePathRef);
CFRelease(appUrlRef);

The only thing I have is a pushbutton on the form to run the code. Getting the following error when trying to compile:

Undefined symbols for architecture x86_64:

I have the following includes in mainwaindow.h

#include <QtCore>
#include <CoreFoundation/CFURL.h>
#include <CoreFoundation/CFBundle.h>

Any ideas what could be going wrong? Thanks

Solution

You need to link with the CoreFoundation framework. You can add the following to your qmake project:

LIBS += "-framework CoreFoundation"
