libGoogleAnalytics.a linking problems with iPhone iOS4 Simulator

Question

I recently upgraded to the iOS4 SDK and my app no longer compiles for the simulator, but does compile for the device.

This is due to the 3rd party library libGoogleAnalytics.a. The solution seems to be for google to release a new static library complied with the new SDK, unfortunately there is no word of any release date, and due to the new SDK licensing, they may never release a new library.

I am getting the following compile errors:

One suggestion on the google forum is to create a dummy implementation of the GANTracker class for use in the simulator. ie to create a file GANTracker_stub.m:

#import "GANTracker.h"

#if TARGET_IPHONE_SIMULATOR

@implementation GANTracker

+ (GANTracker *)sharedTracker
{
    return [[[GANTracker alloc] init] autorelease];
}

- (void)startTrackerWithAccountID:(NSString *)accountID
               dispatchPeriod:(NSInteger)dispatchPeriod
                     delegate:(id<GANTrackerDelegate>)delegate
{
}

- (void)stopTracker
{  
}

- (BOOL)trackPageview:(NSString *)pageURL
        withError:(NSError **)error
{
    return YES;
}

- (BOOL)trackEvent:(NSString *)category
        action:(NSString *)action
         label:(NSString *)label
         value:(NSInteger)value
     withError:(NSError **)error
{
    return YES;
}

- (BOOL)dispatch
{
    return YES;
}

@end
#endif

This however is not working for me, is there something I'm missing?

Solution found via the Google Analytics forum:

Use:

lipo libGoogleAnalytics.a -remove i386 -output libGoogleAnalytics2.a

Then delete libGoogleAnalytics.a from your project and add libGoogleAnalytics2.a

This only works in conjunction with the dummy implementation of GANTracker as shown above.
