Undefined symbols for architecture armv7 while using Google-Maps-iOS-SDK (1.8.1)

Question

I am trying to add Google-Maps-iOS-SDK (1.8.1) using cocoapods (0.33.1).

Deployment target version: iOS 7.0

I have added this pod: pod 'Google-Maps-iOS-SDK', '~> 1.8' Downloaded and installed sdk properly.

I started adding header file and sample map view loading code from here.

I have properly added API keys. In one view controller's - (void)viewDidLoad,
I have added following code:

 // Create a GMSCameraPosition that tells the map to display the
// coordinate -33.86,151.20 at zoom level 6.
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                        longitude:151.20
                                                             zoom:6];
GMSMapView *mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
self.view = mapView_;

// Creates a marker in the center of the map.
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
marker.title = @"Sydney";
marker.snippet = @"Australia";
marker.map = mapView_; 

I got this error on build for iPhone (not in simulator)

Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_GMSMarker", referenced from: objc-class-ref in DealDetailsViewController.o "_OBJC_CLASS_$_GMSMapView", referenced from: objc-class-ref in DealDetailsViewController.o "_OBJC_CLASS_$_GMSCameraPosition", referenced from: objc-class-ref in DealDetailsViewController.o "_OBJC_CLASS_$_GMSServices", referenced from: objc-class-ref in AppDelegate.o ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I also tried using google map iOS sdk manual installation (without cocoapods). I have also added linker flag: -ObjC. It builds fine but crash on runtime showing selector not found error like this:

an NSException is thrown with the description - -[GMSMapView animateToCameraPosition:]: unrecognized selector sent to instance.

I just need to use google map iOS SDK either using cocoapod or from manual installation.

Am I missing anything here?

Edit

If there is anything related with Pods.xcconfig then here is the content of that file:

It's looks like the linker cannot find a sdk lib. Headers are present, but sdk objects-file not linked to a project.

Checking this:

BuildSettings->Linking->Other Linker Flags must have a value $(inherited)
