Check if your project links libCordova.a (in my case Xcode forgot about the reference, when moving CordovaLib.xcodeproj to another location).

select your project in the Project Navigator
go to the Summary tab
drag CordovaLib.xcodeproj > Products > libCordova.a to Linked Frameworks and Libraries

Clean & build.

Please check your ViewController.m file and goto to 1. Build phase in xcode 2. Select Compile Sources 3. Press + button to add .m/.mm file

I think it will run successfully now

Soory. Now i got the Above same error. Then what is that .m/.mm file. Sorry. I can't get that message. Sorry. – Spenser 27/9, 2012 at 12:30

.m/.mm file means ViewController.m /ViewController.mm file or any other viewController .m or .mm file(Source code).Please add all .m or .mm file to Build Phase->Compile Sources.Then clean your project and build again. – Beatrix 28/9, 2012 at 4:48

Remove armv7s from your build settings, for both your project and the referenced subproject Cordova. Set your target to 4.3.

I had a similar issue. Somehow my the NSManagedObject Sub-classes of my Core Data entities were in the Compile Sources table twice. The compiler would choke when it hit the first of these duplicates.

I just went into the Compile Sources table and deleted the second occurrence of each .m listing.
