Answer 1

Looks like you've added to the project twice adWhirl / adMod SDK. Check carefully all the branches of your project in the left pane.

Also, do clean-up project with the help of the following: the top menu -> Product -> Clean. After that, the same steps, but before this, press and hold Alt.

I got it, i dragged entine adMob folder to my project folder in xcode. Butg in that adMob folder another sample example xcode project exists which caused that 'main' conflicts. I removed sample appllication from adMob and its recompiled and worked fine. Infog, thats a lot for your reply.
