Error debugging app on Iphone 3G with XCode 4.2

Question

I have an app working on Iphone 3GS, Ipad and Iphone simulator. Now I'm trying to test and debug on an Iphone 3G and I can't

Fist, XCode asked me to download some library. I did it!

Then, I had problem with the Architecture and searching on internet i found the solution. Setting the Architecture on armv6 and armv7

Now, when I start the app for debugging it show me this log:

You are trying to use UIPopoverController in an iPhone application. UIPopoverController is not available in iPhone it is for iPad only. You can put a conditional to avoid the use of UIPopoverController at runtime in case of iPhone device.

I searched for UIPopoverController on my app and is used by ZBar's class ZBarCameraSimulator as a type for a property. Isn't my code, is from ZBar Library I think. I can't change it But, is strange, becouse on an Iphone 4.0 it works correctly – Mark Comix Dec 13 '11 at 15:28

The problem is not that he's calling UIPopoverController but that iOS can't find the UIPopoverController in its SDK when loading the app on the 3G phone. The linker reference to it should be a [weak link](http://stackoverflow.com/a/3027213/154803) so that it is optional, this allows the app to load without resolving the reference. – progrmr Dec 13 '11 at 15:31
I changed the library to Optional (is the same as weak?) and also crash and show me another Log with diferent problems. I don't see that as a solution – Mark Comix Dec 13 '11 at 15:42
