XCode linker error : library not found for -lAdMobDevice

Question

I am trying to build lite version of my iPhone application using AdMob. I followed the guidelines here http://www.iphonedevsdk.com/forum/iphone-sdk-development/11358-creating-lite-version-app.html and created two different targets. In the lite version I added a macro called LITEVERSION which I am checking using #ifdef and doing the appropriate things.

But when I build the lite version of the app, I get a linker error

ld: library not found for -lAdMobDevice collect2: ld returned 1 exit status

However I am able to build the full version without any issues and also noticed that build is working fine (for the fullversion) even if I remove the #ifdef macros. This suggests that the libAdMobSimulator.a library is linking properly for the full version however it fails on the lite version.

Any pointers would be greatly appreciated!

Answer 1

When I had this problem, the cause was that I'd added the library into Xcode by dragging it in like a regular source file.

The fix was to remove it, and then add it properly using the "Add->Existing Frameworks..." dialogue.

Answer 2

I got similar error as I was using CocoaPods libraries

library not found for -lPods-MyApp

I got the error because I opened xcode project instead of workspace .

Answer 3

我正在使用CocoaPods ，并运行pod install ，并修复它。

Answer 4

I figured out what he problem was. I just removed all frameworks and libraries and added them back in for both the targets and it worked!

I cause this because of a libray libMobClickLibrary.a which is used in youmeng sdk missed. I fix the issued after copy libMobClickLibrary.a to the project floder.

I had the same problem with Google Analytics library. My problem was that I forgot to add the path to the Library Search Paths in my target's build settings. (Target -> Build Settings -> Library Search Paths)
