I'm clueless.... any ideas?
Have you added the CoreLocation library to your project? Looks like your having problems linking, which usually means you don't have all the libraries your project needs.

this is the error I am getting when I try to run the file ... I have imported those classes from another project into this one which was non arc based and converted to ARC. I got this error after successfully removing all the references to autorelease and retains from it.
Did you try Product->Clean?
Or restarting XCode?
Did you make sure you've included everything in the Targets->Build Phases->Compile Sources? Xcode does this for you, but sometimes it misses things.
Can any one tell me the meaning of this error ,
this is the details of the error log :

It's a linker error, ensure that KalViewController is added to the current target, choose Get Info on it and go to the targets tab, ensure that the box is ticked.
In the Kal project's settings, make sure that it is compiled for the i386 architecture.
I'm having some hard time with the iOS GameCenter
I'm following some tutorials on youtube
but as soon as I finish the code I get this error:

It looks like you haven't added the GameKit framework to your project.
If your using Xcode 3.2.x:
Right click the Frameworks group/folder in the file tree (on the left of the xcode window)
Press Add, and then select Existing Frameworks...
Scroll to GameKit.framework and double click it
If your using Xcode 4:
In the file tree, click on the project (the item at the top)
Select your target
Go to the Build Phases tab on the main panel
Expand the Link Binary with Libraries
Press the + button
Scroll to the GameKit.framework and double click it.
Did you add the GameKit.framework to your project?

Looks like you need to include the MediaFramework in your project.
I had the same issue while all frameworks and compiling sources were added. What fixed my issue was to delete ~/ProjectFolder/MediaPlayer.framework/MediaPlayer.exec file, and then build and run, and it worked!
On a fresh install of Xcode 3.1.2, I'm trying to use the iPhone MoviePlayer as shown in the sample code at http://developer.apple.com/iphone/library/codinghowtos/AudioAndVideo/index.html#INITIATE_VIDEO_PLAYBACK_IN_MY_CODE
However, Xcode reports the following linker errors when I try to build-n-go:

that is right. Another way to do it is by adding the MediaPlayer to the Project Target by selecting TARGETS->Build Phases->Link Binary with Libraries (here add MediaPlayer)
Yes, if your code calls into a framework, you have to add that framework to your target and link against it.
Make sure the framework is "Relative to Current SDK" (select the framework > Get Info > General tab) so that when you build for the device, it links against the device's version, not the simulator's.
Found the problem. I haven't read all the docs, but there are a lot of them...
Anyway, I fixed this by dragging the directory
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator2.2.1.sdk/System/Library/Frameworks/MediaPlayer.framework/
into the Frameworks folder in XCode and clicking OK on the import dialog.
