I have a project that built and ran yesterday, but today it doesn't link. I didn't change anything. I don't know what would cause this. I don't see main.o and _main that it is referring to. Any ideas? I tried a clean and build. I looked at a couple of things on this site but don't see anything that's clueing me in.

Thanks.
Your classes are missing from Build target. I don't know about your project structure and files but it looks like GADBannerView and GADRequest classes are missing.
Remove these files from your project. add them again and remember to check "ADD TO TARGET" checkbox.
Add the libGoogleAdMobAds.a to the Linked Frameworks and Libraries.
this error shows that u haven't added GADBannerView, and GADRequest classes.
please check by following this steps:
in XCode select your Project in the Target Section then switch to BuildPhases->CompileSources
here check for GADBannerView.m and GADRequest.m files.
XCode->Your Project in Target section->BuildPhases->CompileSources
hope this will help you.

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.
I'm having some hard time with the iOS GameCenter

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?
I am trying to add PinkelStar Sharing function to my own app, I follow every step the instruction says, but it did not turn out to be the way it should be. I am a newer to iPhone development, question might be stupid.

Thank you for your help!!
Tony
It looks like you are not linking all the needed Frameworks into your project. Please take a look at the Readme.mdown that lists all of the frameworks and include them into your project. That will resolve these issues.
Required frameworks may not be added to the project correctly or the path given for the framework in Framework search path may be incorrect.Verify.If you are not adding any private framework then leave Framework search path blank and then try.
How can i fix it

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!
