Re: Error adding the library to a project

[Greg Robbins]

It looks like GTLObject.m (or an umbrella source file that includes it, like GTLCommon_Sources.m) isn't being compiled into your project or linked into your application target.

This problem seems when your header search path is not correct. so please go with the command line for the path where you download your api . Type the command pwd , copy the link upto source and add in the user header search path.
