Undefined symbols for architecture i386: "_SCNetworkReachabilitySetCallback" - sefiroths - Aug 18, 2011 11:31 AM

i use xcode4, on a openglES project
i have added code for in-app purchase from the tutorial:
http://www.raywenderlich.com/2797/introduction-to-in-app-purchases

i have added SystemConfiguration.framework but this errors occurs:

if i delete framework reference the error is the same.
adding again nothing happens...
in -Xlinker 2 -framework Foundation -framework UIKit [...] sould i see "-framework SystemConfiguration" right?
why is not there?
do anyone has ideas?

pulling up the framework from the project->build phases->link binary with library making it the first framework i have this erros:

found it!
i have copied the SystemConfiguration.framework into my project folder (checking the box when i added from xcode).
deleting that folder in my project now compiles well
