Using Apple's Reachability code in iOS5 I get a bunch of compilation errors as shown below. Any ideas on what is happening here? I'm using ARC so I have edited the standard code slightly to remove autorelease/retain and the NSAutoReleasePool.

Undefined symbols for architecture armv7:

"_SCNetworkReachabilityCreateWithAddress", referenced from: +[Reachability reachabilityWithAddress:] in Reachability.o

"_SCNetworkReachabilityCreateWithName", referenced from: +[Reachability reachabilityWithHostName:] in Reachability.o

"_SCNetworkReachabilityUnscheduleFromRunLoop", referenced from: -[Reachability stopNotifier] in Reachability.o

"_SCNetworkReachabilityScheduleWithRunLoop", referenced from: -[Reachability startNotifier] in Reachability.o

"_SCNetworkReachabilitySetCallback", referenced from: -[Reachability startNotifier] in Reachability.o

"_SCNetworkReachabilityGetFlags", referenced from: -[Reachability connectionRequired] in Reachability.o -[Reachability currentReachabilityStatus] in Reachability.o

ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Does anyone have workable Reachability code for ARC under iOS5?

I wrote a clean 'drop in' version of reachability for ARC and iOS5 - you can get it here: https://github.com/tonymillion/Reachability
