i am facing the same issue and i think it is because the library does not supports simulator SDK. it should compile on device

I don't know much about POCO, but looking at your call to clang++ I can safely say that you're not linking any POCO libraries to your application.

Be sure to specify correct values for '-L' and '-l' options (there must be a way to do this in XCode) and everything should hopefully work.
