xcode 5.1 - Undefined symbols for architecture x86_64 (zbar)

Question

I have updated my x code version from 5.0 to 5.1
I have used ZBarSDK in my project for scan bar code. In simulator \'iPhone Retina (3.5-inch)\' and \'iPhone Retina(4-inc

Answer 1

This implies the library is not supported/built for the new archtitecture.

For zBar this answer has link to tutorial where you can download the source and just update the lib to new architecture.

Generally for a third party service. they will release new lib with the architecture added so make sure to check out their site for updated SDK.
