I have recently picked up a flojack device and I am trying to link in the library to use the device and I am getting the following error on link.

Undefined symbols for architecture arm64:
“_OBJC_CLASS_$_ACRAesTrackData”, referenced from:
objc-class-ref in ViewController.o
“_OBJC_CLASS_$_ACRDukptTrackData”, referenced from:
objc-class-ref in ViewController.o
“_OBJC_CLASS_$_ACRAudioJackReader”, referenced from:
objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have followed the instructions on the github site, but it seems like there is something missing…

Any help would be much appreciated.

xcode version is 7.1 and I am targeting iOS 9

Also just an update…

Adding the .a file to the link gives the following error…

ld: ‘/Users/sh4d0wz/Development/CTS/ios/CTS/AudioJack/libAudioJack.a(ACRDukptReceiver.o)’ does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Hell Bill,

Please disable Bitcode.

Go to the targer Build Settings, find the “Enable Bitcode” field and set it to “NO”.
