As you said, you're using the Google Maps SDK for iOS. Yet, it looks like you are compiling for OS X, as the symbols are undefined for i386, an Intel processor. (Unless you are trying to compile for the simulator)
The SDK may not be compiled for the simulator. You can check by running the SDK binary through the "file" command. If it has support for ARM processors, but not i386, it doesn't have support for the simulator. You'll have to change your build flags to only compile for armv7/armv7s processors.
