Are you using a library? Because the linker is saying it's not finding x86_64 bit code for some routines. Maybe the library needs to be re-compiled for your architecture choice.

You shouldn't post an image when you're trying to post what is text information

Either way, it looks like you are linking to a 32-bit library instead of 64-bit.
