NASM compiles just fine, but when i use YASM I'm getting the following error:
hello.asm:12: error: macho: sorry, cannot apply 32 bit absolute relocations in 64 bit mode, consider "[_symbol wrt rip]" for mem access, "qword" and "dq _foo" for pointers.

Anyone know what's going on? And if you could explain why NASM works, but YASM doesn't that would be a bonus.
