Running a custom-compiled executable returns "No such file or directory"

I have an executable but when I run it I get *"No such file or directory"* $ chmod a+x bin $ file bin bin: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld64.so.1, not stripped $ ./bin bash: ./bin: No such file or directory Notice that this executable is in fact ELF 64-bit, as is the operating system.
