Hi, I tried to load cffi that comes with Quicklisp on SBCL 1.3.2 on a Raspberry PI 2.
I had to comment out FFI_UNIX64
(cenum abi ((:default-abi "FFI_DEFAULT_ABI")) ((:sysv "FFI_SYSV")) #+nil ((:unix64 "FFI_UNIX64")) )
in the file quicklisp/dists/quicklisp/software/cffi_0.16.1/libffi/libffi-unix.lisp to make it load.
