If you are on 32-bit hardware, you do not have 64 bit types. Try this: (cffi:foreign-type-size :long) if it says 4, you're out of luck. If it says 8, you should be all set. That result is determined by the hardware, the OS, and the Lisp implementation, not by GSLL/grid.

There is no class named GRID::VECTOR-UNSIGNED-BYTE-64. [Condition of type SIMPLE-ERROR]
Looking at the gsd code I found the following in foreign-arrays & friends.
*array-element-types* does not contain 64-byte definitions:
(SINGLE-FLOAT DOUBLE-FLOAT (COMPLEX SINGLE-FLOAT) (COMPLEX DOUBLE-FLOAT) (SIGNED-BYTE 8) (UNSIGNED-BYTE 8) (SIGNED-BYTE 16) (UNSIGNED-BYTE 16) (SIGNED-BYTE 32) (UNSIGNED-BYTE 32))
and neither does *cstd-cl-type-mapping*
This may be because *cstd-cl-type-mapping* does not have an entry that would correspond to a 64 byte integer - and I don't have a clue as to what such an entry would be.
