Using the attached patch, x265-arm-asm-primitives.patch, from:https://git.pantherx.org/mirror/guix/blob/985d542e028517b2888fa61831233a2b60dc7d48/gnu/packages/patches/x265-arm-asm-primitives.patch ..fixes the problem. This appears to be for x265_2.8, but it has not been applied to x265_3.3? Regards John
