I tried to
make gpu=1 ccap=53 all
compile on nVidia jetson nano, but since it is ARM architecture, there is no x86 -m64 -mssse3, and i removed -m64 -mssse3 the compile has error.
Has anyone tried to compile on ARM?
GPU: 128-core NVIDIA Maxwell™ architecture-based GPU
CPU: Quad-core ARM® A57
Memory: 4 GB 64-bit LPDDR4; 25.6 gigabytes/second

Kangaroo uses some Intel assembly instructions baked inside the integer classes so you'd have to find their ARM equivalents and put a macro in them like this:
Code:
void Int::add(Int& a, In& b, Int& c) {
#ifdef ARM_CPU
/* Arm instructions */
#else
/* Intel instructions */
}
#ifdef ARM_CPU
/* Arm instructions */
#else
/* Intel instructions */
}
And then compile with ARM version of GCC or cross-compile using Clang.
yes, I see kangaroo use Intel __builtin_ia32_addcarryx_u64 _addcarry_u64 etc.
I try to search the way to replace those functions.
Thanks.
