"Unsupported integer type" for unsigned long long (uint64_t) value type of cuco::static_map

[Gibyeng]

When I create a static_map with unsigned long long type, there is a error: fast_int.cuh(36): error: static assertion failed with "Unsupported integer type".
It seems that the reason is that current INT128 is not supported. how to enable INT128 setting?

My nvcc version is 13.8 which should support int128 and I test the following code in my machine

#ifdef __CUDACC__
  printf("__CUDACC__ defined\n");
#endif

#ifdef __SIZEOF_INT128__
  printf("__SIZEOF_INT128__ is defined: %d bytes\n", __SIZEOF_INT128__);
#else
  // Try a test for __int128 availability
  __int128 test = 1; // If this compiles, __int128 is supported.
  printf("__SIZEOF_INT128__ is not defined, but __int128 is supported.\n");
#endif
  return 0;

The output suggests that Int128 is defined.

__CUDACC__ defined
__SIZEOF_INT128__ is defined: 16 bytes

it seems the compiler thinks unsigned long long is not the same type with uint64_t, I used uint64_t instead then the error is gone.

The size of unsigned long long is architecture-dependent and, therefore, not guaranteed to match uint64_t. We are tracking the addition of INT128 support for Hopper GPUs and newer architectures in #547. Please refer to it for updates on this feature request.
