Embind doesn't support pointers to primitive types. "Pi" means to "pointer to integer."

If you will always know the size of the array in advance, you could try passing the array as a const reference. e.g.

std::vector intArrayToVector(const int (&input)[100])

Or you can cheat and use an integer parameter for the pointer and use reinterpret_cast to treat it as a pointer. e.g.

std::vector intArrayToVector(uintptr_t input, size_t len) {
    const int* ptr = reinterpret_cast(input);
    ....
}

Or you can use the cwrap API which does support pointers to primitive types.
