When I compiled homomorphic multiplication using SEAL4.0, the following error was reported.
This is my c++ code.
void multiply_by_random_mask(Ciphertext &ciphertext,
shared_ptr<UniformRandomGenerator> random,
BatchEncoder &encoder,
Evaluator &evaluator,
RelinKeys &relin_keys,
uint64_t plain_modulus) {
size_t slot_count = encoder.slot_count();
vector<uint64_t> pod_vector;
for (size_t j = 0; j < slot_count; j++) {
pod_vector.push_back( random_nonzero_integer(random, plain_modulus));
}
Plaintext mask;
encoder.encode(pod_vector, mask);
evaluator.multiply_plain_inplace(ciphertext, mask);
evaluator.relinearize_inplace(ciphertext, relin_keys);
}
Always output the following during compilation:
/usr/local/include/SEAL-4.0/gsl/span: In instantiation of ‘constexpr gsl::span<ElementType, Extent>::span(Container&) [with long unsigned int MyExtent = 18446744073709551615; Container = seal::Plaintext; typename std::enable_if<(((((MyExtent == gsl::dynamic_extent) && (! gsl::details::is_span<Container>::value)) && (! gsl::details::is_std_array<Container>::value)) && std::is_pointer<decltype (declval<Container&>().data())>::value) && std::is_convertible<typename std::remove_pointer<decltype (declval<Container&>().data())>::type (*)[], ElementType (*)[]>::value), int>::type <anonymous> = 0; ElementType = const long unsigned int; long unsigned int Extent = 18446744073709551615]’:

How can I modify my code to eliminate existing errors?
