Bug fixes

  • std::void_t was introduced only in C++17; switched to using a custom implementation (Issue 180).
  • Fixed two independent bugs in native/src/CMakeConfig.cmd: The first prevented SEAL to be built in a directory with spaces in the path due to missing quotation marks. Another issue caused MSVC to fail when building SEAL for multiple architectures.
  • RNSBase::decompose_array had incorrect semantics that caused Evaluator::multiply_plain_normal and Evaluator::transform_to_ntt_inplace (for Plaintext) to behave incorrectly for some plaintexts.

Other

  • Added pkg-config support (PR 181).
  • seal::util::PtrIter<T *> now dereferences correctly to T & instead of T *.
    This results in simpler code, where inside SEAL_ITERATE lambda functions dereferences of seal::util::PtrIter<T *> do not need to be dereferenced a second time, as was particularly common when iterating over ModulusIter and NTTTablesIter types.
  • seal::util::IterTuple now dereferences to an std::tuple of dereferences of its component iterators, so it is no longer possible to directly pass a dereferenced seal::util::IterTuple to an inner lambda function in nested SEAL_ITERATE calls.
    Instead, the outer lambda function parameter should be wrapped inside another call to seal::util::iter before passed on to the inner SEAL_ITERATE to produce an appropriate seal::util::IterTuple.
