Re: [Boost-users] Android: segfault while writing to archive during Serialization

./boost/archive/impl/xml_iarchive_impl.ipp:71:error: undefined reference to 'mbtowc' (four instances of that in that file) ./boost/archive/iterators/mb_from_wchar.hpp:91 error: undefined reference to 'wctomb' (two instances of that in that file)

Alas, it seems that these functions are still missing in the NDK, that's a bad surprise. I believe you can take their implementation from Crystax NDK or from "The Standard C Library" book, as proposed in one of the answers on SO.
