Re: [Boost-users] [Serialisation] Explicit instantiation of serializewhen used in library

Ignore post - have figured it out - couple of errors - because I am
instanatiating a function, not the whole class, I needed to remove the
class statement, and secondly, I had missed out the void as the return
type for the serialise function

This works.

template void
LCPanel::serialize<boost::archive::xml_iarchive>(boost::archive>::xml_ia
r> chive&, unsigned int)

And now application links to library no problem.
