Hello all,
I would like to use boost::serialize for one of my projects, using Codewarrior 8.3 (going to CW 9 may or may not be in the picture), on Mac OS X (10.3.x)
Anyway, I've been working on getting the unit tests for boost::serialize up and running inside the Codewarrior IDE. I created a new project file (C++, Mac OS Carbon, Console), included a serialize unit test, set the paths correctly, included the files I thought I would need for boost::test stuff, all that jazz.
The test that I'm trying out now, in the serialization test suite, is test_binary.cpp. Trying to compile it gave me some immediate compiler errors (which I fixed by #including some additional source files: "binary_archive.hpp", "stdio.h" (tmpnam is in stdio.h in CW, and not cstdio).
At the end I have just one error which I don't understand (both because the error message is hard to parse, and I'm fairly new to the boost libraries in general).
Here, for completeness, is the error message:
Error : illegal use of abstract class ('boost::archive::detail::basic_iserializer::load_object_data(boost: :archive::detail::basic_iarchive &, void *, const unsigned int) const') ~ (point of instantiation: 'test_main(int, char **)') ~ (instantiating: 'boost::archive::detail::interface_iarchive<boost::archive: :binary_iarchive>::operator>><boost::serialization::nvp<A>>(const boost::serialization::nvp<A> &)') ~ (instantiating: 'boost::archive::binary_iarchive_impl<boost::archive::binary_iarchive>: :load_override<boost::serialization::nvp<A>>(boost::serialization::nvp<A> &, int)') ~ (instantiating: 'boost::archive::basic_binary_iarchive<boost::archive::binary_iarchive>: :load_override<boost::serialization::nvp<A>>(boost::serialization::nvp<A> &, int)') ~ (instantiating: 'boost::archive::load<boost::archive::binary_iarchive, boost::serialization::nvp<A>>(boost::archive::binary_iarchive &, boost::serialization::nvp<A> &)') ~ (instantiating: 'boost::archive::detail::load_non_pointer_type<boost::archive: :binary_iarchive, boost::serialization::nvp<A>>::invoke(boost::archive::binary_iarchive &, boost::serialization::nvp<A> &)') ~ (instantiating: 'boost::archive::detail::load_non_pointer_type<boost::archive: :binary_iarchive, boost::serialization::nvp<A>>::load_only::invoke(boost::archive: :binary_iarchive &, boost::serialization::nvp<A> &)') ~ (instantiating: 'boost::serialization::serialize_adl<boost::archive::binary_iarchive, boost::serialization::nvp<A>>(boost::archive::binary_iarchive &, boost::serialization::nvp<A> &, const unsigned int)') ~ (instantiating: 'boost::serialization::serialize<boost::archive::binary_iarchive, boost::serialization::nvp<A>>(boost::archive::binary_iarchive &, boost::serialization::nvp<A> &, const unsigned int)') ~ (instantiating: 'boost::serialization::access::serialize<boost::archive::binary_iarchive, boost::serialization::nvp<A>>(boost::archive::binary_iarchive &, boost::serialization::nvp<A> &, const unsigned int)') ~ (instantiating: 'boost::serialization::nvp<A>::serialize<boost::archive: :binary_iarchive>(boost::archive::binary_iarchive &, const unsigned int) const') ~ (instantiating: 'boost::archive::detail::interface_iarchive<boost::archive: :binary_iarchive>::operator&<A>(A &)') ~ (instantiating: 'boost::archive::binary_iarchive_impl<boost::archive::binary_iarchive>: :load_override<A>(A &, int)') ~ (instantiating: 'boost::archive::basic_binary_iarchive<boost::archive::binary_iarchive>: :load_override<A>(A &, int)') ~ (instantiating: 'boost::archive::load<boost::archive::binary_iarchive, A>(boost::archive::binary_iarchive &, A &)') ~ (instantiating: 'boost::archive::detail::load_non_pointer_type<boost::archive: :binary_iarchive, A>::invoke(boost::archive::binary_iarchive &, A &)') ~ (instantiating: 'boost::archive::detail::load_non_pointer_type<boost::archive: :binary_iarchive, A>::load::invoke(boost::archive::binary_iarchive &, A &)') ~ (instantiating: 'boost::archive::detail::iserializer<boost::archive::binary_iarchive, A>::instantiate()') iserializer.hpp line 142 static iserializer instance;

I don't, really, understand why there's an error here, as iserializer is ~ a non-abstract type (as far as I can see), but it looks like there's plenty of template stuff going on, and there may be a clue in there.
Does anyone have any pointers, or ideas on how I can fix this error?
I think you're looking at the wrong end of the stick: Error : illegal use of abstract class ('boost::archive::detail::basic_iserializer::load_object_data(boost: :archive::detail::basic_iarchive &, void *, const unsigned int) const') I think this says that load_object_data() is an illegal use of an abstract class. I haven't used the serialization library so I can't help much past trying to point in the right direction. ...Duane
