Just started experimenting with the serialization library. I started by writing a small example very much like that shown in the tutorial. I created a simple class to serialize containing two unsigned int vars and an std::string This is close to what I would need to do once I move beyond familiarizing myself with the use of the library. When I compile I get errors in the boost code: s-test.h:49: instantiated from here /usr/include/boost/archive/detail/oserializer.hpp:567: error: invalid application of 'sizeof' to incomplete type 'boost::STATIC_ASSERTION_FAILURE<false>' make: *** [stest] Error 1 When I look at boost static assert I find this: #define BOOST_STATIC_ASSERT( B ) \ typedef ::boost::static_assert_test<\ sizeof(::boost::STATIC_ASSERTION_FAILURE< (bool)( B ) >)>\ BOOST_JOIN(boost_static_assert_typedef_, __LINE__) #endif Which I believe is macro expansion sizeof that is being complained about. I'm using boost 1_35_0 (release tarball), gcc 4.1.2, Fedora 7. Looking for hints as to where to go from here.
