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.
Daniel, What Robert failed to mention is that the whole **purpose** of BOOST_STATIC_ASSERT is to cause a compilation error using sizeof when some condition is violated. I sure wish people would stop using BOOST_STATIC_ASSERT in favor of one of the MPL_ASSERT macros, because the error messages are so much better and would lead to less confusion and easier support. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
