I am trying to use the boost serialization library but can't compile even the simplest demo. The result of attempted compilation is below. Any help would be appreciated. In particular, does anyone know of a *simple* example (with Makefiles, not jam-files) which works with gcc? Something similar to the one quoted 2.5 years ago here: http://aspn.activestate.com/ASPN/Mail/Message/boost/1437547 (this one is for the previous version of boost and does not work out of the box now). thanks, alex system: Debian Linux boost 1.32 gcc 3.3.5 ========================= $ g++-3.3 -Wall -o demo demo.cpp In file included from /usr/local/include/boost/config.hpp:35, from /usr/include/boost/serialization/utility.hpp:21, from demo.cpp:16: /usr/local/include/boost/config/compiler/gcc.hpp:57:7: warning: #warning "Unknown compiler version - please run the configure tests and report the results" In file included from /usr/include/boost/serialization/type_info_implementation.hpp:24, from /usr/include/boost/serialization/traits.hpp:33, from /usr/include/boost/serialization/nvp.hpp:22, from /usr/include/boost/serialization/utility.hpp:23, from demo.cpp:16: /usr/include/boost/serialization/extended_type_info_typeid.hpp:108: error: parse error before `::' token In file included from /usr/include/boost/serialization/type_info_implementation.hpp:30, from /usr/include/boost/serialization/traits.hpp:33, from /usr/include/boost/serialization/nvp.hpp:22, from /usr/include/boost/serialization/utility.hpp:23, from demo.cpp:16: /usr/include/boost/mpl/eval_if.hpp:67: error: wrong number of template arguments (3, should be 2) /usr/local/include/boost/mpl/lambda_fwd.hpp:28: error: provided for ` template<class T, long int Arity> struct boost::mpl::lambda' /usr/include/boost/mpl/eval_if.hpp:67: confused by earlier errors, bailing out =========================
