Hey all! Perhaps I should have addressed this directly to Robert Ramey. I'm trying to use his (great!) serialization library and having trouble getting basic serialization code to compile, using boost cvs (updated a few minutes ago). I tried building the examples bundled with the lib and get the same error as I do with my simple code, when compiling demo_exception.cpp. I'm pretty new at this, so I wouldn't rule out "user error" of some kind, but I get the same error under Fedora FC3 and gentoo, and another developer on #boost has confirmed that they also get the error under Solaris. Here are my compiler versions: gcc (GCC) 3.4.3 20050227 (Red Hat 3.4.3-22.fc3) gcc (GCC) 3.3.5-20050130 (Gentoo 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, pie-8.7.7.1) Here's the error: /home/m/development/boost_cvs/boost/boost/archive/detail/oserializer.hpp:543: error: incomplete type `boost::STATIC_ASSERTION_FAILURE<false>' does not have member `value' See below for the full error context. OK I now see from the mailing list that it's a const problem, that darn creeping const. :> Still, it looks like the demo code needs updating, for const* but perhaps more. From Bklyn on #boost... <reboost> FN: <Bklyn> ok, fix for demo_Exception.cpp: <reboost> FN: <Bklyn> change the "save" free function so it takes a School* const instead of School* <moodboom> cool! :> <reboost> FN: <Bklyn> the shared_ptr demo is broken tho <reboost> FN: <Bklyn> its using internals of shared_ptr that no longer exist I think <moodboom> ok TIA for any help, Michael Behrns-Miller --------------------------------------------- cd boost/libs/serialization/example bjam "-sTOOLS=gcc" ...found 1209 targets... ...using 26 temp targets... ...updating 13 targets... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_archive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_archive_impl.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_iarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_oarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_iserializer.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_oserializer.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_pointer_iserializer.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_pointer_oserializer.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_serializer_map.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_text_iprimitive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_text_oprimitive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>basic_xml_archive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>binary_iarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>binary_oarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>extended_type_info.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>extended_type_info_no_rtti.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>extended_type_info_typeid.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>polymorphic_iarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>polymorphic_oarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>stl_port.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>text_iarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>text_oarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>void_cast.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>xml_grammar.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>xml_iarchive.o... ...using <@boost!libs!serialization!build/libboost_serialization.a/gcc/debug>xml_oarchive.o... gcc-Archive-action ../../../bin/boost/libs/serialization/build/libboost_serialization.a/gcc/debug/libboost_serialization-gcc-d-1_33.a system-Ranlib ../../../bin/boost/libs/serialization/build/libboost_serialization.a/gcc/debug/libboost_serialization-gcc-d-1_33.a gcc-Link-action ../../../bin/boost/libs/serialization/example/demo/gcc/debug/demo Chmod1 ../../../bin/boost/libs/serialization/example/demo/gcc/debug/demo gcc-Link-action ../../../bin/boost/libs/serialization/example/demo_auto_ptr/gcc/debug/demo_auto_ptr Chmod1 ../../../bin/boost/libs/serialization/example/demo_auto_ptr/gcc/debug/demo_auto_ptr gcc-C++-action ../../../bin/boost/libs/serialization/example/demo_exception/gcc/debug/demo_exception.o /home/m/development/boost_cvs/boost/boost/archive/detail/oserializer.hpp: In function `void boost::archive::save(Archive&, T&) [with Archive = boost::archive::text_oarchive, T = School*]': /home/m/development/boost_cvs/boost/boost/archive/basic_text_oarchive.hpp:78: instantiated from `void boost::archive::basic_text_oarchive<Archive>::save_override(T&, int) [with T = School*, Archive = boost::archive::text_oarchive]' /home/m/development/boost_cvs/boost/boost/archive/detail/interface_oarchive.hpp:92: instantiated from `Archive& boost::archive::detail::interface_oarchive<Archive>::operator<<(T&) [with T = School*, Archive = boost::archive::text_oarchive]' demo_exception.cpp:219: instantiated from here /home/m/development/boost_cvs/boost/boost/archive/detail/oserializer.hpp:543: error: incomplete type `boost::STATIC_ASSERTION_FAILURE<false>' does not have member `value' -------------- (snip) -------------- ...failed updating 3 targets... ...skipped 2 targets... ...updated 8 targets...
