[Boost-users] Boost, MinGW and SjLj

Hi, I have compiled boost_1_53_0 using bjam on windows with MinGW (gcc-4.6.3). I am using CodeBlocks for IDE and have successfully linked against Qt5. Attempting to link against libboost_serialization produces undefined references to things like sjlj_unwind and archive_exception. What's going wrong? Do I need to flag the compiler to change exception strategy? Thanks in advance. Archie
