I'm trying to build Boost.Signals on a Debian-based (Nokia Maemo OS2008 Diablo) system which is using GCC 3.4.4 toolchain (CodeSourcery ARM 2005q3-2). Problem is when linking, I get duplicate symbol boost::exception_detail::make_clone<boost::exception_detail::error_info_injector<boost::bad_weak_ptr>
(boost::exception_detail::error_info_injector<boost::bad_weak_ptr>
in trackable.o named_slot_map.o Details see below. Any hints? Thanks alot, tgo [sbox-DIABLO_ARMEL: ~/build/boost_1_36_0] > bjam --toolset=gcc --build-dir=/home/oberstet/tmp/boost --with-signals warning: Graph library does not contain optional GraphML reader. note: to enable GraphML support, set EXPAT_INCLUDE and EXPAT_LIBPATH to the note: directories containing the Expat headers and libraries, respectively. warning: skipping optional Message Passing Interface (MPI) library. note: to enable MPI support, add "using mpi ;" to user-config.jam. note: to suppress this message, pass "--without-mpi" to bjam. note: otherwise, you can safely ignore this message.
