I grabbed coroutine lib from http://olk.bplaced.net/boost-coroutine.zip and I am getting linker errors with VC2008 SP1 when trying to compile simplest example from coroutine's documentation: Error 1 error LNK2019: unresolved external symbol _jump_fcontext referenced in function "public: int __thiscall boost::coro::detail::context_base::native_start(void)" (?native_start@?$context_base@$$A6AXXZVstack_allocator@ctx@boost@@X$0A@@detail@coro@boost@@QAEHXZ) main_2.obj context Error 2 error LNK2019: unresolved external symbol _make_fcontext referenced in function "public: __thiscall boost::coro::detail::context_base::context_base(class boost::ctx::stack_allocator const &,unsigned int,enum boost::coro::flag_unwind_t,bool)" (??0?$context_base@$$A6AXXZVstack_allocator@ctx@boost@@X$0A@@detail@coro@boost@@QAE@ABVstack_allocator@ctx@3@IW4flag_unwind_t@23@_N@Z) main_2.obj context btw, old documentation link (http://ok73.ok.funpic.de/boost/libs/context/doc/html/) for boost.context does not work anymore and I remember it had continuation example which is not included in library examples. Any way to get it back? -- Szymon Gatner The Lordz Games Studio www.thelordzgamesstudio.com
