Hi All, I am in the process of trying to get boost task compiled and working with Boost 1.43.0. As far as I can tell it relies on boost fiber and boost context as well so I got them from the boost vault. I am using: * boost.context-0.2.0 * boost.fiber-0.5.1 * boost.task-0.4.2 I have copied these into my boost 1.43.0 build area and have run bjam as normal: Component configuration: - context : not building - date_time : not building - fiber : building - filesystem : not building - graph : not building - graph_parallel : not building - iostreams : not building - math : not building - mpi : not building - program_options : not building - python : not building - random : not building - regex : not building - serialization : not building - signals : not building - system : not building - task : not building - test : not building - thread : not building - wave : not building Below is the first couple errors I get but all of the following errors are of the same type: .\boost/fiber/strategy.hpp(123) : error C2492: 'boost::fibers::strategy::active_ fiber' : 'thread' data may not have dll interface .\boost/fiber/strategy.hpp(123) : error C2492: 'protected: static boost::fibers: :fiber * boost::fibers::strategy::active_fiber' : 'thread' data may not have dll Interface This seems to have to do with the __declspec(thread) but I am not very familiar with that so I can't really do much debugging. My build environment is: Windows XP64 VisualStudio 2008 Thanks in advance for any help. Glenn
