I'm trying to use a packaged_task, and get an error on creation.
template<typename R,typename F> struct task_object: task_base<R> { F f; task_object(F const& f_): // << refers to look here f(f_) {} #ifndef BOOST_NO_RVALUE_REFERENCES task_object(F&& f_): // <<<< Error here f(f_) {}
E:\boost_1_49\boost/thread/future.hpp(1251): error C2535: 'boost::detail::task_object<R,F>::task_object(F)' : member function already defined or declared with [ R=size_t,

Can you provide a trivial example that reproduces the issue? #include <boost/thread.hpp> int main() { ??? }
