Hi all, I'm a new user of BOOST library. I'm creating a class that requires to do some multi threading stuff. The class I'm creating has a method... void Calculator::Calc(int value) { ... } In order to run multiple Calc() in different threads, I created another method FindResult() the implementation was... void Calculator::FindResult(int numbers) { thread_group group; boost::function boostFunction; boostFunction = &Calculator::Calc; for(int i=0; i<3; i++) { boost::thread * th = group.create_thread(&boostFunction); } } However, it seems it doesn't work at all... Is there any idea?? Cheers, -- Alexander Dong Back Kim Australia +61 433 469 100 / Korea +82 10 6357 8840
