Hi Philip,

Which structure must be implementated for the class myThread and from which class must be derived?

no need for derivation. Just implement operator() for your class like so:

class myThread { public some methods

void operator()() { // this will run in new thread }

private some properties } I get with this use compiler errors, this code

boost::thread_group l_group; for(std::size_t i=0; i < 5; ++i)

l_group.join_all();

shows: error: no match for call to '(boost::thread_group) (myThread)'

on the loop line I have tested

l_group( boost::thread(myThread) );

and creates the error:

error: no match for call to '(boost::thread_group) (boost::thread)

In my class "myThread" I have a overloaded public method: void operator() (void);

How can I fix the error?

To create and add a new thread to a thread_group you should use Member function |create_thread()| template<typename F> thread* create_thread(F threadfunc); Effects: Create a new |boost::thread| object as-if by |new thread(threadfunc)| and add it to the group. Postcondition: |this->size()| is increased by one, the new thread is running. Returns: A pointer to the new |boost::thread| object. l_group.create_thread( myThread() ); Best, Vicente
