Passing a class to a thread function

Question

Hi i'm learning to use queue and i'm trying to make a simple read and write program. i have 2 thread 1 that sends the message got from std::cin and the other thread that waits for the queue to not be empty and prints the content when there's something in the queue. But when i execute my program the receiver receives nothing i think it's because they don't have the same object so i tried to give the reference to the object but it doesn't work i got this error message :

In file included from main.cpp:2:
